玉米集“粮、经、果、饲、能”等用途于一体,在河北省种植区域最广、面积最大、产量最高。但在高原雨养旱作区、平原的地下水压采区受水资源稀缺的限制,玉米产量很难达到预计的要求。因此,就必须通过一些节水栽培技术来实现提高玉米产量的目的。一、技术核心 Corn set “grain, by, fruit, feeding, can ” and other purposes in one, the most widely planted area in Hebei Province, the largest area, the highest yield. However, in the plateau rain and drought-relief area, the groundwater pressure mining area in the plain is limited by the scarce water resources, and the yield of corn is difficult to meet the expected requirements. Therefore, we must through some water-saving cultivation techniques to achieve the purpose of raising corn yield. First, the core technology
