What is rice shell ash

rice shell ash is a by -product made of rice shell, rice bran and broken rice. It can be made into various useful products after processing.

The main component of rice shell ash

The rice shell ash is mainly composed of silicon dioxide and unfamiliar carbon. The content of silicon dioxide is generally more than 80%, but the shape of the silicon dioxide is related to the incineration temperature of the rice shell.

How much is the rice shell ash a bag

The sale of rice shell ash on the market is generally calculated by Bags. At present, the latest price range of rice shell ash is 6 yuan/bag-25 yuan/bag. The specific price is based on the actual market situation.

What is the use of rice shell ash for plants

1. Keep warm

The rice shell charcoal often acts on Succulent plants. When cutting, a small amount of rice shell charcoal is mixed when cutting, which can promote the growth of the root system and the cutting survival rate is relatively high.In addition, in winter, a small amount of rice shell charcoal can be added to keep warm and avoid frosting plants.

2. Promote flowering results

The main ingredients of rice shells are phosphorus and potassium Fertilizers. Everyone applies phosphorus and potassium Fertilizers when farming.Therefore, adding an appropriate amount of rice shell charcoal before the flowering period of flower and plant can play a role in promoting flowering results.In addition, the permeability of potting soil can be increased to regulate soil pH.

3, absorbing and humidity reduction

A very large characteristic of rice shell ash is the moisture absorption, which can absorb too much moisture in the air. While absorbing and moisturizing, it will reduce the chance of plant disease.

4. Referred insulation

The rice shell ash is equivalent to an insulation layer on the soil layer.In the case of hot weather, for example, when the summer of April is coming in April, the air temperature will gradually rise. At this time, adding a layer of rice shell coverage will instead the heat insulation.

How to use rice shell ash correctly

The rice shell ash is a common farm fat, but it does not mean that the more it is applied, the better. Generally speaking, 5%-10%of the amount of soil is applied.You can, mixing flowers in water.

Here we have to talk to the flower friends that the phosphorus and Potassium fertilizer in the rice shell ash is soluble, so if it is sprinkled on the surface of the Flower pot, pay attention to watering and drizzling in time, so that the Fertilizer effect can be absorbed by plants into the soil.

What does it mean to control the Fertilizer?

Controlling Fertilizer is a high -form form of slow -release Fertilizer. It mainly controls the release of nutrients through envelope technology to achieve the purpose of safe, long -term and efficient. It is the main direction of modern Fertilizer development. It is suitable for mechanized production. The broadcast needs to wait.

What are the characteristics of controlling Fertilizer

The first is to increase the utilization rate of chemical Fertilizers and reduce the amount of Fertilizer.

Because controlling and release of Fertilizer has a slow -release effect, it can reduce the gaseous and leaching loss of chemical Fertilizers, thereby improving the efficiency of the utilization of chemical Fertilizers.The test data shows that the controlling Fertilizer can increase the utilization rate of Fertilizers from about 35%, and the loss rate of nitrogen fertilizer is significantly reduced, which can save 30%-50%of nitrogen fertilizer.

The second is to reduce the number of Fertilizers and save labor.

Due to the lack of labor in rural areas or due to lack of water and inadequate water supply, crop fertilization is becoming increasingly simplified, and one -time fertilization of crops is quite common.At present, the one -time Fertilizer sold on the market is basically fast -acting high -nitrogen -type Compound fertilizer, and there is a risk of long -term seedling or later Fertilizer.The release of the release of Fertilizer can be scheduled to design the release mode of the Fertilizer in the growth season of the crop, so that the law of the nutrient release of the Fertilizer is consistent with the absorption of crop nutrition, and one -time fertilization meets the needs of the entire growth season of crops.

Controlling Fertilizer can also be used for cultivation of farming and soil -free cultivation. seeds and Fertilizers can be sowed, and irrigation is sufficient, which is very convenient.Many soil -free cultivation of irrigation nutrient solution.Sometimes the nutrient solution is not well matched, and the Miao Changshi is not good. It solves this problem with controlling Fertilizer.

The third is to reduce crop disease and improve the quality of agricultural products.

Crop disease and product quality are related to the amount of nitrogen fertilizer. Applying controlling and release Fertilizer can prevent crops from absorbing excessive absorption of nitrogen, thereby suppressing diseases and improving quality.

How to use release Fertilizer

When using, Fertilizer isolates and covers soil after application. For example, when planting corn and cotton crops, the distance between the seeds and Fertilizers is about 7-10 cm, the depth of fertilization and sowing is about 10 cm.

Note:

1. When the use of controlling Fertilizer is used, the amount can generally be applied according to 80%of the Fertilizer in previous years. At the same time, it is necessary to increase or decrease appropriately according to different crops, target yield, and soil conditions.

2. Not suitable for the use of drought land and sandy land.In the absence of moisture, nutrients cannot be effectively released, which may cause crops to affect the growth due to the inability to absorb effective nutrients and cause crop production to reduce production.

The difference between control release Fertilizer and slow release Fertilizer

Control and release Fertilizer: It mainly controls the release of nutrients by performing envelope on the Fertilizer. The Fertilizer has a longer Fertilizer and more nutrients, but it is only suitable for use in the peak of the crop. , Roots and mountain spray irrigation.

Smooth -release Fertilizer: The Fertilizer effect is relatively slow, and its composition is relatively single. The main elements contained in are nitrogen elements, and the water solution itself is relatively low.

The difference between controlling and Compound fertilizer

Control and release Fertilizer: It mainly controls the release of nutrients through envelope technology. The Fertilizer effect is longer, and the nutrients containing are relatively comprehensive, but it is only suitable for crops to use it at the peak of the need for Fertilizer. Roots, mountain spray irrigation, etc.

Compound fertilizer: It mainly contains nitrogen, phosphorus, potassium and other elements. It is generally appropriate to fertilize (gap, acupuncture, etc.) when fertilizing, and it is usually used as base Fertilizer.

The wonderful use of sawdust on flowers

1. The bandaging matrix of high branches

In the Meiyu season, the growing plant branches that were growing last year were selected to peel the ring 10-15 cm from the top of the top, and then wrapped in plastic Bags.Tighten the end, and then place the pot flower in the half -yin and half -yang to carry out daily maintenance management.You can take root in 2 to 3 months. After rooting, you can cut the mother plant into a new flower seedling.

2. The rooting matrix of plant cutting

Take a plastic film with a slightly longer height and a certain length, and spread the wet sawdust (pinch without dripping water), and then press the cuttings at a distance of 2 to 3 cm.~ 2 cm.Finally, it is tightly rolled, and every 10 to 20 cuttings are tied, each tied with large plastic film Bags, and tightened the bag to moisturize.Because the humidity is easy to control, the hair root is fast.

3, fat

Mix and mix with human dung urine, dress with plastic Bags, tighten the bag, place it at the temperature of 30 C to 35 C, and ferment and rot after 1 to 2 months.After fermentation and rotten sawdust, the nutrition is comprehensive, which will not make plants be nitrogen -deficient in phosphorus and potassium, and the texture is loose, and the dry and wet is moderate. It is a simple soil -free cultivation material, especially suitable for potted bamboo and orchids.After the fermentation and disinfection, after adjusting the acidity and alkali, the substrate of transitional cultivation after the test Tube seedlings is out of the bottle. The effect is as good as the perlite powder.

4. Made into Nutritional soil

If the sawdust is placed directly in the Flower pot, fermentation in the Flower pot will cause the flower root system to burn. Therefore, the sawdust needs to be placed in a plastic bag and add an appropriate amount of water.Its natural fermentation, about 3 months of sawdust rot into dark brown, can be used to cultivate flowers.

How to use the fermented sawdust

When the soil is equipped, you can add one -tenth of the fermentation sawdust, or it can be covered on the surface of the soil for flower Fertilizer in the later stage.

precautions for sawdust can raise flowers

1. In late autumn and winter, the temperature decreases. At this stage, most of the potted plants are mainly based on the cold prevention and warmth of the winter. At this time, fertilization can not be applied at this time.

2. There are no rotten things, including sawdust, not suitable for Fertilizer for flower plants. If it is placed in a Flower pot, it will produce the root system of the plants during the fermentation process, which will cause rotten roots of yellow leaves and other states.If you appear, it will be lost.

3. When sawdust fermentation, generally 20 days of fermentation in summer, fermentation of two or three months in spring and autumn, the fermented sawdust color will change from white to brown.Used.If there is not much sawdust, put it directly into the plastic bag, it will ferment.

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 ~
