1. What are the types of compound Fertilizers

Compound fertilizer can be divided into three types: compound Compound fertilizer, mixed Compound fertilizer, and mixed hybrid Compound fertilizer according to the manufacturing method.

1. Huahe composite Fertilizer

The compound Fertilizers made through chemical methods generally belong to dual -type complex Fertilizers and have no side components.Such as ammonium phosphate, nitrate phosphate Fertilizer, potassium nitrate, and potassium phosphate are typical compound Fertilizers.

2. Mix mixing Hefei

The compound Fertilizers made of several Fertilizers by mechanical mixing are simply mixed in the process of processing without chemical reactions, such as the ternary complex Fertilizer mixed with ammonium phosphate and potassium sulfate and Urea solid bulk.

3. Mixed Compound fertilizer

It is a Compound fertilizer that uses two or more monocular Fertilizers in the Chemical Fertilizer manufacturer through a certain processing process and contains multiple elements. Some chemical reactions occur during processing.Refers to this kind of Compound fertilizer.Most of them belong to the three yuan Fertilizers and often contain sub -scores.Such as ternary reptry Fertilizer such as Urea phosphate, potassium of ammonium phosphorposcopy, and potassium of ammonium nitrate.

2. What is the effect of Compound fertilizer

1. Promote crop growth

Compound fertilizer contains nitrogen fertilizer, phosphorus Fertilizer and other elements required for plant growth, which can meet the growth of plants. Therefore, Compound fertilizer can be applied to plants during the growth of plants or the maturity of fruits.

2. Balance fertilization

There are many types of nutritional elements of Compound fertilizer. At a time, Compound fertilizer can be applied at least at the same time. At least at the same time, more than two main nutritional elements of crops can be supplied, which can give full play to the mutual promotion of nutritional elements to ensure the balanced supply of crop nutrition.Essence

3. Improve crop quality

Compound fertilizer also has the effect of improving the quality of crops. Therefore, if the quality of the crop is poor, it is likely that it is caused by the lack of Fertilizer, which can apply Compound fertilizer for plants.

4. Improve Fertilizer utilization

The proportion of compound Fertilizers is matched according to the nutrient characteristics of the soil and the nutritional characteristics of crops, which can effectively improve the utilization rate of Fertilizer.

5. increase output

Compound fertilizer can also effectively increase the production of crops. Therefore, if the production of crops is relatively low, Compound fertilizer can be appropriately applied to the crop.

1. What Fertilizer is biological Organic fertilizer

Bio -Organic fertilizer is very environmentally friendly and does not produce secondary pollution, and the utilization rate is high.So what is the material of biological Organic fertilizer?

Bio -Organic fertilizer refers to a type of microbial Fertilizer and organic material and organic materials that are mainly based on the residue of animals and plants (such as livestock and poultry feces, crop straws, etc.) as the source and harmlessly treated and rotten organic materials.Fertilizer with Fertilizer effect.

It can also be said that biological Organic fertilizer phase is a new material for traditional Organic fertilizer. It is a big development space in the future and can replace the green Fertilizer of chemical Fertilizers.

2. What are the standards for Organic fertilizer execution?

The national standard of Organic fertilizer is NY 884-2012.

The organic matter content should be 40%.Effective living bacteria per gram are greater than equal to 200 or 200 million.The water content 30%.The pH value requires between 5, 5 ~ 8, and 5, which means that strong acid and alkaline cannot be said.The number of fecal colorectal population is less than 100 per gram.The mortality rate of corhels is more than 95 %.The validity period is that the shelf life should be more than six months or six months.

Then there is the detected toxic and harmful heavy metal. The total arsenic content per kilogram is 15 mg, total lead fifty mg, total cadmium three mg, total chromium 150 mg, total mercury two mg.

There is no regulation on the content of nitrogen, phosphorus, and potassium.Generally, domestic Organic fertilizer will write 5%in the packaging bag.

Remarks: The specific content can be viewed on the official website of the Ministry of agriculture. This is mainly to introduce some important execution standards ~

1. What are the coverage of Shading nets?

In the southern area, the coverage of the shade net is mainly covered with floating surfaces, large, medium, and small flat sheds, large, medium, and small arch sheds covered, and there are also a small amount of greenhouse coverage.

1. Floating surface coverage

It refers to the coverage of the coverage directly on the ground or plant with a Shading net.The annual use of this method is mainly used for the coverage of vegetables from sowing to the seedling period, and the Shading net is unveiled after the seedlings.The effects of Shading, cooling, moisturizing, and riot rain in summer, the effects of preventing rain, heat preservation, and moisturizing in winter to create favorable conditions for seeds germination and seedlings.During the day, the method of unveiled at night to shorten the seedling period and improve the seedling rate. In addition, it can be used to cover the floating surface 7-10 days before the harvest of the late summer and autumn.

2. Single -type small flat shed covered

For the main coverage of leafy vegetables, bamboo poles, bamboo pieces, wooden sticks, cement columns and other materials can be used on the noodles of about 1 meter to cover the shade net.Generally, floating surface coverage after sowing or transplantation, the long-visited types of crops, weather and other conditions of the coverage time are depends on. The high temperature during summer and autumn should be covered by 15 days.Gaerry and cauliflower are covered with 20-25 days. Symphony, small mustard, lettuce, kale, celery, etc. can be covered with full fertility period. When the weather turns cold in autumn, kale, mustard, Chinese cabbage, broccoli, cauliflower, lettuce, etc.Cover 15-20 days.

3. Zhongping shed coverage

Use 1.5-1.8 meters long, 0.33 cm Planted pipes to set up a simple flat shed on the noodles, cover the sunshade net, and the Shading net should be flat and straight, about 1.5 meters high.50 cm, preventing the typhoon from being blown down. This method is simple, the cost is low, the field operation is also convenient, and the ability to resist typhoons is better.Suitable for leafy dishes, early or full -blooming.

4. High flat shed coverage

The height is 1.8-2.0 meters, and the cement column with a length of 2.2 meters and a thick 12 cm X10 cm is used as a water pipe and iron wire fixed bracket.There are more materials, installation, and low ability to resist typhoons.Suitable for leafy vegetables to cultivate or eggplant fruits, early coverage of melon Beans, etc.

5. Small and medium arched sheds cover

It refers to the use of the skeleton of small and medium arch sheds as support, covering the coverage of the shade net.It is mainly used for seedling, transplantation, early cultivation of autumn vegetables or anti -season cultivation.The center of the small shed is about 0.5-1.0 meters high, about 1.0-1.5 meters wide, 7-8 meters long or base blocks.The center of the middle shed is about 1.0-1.5 meters, 2-3 meters wide, 10-15 meters long or base blocks.

6. Greenhouse coverage

It refers to the use of cement, steel, etc. to cover the shade net for skeleton materials or cover the Shading net on a plastic film greenhouse.It is mainly used for seedling, summer and autumn vegetables delayed or early -maturing cultivation, and can also be used for some vegetables such as leafy dishes or some fruits of winter and anti -season cultivation.The center is about 2.5-3.0 meters, 6-12 meters wide, 40-55 meters long, and covers an area of 333.3-666.7 Square meters.

7. Greenhouse coverage

It refers to the coverage of the Shading net on the greenhouse.It can be divided into two ways: flat sheds on the top of the greenhouse and the flat shade net sky curtain in the greenhouse.Outdoor coverage is better than indoor coverage. It is good for ventilation and heat dissipation and cooling.It is mainly used for anti -season cultivation, postponed cultivation in summer, or early -maturing cultivation of autumn vegetables.

2. precautions for covering the shade net in summer

Covering the Shading net is the most commonly used cooling method in the high temperature season, but the wrong coverage method will affect the cooling effect and even play a negative role.

1. It is best not to close the shed

Black Shading nets absorb more heat, which will directly pass the heat to the shed to shorten the life of the shed film. At the same time, the heat of the coverage of the shed is slowly disappeared, and the ideal effect of cooling down can not be achieved.

How to use it correctly: It is recommended to keep a distance of 0.5-1 meters from the shade net and the shed surface to ensure that the air between the shade net and the shed surface can flow, which can accelerate the loss of heat in the shed, but also achieve a good Shading effect, reduce the shed shed sheds, reduce the shed sheds.Heat is hot.

Practice has proved that compared with the setting of the shade net and the shed film, the temperature in the former is 5 C or more than the latter.

How to make the shade net and the shed film open?

When a single greenhouse is covered with a Shading net, vegetable farmers can put two earth Bags with two film pressure membranes on the steel frame structure or large bamboo pole at a certain distance.

For bases or parks and places where greenhouses are relatively concentrated, automated Shading equipment can be used.During the specific settings, the steel pipe stent is preset at the back wall, the gables on both sides and the front face, about 1 meter from the shed, and the shed surface is equipped with a steel wire, covering the shade net on the steel wire, and the support network is set at 0.5 meters.Rope to fix the Shading net.

Finally, install the nose of the machine on the steel pipe at the front face of the greenhouse. In this way, just hold the remote control and press the button to easily complete the stretching of the shade net.At the same time, the Shading area can be flexibly adjusted in combination with weather conditions.

2. The Shading time should not be too long

The coverage of the shade net is too long, which will affect the photosynthesis of vegetables and is not conducive to the normal growth of vegetables.Vegetable Shading should be combined with weather conditions, vegetable types and vegetable growth stages. The requirements for light intensity and temperature are flexibly grasped.

Materials used for Shading, such as Shading nets, generally use sunny covers and unveil on cloudy days; lid at noon, in the morning and evening;If there are many rainy weather and the temperature is not too high. After the vegetables are planted, the shade material can only be covered in the slow seedling stage.In addition, when a long -term sun or root disease occurs, vegetable farmers can also use Shading nets to avoid the occurrence of plant withering.

How to make Fertilizers for expired Milk powder

Expired Milk powder has the following steps: fermentation process, fermentation complete, and dilution of water.

1. Select fermentation container:

The fermentation container can choose a clean plastic container. It is not recommended to use a glass bottle. This is because the Milk powder will generate gas during the fermentation process. If the exhaust is not Smooth, the glass bottle will burst.When fermenting with plastic containers, the bottle cap should not be twisted too tightly, leaving a gap, which is convenient for the gas generated by the fermentation.You can put some orange peels in the bottle to eliminate some odors.

2. Fermentation process:

Pour the expired Milk powder in the plastic container and determine the amount of Milk powder according to the size of the container.Add some rice water to the container to ferment Milk powder faster.Then use chopsticks to stir Milk powder and rice water well, and seal it and ferment under the sun.summer is usually fermented outdoors and the temperature is low in winter, and it should be fermented in a warm place indoors, but the time will be slightly slower.

3. Fermentation:

By observing the changes in the liquid, it is determined whether the fermentation is successful. When there is a significant layered in the plastic bottle, the color of the liquid is bright in color, and the lower layer has white solids like tofu, indicating that the fermentation may be successful.At this time, open the bottle cap. If you smell a sour smell, it proves that the fermentation is basically completed and can be used.

4. Dilute water with water:

The fermented solution is full, with high concentration, and it is easy to burn the root system directly. Therefore, it can be mixed according to the ratio of 1:20 before use, and it can be sprayed directly on the surface of the leaves to ensure that the branches and leaves have a stronger growth.

Can I make Fertilizers in the expiration Milk powder?

Can.

1. Expired Milk powder can be used as Fertilizer, but dairy flower Fertilizer is only suitable for Fertilizer plant, such as Milan, jasmine, rose such as rose.Orchids need to be used with caution. A large amount of protein contained in Milk powder can synthesize "nitrogen" with organic ingredients such as chlorophyll, so it can be used as flower Fertilizer.

2. If the expired milk already has a clear acid rot, you can use it to pour the flowers at this time, dig out a shallow gap on the edge of the flower soil, pour into the diluted milk and then cover it with soil.The fermented milk has a certain nutritional value to plant growth, which can supplement the nutrition required by plants.The protein in the expired milk after fermentation is decomposed into inorganic salts by bacteria for plant absorption.

What are the nutrients for expired Milk powder to do Fertilizers?

1. The main component of Milk powder:

The main component of Milk powder is protein. In the past, the content of nitrogen element in Milk powder was calculated, so as to estimate whether the protein content in the Milk powder meets the standard.The average mass score of nitrogen in protein is about 16%.It can be seen that the amount of nitrogen -containing elements in Milk powder is still very high, and crops and vegetables need a certain amount of nitrogen fertilizer during growth. Therefore, Milk powder can be used as Fertilizer for vegetable fields.However, it should be noted that Milk powder must be fermented for Fertilizer.

2. The role of nitrogen fertilizer in vegetables:

When spring farming is spring farming, whether it is Wheat, rice, apple trees, pear trees and various vegetables, they need to fertilize, including nitrogen fertilizer.The effect of nitrogen fertilizer on plants has the following two points:

Nitrogen is the main component of protein in crops. nitrogen fertilizer can improve the nutritional value of crops and increase the protein content in fruits and seeds. It can be said that without nitrogen elements, proteins cannot be formed in plants.Do not open the participation of protein.

The use of nitrogen fertilizer for vegetables can make the plant grow strongly, prevent yellowing and dryness of the leaves, and nitrogen fertilizer can promote the growth of the plant root system and increase branches.

Note: If the use of nitrogen Fertilizers is severe, it can lead to precocious precocious crops and vegetables and decrease in yield.If the nitrogen fertilizer is used too much, the plant growth can be too strong, the leaves are thick green, it is easy to fall, and the crop yield will be reduced.Therefore, the use of nitrogen fertilizer requires strict control.
