With the large-scale application of farmland fertilizers, soil compaction and fertility decline. In order to improve the soil fertility of the farmland, according to the yield standard and fertilizer characteristics of the crops grown in the farmland, as well as the fertilization efficiency of the soil and the characteristics of the fertilizer used, a specific fertilization scheme was developed through a special soil testing formula system software. Farmers can apply fertilizer according to the plan, and can maximize the rational use of fertilizer, balance the use of fertilizer, save fertilizer, and continuously improve the yield, quality and benefits of crops.
1. Deeply plowing deep pines to improve the soil environment. When deep ploughing and deep ploughing, it is advisable to apply organic fertilizer, and the depth of deep ploughing is 20-25 cm. If the ploughing does not reach depth or the clods are not fine, it is necessary to plow again to ensure the quality and effect of deep ploughing.
Second, the application of farmyard manure, rapid change of soil and fertilizer. Farmyard manure is an organic fertilizer with a wide range of raw materials, large quantities and full nutrients. It has a fast speed and good effect. The slang of “the soil is supported by manure and the seedlings are long†reflects the importance of farmyard manure to soil and crops.
Third, the straw returned to the field to improve the soil. Straw returning is one of the effective measures to improve soil fertility. By returning straw to the field, soil organic matter is increased, soil nutrients are reduced, soil porosity is increased, soil moisture is adjusted, and soil fertility is improved.
Fourth, soil testing formula to improve the level of fertilization. Soil testing and formula fertilization is a widely popular new fertilization technology. It is to collect soil samples from farmland tillage layers, and to measure the contents of a large number of nutrients and some trace elements in the soil such as alkali nitrogen, available phosphorus, available potassium, and effective boron and zinc.
