机械化栽培,可以提高生产效率,省工省力,提高作业质量,保证作业时间。秋翻地,能疏松土壤,改善土壤理化性状,将根茬、粉碎后的秸秆直接埋在地里,有利于提高土壤有机质,消灭病虫草害。秋耙地,土壤细碎,减少蒸发,蓄水保墒,春旱秋抗。机械播种,不翻乱土层,避免干湿土结合,利于抢墒,且覆土深浅一致,施肥均匀,株距相等,节省种子,降低成本,苗齐,苗壮。玉米杂交种制种机械化栽培,应主要做好以下几点:1 精细整地
Mechanized cultivation, can improve production efficiency, save labor and labor, improve job quality, ensure the operation time. Autumn fall, can loosen the soil, improve soil physical and chemical properties, stubble, crushed straw directly buried in the ground, help to improve soil organic matter, eliminate pests and diseases. Autumn harrow, soil crushing, reduce evaporation, water and soil moisture, autumn and drought resistance spring. Mechanical sowing, do not upset the soil, to avoid the combination of dry and wet soil, which will help grab moisture, and cover the same depth of soil, fertilizer evenly, spacing is equal, save seeds, reduce costs, Miao Qi, Miao Zhuang. Maize hybrid seed production of mechanized cultivation should be mainly done the following: 1 fine preparation
