玉米高产栽培技术可归纳为六句话,就是“培肥地力,优良品种,增加密度,配方施肥,防病治虫,适当晚收”。具体技术要点如下:1、选地、整地玉米根系发达,适应性强,对土壤种类的要求不严格,肥地、瘦地均可种植。但玉米植株高大、根系多、分枝多,要从土壤中吸取大量的水分和养分,所以选地要选择土层深厚、质地适中、肥力较高、排水良好的地块,前茬要选用马铃薯茬、肥沃的玉米茬或未使用长残效除草剂的大豆茬。整地以秋整地为主,积极推行轮耕制度,实 High-yielding maize cultivation techniques can be summarized into six sentences, that is, “cultivating fertility, excellent varieties, increasing density, formulating and fertilizing, preventing diseases and pests, appropriate late closing.” Specific technical points are as follows: 1, the election, land preparation Corn developed root system, adaptability, the requirements of the soil species is not strict, fat, thin can be planted. However, tall corn plants, roots and more branches to learn from the soil to absorb large amounts of water and nutrients, so choose to choose a deep soil, medium texture, high fertility, well-drained plots, the former crop to use potato Stubble, fertile corn stubble or soybeans that do not use long-lasting herbicides. Soil preparation mainly in autumn and autumn, actively promote the rotation system, in fact
