Corn planting method based on fertilizer applying treatment and capable of effectively adjusting and controlling waterlogging stress

Abstract

The invention discloses a corn planting method based on fertilizer applying treatment and capable of effectively adjusting and controlling waterlogging stress. The corn planting method comprises the following steps of performing fine soil preparation before sowing, and holding soil moisture; performing sowing in June, wherein the planting density is 67500 plants / hm<2>, according to the yield level of 12000kg / hm<2>, applying 210kg / hm<2> of N, 84kg / hm<2> of P2O5 and 168kg / hm<2> of K2O, and before the N, the P2O5 and the K2O are applied, uniformly mixing the N, the P2O5, the K2O and nitrapyrin (2-chloro-6-trichloromethylpyridine, nitrapyrin) for accompanying applying; separately applying 40% of nitrogenous fertilizers at a jointing stage and 60% of the nitrogenous fertilizers at a large trumpet stage, and applying all phosphate fertilizers and potash fertilizers once before sowing; performing furrowing at positions of 10-15cm away from corn planting rows for applying fertilizers; and performing field management according to the level of high-yield fields. After the fields are flooded in water, topdressing of urea with the nitrapyrin is performed, so that notable increase of yield is facilitated.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a corn planting method for effectively regulating and controlling waterlogging stress based on fertilization treatment. Background technique [0002] Waterlogging is a major natural disaster faced by many countries around the world. According to statistics, the global arable land area affected by flood disasters is about 12% of the total arable land area. Waterlogging affects or even destroys the growth and development of crops to a large extent, reducing yield. As far as our country is concerned, the middle and lower reaches of the Yangtze River and the Huanghuaihai Plain are the most affected, accounting for more than 3 / 4 of the total disaster-affected area in the country. Precipitation in the Huang-Huai-Hai region is mostly concentrated during the growing season of summer corn, which often causes water accumulation in the farmland, leading to corn waterlogging. ...

AI Technical Summary

Problems solved by technology

The application of biochemical agents is costly and labor-intensive, and individual biochemical agents may have adverse effects on the environment; topdressing or spraying nitrogen fertilizers after waterlogging stress increases the use of nitrogen fertilizers, increases the workload, and the additional application of nitrogen fertilizers It may cause damage to the soil environment, which violates the national policy of zero growth in fertilizer consumption
