秸秆覆盖还田技术是保护性耕作的关键技术措施,促进了农业节水、节本、增产、增效、环保和可持续发展。2011年山西省临汾市秸秆覆盖还田面积达到8万hm2(120万亩),平均提高粮食产量10%～15%,降低生产成本225～300元/hm2(15～20元/亩),有效地防止了农作物秸秆焚烧废弃,改善了生态环境,减轻了农民负担,增加了农民收益。
The technology of straw mulching and returning to the field is the key technical measure of conservation tillage, which has promoted the agricultural water saving, cost saving, production increase, efficiency increasing, environmental protection and sustainable development. In 2011, the coverage of straw mulching in Linfen City of Shanxi Province reached 80,000 hm2 (120 million mu), which increased the grain yield by 10-15% on average and reduced the production cost by 225-300 yuan / hm2 (15-20 yuan / mu). To prevent the burning of crop straw burning, improve the ecological environment, reduce the burden on farmers and increase farmers’ income.
