Reasonable fertilization is the basis for high yield of wheat. Only the various fertilizers, trace elements and microbial agents required for wheat can be matched to achieve high yield and stable yield of wheat. In order to produce high yields of wheat, it is necessary to apply a comprehensive and balanced fertilization. In addition to the commonly used NPK fertilizers, trace elements and micro-organisms are also very important.
First, NPK fertilizer
More than 1000 kg of wheat per mu, the bottom fertilizer needs 4-5 kg ​​of pure nitrogen (10 kg of urea), 7-9 kg of pure phosphorus (50 kg of ordinary phosphate fertilizer), and 3-4 kg of potassium fertilizer (6 kg of potassium chloride) Or the same amount of compound fertilizer 50-60 kg or so. Fertilization is based on the principle of applying the base fertilizer, returning to the green and controlling the fertilizer, and applying the joint fertilizer. Except for one-third of the total amount of nitrogen fertilizer for the whole year, other fertilizers were applied at this time.
Second, trace elements
Nowadays, wheat and wheat fields in Hebei Province are generally lacking trace elements such as boron and zinc. Boron can prevent wheat wheat ears from emptying and promoting grain fullness. Zinc can prevent wheat yellow dwarf disease, promote wheat straw wall thickness and toughness, and prevent wheat from lodging. It is necessary to add boron and zinc fertilizers to the base. It can be used for 200 grams of excellent borosilicate produced by American Borax Group or 150 grams of Ciba Boron and Zinc fertilizer produced by Swiss Ciba Company. It can be directly stirred into the compound fertilizer and evenly spread to the ground. In the case, each mu of land can increase the yield of more than 100 kg of wheat.
Third, microbial agents
Repeated planting in successive years will cause soil compaction and harmful bacteria to multiply, causing serious diseases such as total erosion, sheath blight and root rot, resulting in severe wheat yield reduction. It can be used to spread 150 grams of micro-producing bacteria per acre or 4 kilograms of Jiayuan heavy-duty agent. This is a guarantee to reduce the disease and make the wheat high-yield.
