摘要
多年的研究和实践表明 :由于地膜小麦的增温、保墒效应 ,明显地改善了麦田的温、光、水、肥、气等生态条件 ,促进小麦个体生长发育 ,使小麦单位面积总穗数、穗粒数和千粒重明显增加 ,生育期缩短 ,有利于避开后期病、虫、干热风等自然灾害 ,大幅度提高小麦产量 ,是解决我国干旱半干旱地区小麦生长期缺水问题的关键性栽培技术措施之一。该项技术的研究与推广 ,打破了密植作物难以覆盖的禁区 ,是小麦栽培史上一次突破性的革命。
In China, the studies and practice results of wheat plastic film mulching cultivation techniques many years show:the soil synthesized and heating degree effect of plastic film mulch induce wheat root growing and tillering producing, add the total spike number of unit area, the number of grains per spike and the weight of ear seed, be favourable to insect pest hot air ect.,natural calamities in anaphase, raise largely the per unit yield.It is one of the dry cultivation technologies to deal with the question of water deprivation in wheat period of growth at arid and semiarid zone. The research and extension of the technology come over the preserve area of the close planting crop's film mulching, It is a important revolution in the history of wheat cultivate.
