Last Updated: 2024/11/22, Corn is a high-yield crop, which requires a large amount of fertilizer and is also sensitive to medium and trace element fertilizers. Reasonable fertilization is necessary to meet the nutrient needs of corn in the whole growth period. According to the experiment, the production of 100 kg corn seed requires 2.5 kg of nitrogen, 1 kg of phosphorus and 2.1 kg of potassium. If you yield 500 kg of corn per mu, you need urea 3 per mu.

Technical introduction: this technology is an advanced agricultural farming technology, through the implementation of no-tillage application of straw to cover the surface, reduce soil wind erosion, water erosion, and improve soil fertility and drought resistance. Core technology: ① straw mulching technology, straw and stubble left on the ground after corn harvest as mulch to reduce soil erosion and restrain sand blowing; ② no-tillage fertilization and sowing technology, using no-tillage seeder to fertilize and sow directly on uncultivated farmland; ③ chemical weeding technology, adopting soil closure after sowing and directional weeding. ④ deep loosening technology, conservation tillage mainly depends on crop roots and earthworms and other biological loosening, but because the mechanical work compacts the ground, the soil needs to be loosened, generally using special machinery once every 3-4 years. Ecological benefits: reduce surface runoff by 60%, soil water erosion by 80%, reduce wind erosion by 60%, reduce air pollution by not burning straw, increase soil water storage by 14-15%, increase water use efficiency by 15-17%, increase soil fertility, increase soil organic matter by 0.03%, and effectively restrain sandstorms. Economic benefits: reduce production costs; increase corn output by 5-13%; increase income by 8-15%. Social benefits: reduce the working procedure of agricultural machinery, reduce the labor intensity, and improve the quality of life of farmers.
