Fertilization skills for vegetables and fruit trees to promote production!

Crop fertilization plays a vital role in crop growth. How to fertilize correctly and effectively is a concern of many growers and fruit growers. Today, we have summarized some fertilization skills about fruit trees and vegetables. I hope it can help you!

Phosphate fertilizer as base fertilizer

Phosphorus is easily fixed in the soil to become ineffective phosphorus, so the base fertilizer should be applied together with organic fertilizer and should not be used as topdressing.

The application of micro-fertilizer should be targeted

Different crops have different requirements and sensitivity to different trace elements, and the effect of application is also different. Therefore, in the application, we should determine the type and quantity of micro-fertilizer according to the specific types of crops. For example, rape is sensitive to boron, legume crops are sensitive to boron and molybdenum and so on.

Cake fertilizer should be combined with other fertilizers.

Cake fertilizer is rich in kinds and contents of nutrients, but it can not fully meet the growth requirements of vegetables, so it should be applied in combination with other fertilizers. The mixed application of topdressing with high potassium compound fertilizer can promote crop growth, and the mixed application of base fertilizer and chicken manure can improve the fertilizer efficiency.

Be cautious in purchasing imported water-soluble fertilizer

There are many water-soluble fertilizers labeled "imported" on the market are domestic, but sell at high prices under the banner of import. When buying, be sure to carefully check the manufacturer, address, registration certificate number, implementation standards, etc., if necessary, you can search the information of the fertilizer online.

Nitrogen fertilizer for fruit trees should be applied in autumn

After absorbing nitrogen fertilizer, fruit trees have to go through a series of transformation and synthesis before they can be stored in the tree. It will take some time. If it is applied in spring, it will not have an effect on flowering and fruiting, flower bud differentiation, etc., so it is best to apply it before the leaves of fruit trees fall in autumn.

Do not apply nitrogen fertilizer blindly

Crops have a great demand for nitrogen fertilizer, and many farmers will apply a large amount of nitrogen fertilizer to crops, which is likely to lead to fertilizer damage and crop nitrate accumulation.

Combined application of organic fertilizer and chemical fertilizer

The combined application of organic fertilizer and chemical fertilizer can promote each other, which can fully ensure the nutritional supplement in the whole period of crop growth and development and effectively improve crop yield.

Ammonium bicarbonate should be preserved reasonably

The stability of ammonium bicarbonate is poor, and it can be completely decomposed at atmospheric pressure when the temperature reaches 70 ℃. It is easy to absorb water to dissolve and agglomerate in a humid environment, and corresponding measures should be taken to prevent its volatilization loss during storage.

Ammonium Chloride should be used cautiously

Ammonium chloride should not be applied in acid soil, saline-alkali soil and chlorine-avoiding crops, and should not be used as seed fertilizer. Chloride ion has a certain inhibitory effect on nitrifying bacteria, and the nitrification leaching effect of nitrogen applied to soil is weaker than that of other nitrogen fertilizers.

Different potash fertilizers should be applied together.

Potassium sulfate should be selected for tobacco, sugar crops and fruit trees, potassium chloride for fiber crops, potassium sulfate for efficient cash crops, and potassium chloride for general field crops except a few crops that are sensitive to chlorine, which is relatively cheap.
