What are the effects of trace element Fertilizers

When a trace element is lacking, the growth and development of crops are significantly affected, the output decreases, and the quality decreases.On the other hand, excessive trace elements can poison crops, which affects production and quality lightly, and even endangers health.

What are the trace element Fertilizers

Those trace nutritional elements that are indispensable for normal growth and development of plants are agricultural as chemical products for Fertilizer. Like boron Fertilizer, zinc Fertilizer, manganese Fertilizer, molybdenum Fertilizer, copper Fertilizer, iron Fertilizer, cobalt Fertilizer, they are micro Fertilizers.These trace elements account for roughly: 0.05%manganese, 0.02%iron, zinc 0.01%, boron 0.005%, copper 0.001%, molybdenum 0.0001%.

1. Divided by nutrients:

(1) Single quality slightly fat.This type of Fertilizer generally contains only one trace element required for crops, such as zinc sulfate and iron sulfate.Most of these Fertilizers are easily soluble in water.Therefore, it is convenient to apply, can be used as base Fertilizer, Fertilizer, and topdressing.

(2) Compound micro -Fertilizer.Most of this type of Fertilizer is made of one or more trace elements when making Fertilizers. It includes a large amount of elements and trace elements and the composite between trace elements and trace elements.For example, ammonium phosphate zinc, ammonium phosphate manganese, etc.This type of Fertilizer, one time is applied to several kinds of nutrients at the same time, which is more labor -saved, but it is difficult to achieve local conditions.

(3) Mixed micro -Fertilizer.This type of Fertilizer is made of various single -quality Fertilizers when manufacturing or applied.

2. According to the type of micro -Fertilizer compounds:

(1) Easy -soluble inorganic salt.Most of these Fertilizers are sulfate.

(2) Unsaccharide inorganic salt.Most of them are phosphate and carbonate, and some are oxides and sulfur.For example, ammonium phosphate zinc, zinc chloride, etc.Suitable for base Fertilizer.

(3) glass Fertilizer.Most of the silicate powder containing trace elements, sintering or dissolving through high temperature

For glass -like substances, such as the stabs of the smelter, can generally only make bottom Fertilizer.

(4) Cheese Fertilizer.It is a compound of natural or artificial synthesis, chelated with trace elements, such as chelating zinc.

(5) Industrial waste with trace elements.

How to use trace element Fertilizers

1. Soil fertilization

In addition to chemical Fertilizers (such as borax, zinc sulfate, manganese sulfate, etc.), commonly used, as well as integrating Fertilizer, glass Fertilizer, slag, or lower foot material, they are usually used as base Fertilizers and planting Fertilizers.The application method is to be applied to the soil before sowing, or mixed with nitrogen, phosphorus, potassium and other chemical Fertilizers.For rice, zinc sulfate is applied for 1 kg per acre, and borax generally uses 0.5 kg to 1 kg per mu. It must be mixed with Organic fertilizer such as Fertilizer Fertilizer to prevent concentrated application of local hazards.

2. Follow the roots

The soluble micro -Fertilizer is distributed into a certain concentration of water solution, and the stems and leaves of the crop are sprayed.The advantage of this method is to avoid the harm caused by uneven Fertilizer in the soil. At the same time, it can also be sprayed multiple times according to specific needs in the different stages of the crops to improve Fertilizer effects.Conditional areas can use mechanical operations or aircraft spraying when applying large areas, and generally spray concentrations from 0.01%to 0.05%.

3. seed treatment

Wain the seeds or seedlings with trace elements before sowing. This is the most economical and effective method, which can greatly save Fertilizer.The concentration of soaking species of boric acid or borax is 0.01%to 0.03%.Only a solution of 5 liters per 500 kg of seeds.Soybean is mixed with ammonium molybdenonate and only 10 grams to 20 grams per acre.

1. Can branches and scissors bring the train?

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.

Note that at this time, it must be placed indoors.After about one or two days of sowing, keep the sowing soil moist at this time, so as not to cover soil out of seedlings.

6.Bleak(Coriander): Put the seeds of coriander before sowing, soak in water for half a day or a day like other seeds, and put the seeds at 20 C to 32 C after soaking.It can be sowed.

Vegetable seed electric blanket urging germination method

seed germination is the primary part of vegetable production, and an important technical measure for seedling and cultivation.It can not only make the seeds sprout neatly, shorten the age of seedlings, but also improve the quality of the seedlings and ensure the strong growth of the seedlings.Over the years, the author has carried out electric blankets for vegetable seeds and has received ideal fruits.The method of germination of electric blankets is now introduced as follows for reference for the application of vegetable farmers.

1. seed disinfection

In order to improve the vitality of the seeds, promote germination, and prevent the harm of pests and insects due to seed Belt bacteria. seed disinfection treatment should be performed before germination. The main methods are two types: hot water hot species and potion. Hot water hot: Wash the seeds with water before scalding, and use 55-600c hot water for 10-15 minutes.Note that the seeds should be stirred and stirred to heat the seeds evenly. Pharmaceutical soaking: Soak it with water for 1 hour before soaking, soak it with a medicinal solution. Use 0.1%-0.35%potassium permanganate solution for 20 minutes or use 1%copper sulfate, 2%sodium hydroxide solution 5---In 15 minutes, 20-30 minutes or 0.125 methamphetamine is soaked in 50%or 0.125 or 0.125 or 0.1%omportrait with 0.1%flat solution for 60 minutes.The above two disinfection methods should be taken out of the seeds to clean, soak, and germinate.

2, water soaking

The planting time should be soaked for 2 hours according to the types of vegetables, cucumbers, zucchini, vegetable Beans, etc., 4-5 hours of Pepper and eggplant, and the ascent of bitter gourd and watermelon for 24-36 hours.It can be scrubbed slightly when soaking to remove impurities and accessories.

3. Electric blanket germination

Put the electric blanket first, and then lay the plastic film (more than 2 times the area of the film is the electric blanket area) on the electric blanket, then scrub the towel in the water and wrap it on the surface of the film;Dry it, spread it evenly on the wet towel, fold the towel or use other wet towels to be gently covered in the south of the seed watch; fold it on the towel with the other half of the film, and then cover the turtle quilt, blanket or grass and other covers on the film.After the cover is completed, the power is powered on; the seeds are wrapped in the seeds every morning and evening to wash the seeds. After draining, the electric blanket is germinated until the seeds germinate.

4. Scope of application

Applicable to the germination of seeds such as vegetable Beans, cowpea, watermelon, bitter gourd, Cucumber, eggplant, Pepper, glutinous jade and other seeds;

It is suitable for germination and seedlings of a large number of seeds, small medium farms, watermelon bases, etc.

5. precautions

The hot water scald must be constantly stirred to avoid burns and hot seeds;

Power off the power when operating, and then power after the completion; seed hair buds and dew white up to 50%or more in time.

1. What color is good for Shading nets?

There are many colors of Shading nets, such as black, white, green, blue, yellow, red, silver -gray, etc. So, what color is good for Shading nets?

The color of the Shading net is added in the process of making raw materials. At present, the shade net sold on the market is mainly black and silver -gray. The Shading net color should be selected according to the type of vegetable types.

The black Shading mesh is high and the cooling rate is fast, but it has a greater impact on photosynthesis. It is more suitable for use on leafy vegetables. If used on some happy vegetables, the coverage time should be reduced;It has a small impact on photosynthesis and is suitable for eloquent vegetables such as eggplant fruits.

2. Why is the Shading net black

Black Shading net is a very suitable Shading Tool for vegetables that need light. This is because black is weaker than any color reflecting Solar light, that is, the ability to absorb sunlight is the strongest.When the sunlight transversed from the Shading net, the energy (thermal energy) of the Solar light has been consumed, and the following is naturally cool.So it is very suitable for the growth of crops.What we have seen on the market currentlyShading netMost of them have two colors, one is black and the other is gray, and the black effect is also a wider range. The gray ability is not black, so it is generally used on the crops of Xiguang.
