Special formula fertilizer for corn cultivation

Abstract

The invention relates to a special formula fertilizer for corn cultivation. The special formula fertilizer comprises KNO3 or KCl or K2SO4, Ca(H2PO4)2*H2O or KH2PO4, CO(NH2)2 or (NH4)2SO4 or 5Ca(NO3)2*NH4NO3*10H2O, MgSO4*7H2O or MgSO4*H2O, FeSO4*7H2O. Experiment results prove that compared with an existing conventional fertilization method (compound fertilizer, urea, diammonium phosphate, calcium superphosphate, monopotassium phosphate, ammonium sulfate, potassium chloride and potassium sulfate) for farmers, the special formula fertilizer for corn cultivation, provided by the invention, has the benefits that the use method is simple and convenient, plants robustly grow, the resistance to pests and diseases is realized, the frequency of spraying of pesticides is reduced, the pesticide and artificial spraying cost is reduced, the yield per mu can be improved by about 10 percent, the quality and the mouth feeling of corn is improved, and the original flavor of corn varieties is restored. The special formula fertilizer provided by the invention has very wide application values and market prospects.

Description

technical field

[0001] The invention relates to the technical field of large-scale agricultural production, and mainly relates to a special formula fertilizer for corn cultivation. Background technique

[0002] Corn is one of the most important food crops in my country. The annual corn planting area in China is 36.9 million hectares, and the output reaches 210 million tons. It is one of the three major food crops together with corn and wheat, and its output accounts for 1 / 3 of my country's food production. 3. Corn has extremely important economic value and social value. Its planting range covers most of my country's land. Because of its rich varieties and moderate growth period, it is suitable for planting in different areas such as mountainous areas, plateaus and plains. It is one of the main crops in most areas of our country. one. According to statistics, the world's corn production reaches 960 million tons, of which the United States' corn production is 340 million tons,...

Embodiment 1

[0042] When used as a base fertilizer, the fertilizer a) is applied to the furrows by machinery at the time of sowing corn seeds with the corn formula fertilizer at a rate of 25 kg per mu, and the seeds and the formula fertilizer particles are covered in the furrows by covering the soil at the same time. The depth of the soil covering is: About 3cm; when the corn seedlings grow to 40-50cm high, topdress the fertilizer once, and the amount of topdressing is about 25kg per mu. The amount of base fertilizer can be adjusted appropriately according to the soil conditions. If it is alkaline or acidic soil, the amount of base fertilizer should be appropriately increased to about 30kg. Topdressing can be carried out simultaneously with intertillage, that is, fertilization and soil cultivation while intertillage. The total amount of fertilizer used is 50-55kg / mu.

[0043] Specific method of topdressing: You can use machinery to spread evenly around corn seeds or corn seedlings and cov...

[0045] When used as a base fertilizer, the a) fertilizer is applied to the furrow by machinery at the time of planting the corn seeds with a fertilizer rate of 30 kg per mu, and the seeds and the formula fertilizer particles are covered in the furrow by covering the soil at the same time. The depth of the covering soil is About 3cm; when the corn seedlings grow to 40-50cm high, topdress the fertilizer once, and the amount of topdressing is about 25kg per mu. The amount of base fertilizer can be adjusted appropriately according to the soil conditions. If it is alkaline or acidic soil, the amount of base fertilizer should be appropriately increased to about 35kg. Topdressing can be carried out simultaneously with intertillage, that is, fertilization and soil cultivation while intertillage. The total amount of fertilizer used is 55-60kg / mu.
