为考察玉米全膜覆盖技术在半干旱地区的增产能力,集成技术规范,采用小区试验与大田示范同步走的方法,在渭北旱塬丘陵沟壑区的麟游县开展了春玉米全膜覆盖技术增产增收效果、增产机理及栽培技术研究。春玉米全膜覆盖技术能够适应渭北丘陵沟壑半干旱地区的土壤、气候、耕作条件,较传统的露地栽培、半膜覆盖增产效果明显。半干旱地区推广玉米全膜覆盖技术,要落实好适期早播、精细整地、机械作业3个关键措施和良种应用、合理密植、配方施肥、病虫防治、化控防倒、后期揭膜6项配套技术。
In order to investigate the yield-increasing ability of maize full-film mulching technology in semi-arid area, integrate the technical specifications and adopt the method of plots experiment and field demonstration to walk synchronously, the spring maize whole-mulching technique was carried out in Linyou County in the hilly and gully region of Weibei highland Study on the Effect of Increasing Output and Increasing Yield, Yield Mechanism and Cultivation Techniques. The full-mantle spring mulching technology can adapt to the soil, climate and farming conditions in the semi-arid area of the hilly and gully area of Weibei. Compared with the traditional open field cultivation, the semi-film mulching has a significant yield increase effect. Semi-arid areas to promote corn full film coverage technology, we must implement the appropriate early sowing, fine preparation, mechanical operation of three key measures and the application of seed, reasonable close planting, formula fertilization, pest control, chemical control down, late uncover 6 Item supporting technology.
