玉米产量的高低主要取决于种子、栽培技术、管理方式等。推广良种+化除+矮壮素+叶面肥+杀虫(菌)剂+测土配方施肥+育苗移栽或地膜栽培的种植模式是获得高产的重要措施。近年来,由于青壮年外出打工的较多,在农村出现劳动力不足的现象,这一模式的推广可节省劳力、抵御风灾、防病防虫,从而实现玉米高产低耗,提高单产,增加种植效益。1选用良种良种是玉米高产技术的核心,所以要因地制宜选用适宜当地的杂交优良品种,最好选用本省生产的良种。2精细整地前茬作物(绿肥、小麦、油菜、青稞等)收获后视墒情深犁一次,将石块捡
The level of corn production depends mainly on the seeds, cultivation techniques, management methods. Popularization of advanced varieties + addition + CC + foliar + insecticide (bacteria) agent + soil testing and fertilizer + seedling transplanting or film cultivation planting mode is an important measure to obtain high yield. In recent years, due to the large number of young and middle-aged migrant workers who go out to work in rural areas, there is a shortage of labor force. This mode of promotion can save labor, resist wind and pest control and prevent insects, so as to realize high yield and low consumption of corn, increase yield and increase planting benefit. 1 Selection of elite varieties of high-yielding corn is the core technology, so to local conditions appropriate selection of local hybrid varieties, the best selection of the province’s production of improved varieties. 2 fine pre-stubble crop (green manure, wheat, rape, barley, etc.) after harvest as the deep plow moisture once, the stone pick
