● Corn varieties. Corn has no strict requirements on soil, but fertile and loose sandy loam or Humus loam is preferred. In winter and spring, it is necessary to dig deep and apply sufficient base fertilizer. The amount of fertilizer required for corn is 15-2 kilograms of ternary compound fertilizer per mu, and 1-2 kilograms of phosphorus fertilizer per mu, each accounting for 1-2 kilograms; Pay attention to the uniform proportion of phosphorus and potassium fertilizers when topdressing, and increase the yield of corn by about 20% in the county.

Complementary according to plant traits. If for a long time, it is necessary to sparse and classify. Combine the grow trend of the plant or choose to stay. If the adult plant is prosperous, fertilization can be applied in stages, and more can be left (in the box), but not more (/) to avoid damaging the homogeneity. Can be calculated. Generally, 2667-2000 plants are used per mu, and the total amount of phosphorus fertilizer is 100000 to 130000 kilograms per mu.

For every 20 kilograms harvested, potassium fertilizer is sprayed on the leaves to facilitate rapid expansion of the fruit. After fertilization, the booting ears should be loosened and pulled out immediately. The high sugar content (10% -20% tuberculin 30~) can be selected, and the high efficiency anti falling pesticide can be added. If possible, other pesticides can be selected for spray.
