上海市青浦区全年粮油复种面积近40万亩。以前农作物的秸秆主要是用作燃料,随着农村生活水平的提高,秸秆燃料已被液化气所替代。所以,大田中80％的秸秆一烧了之,造成狼烟四起,污染空气,影响交通,使土壤表土焦化,降低了肥力,有时还引起火灾。为此,上海市对农作物秸秆采取了禁烧和机械化还田的措施,青浦区从1999年起,积极进行秸秆机械化还田技术的推广应用,三年来取得了较好成效。
Qingpu District, Shanghai annual grain and oil area of nearly 400,000 mu. In the past, the straw of crops was mainly used as fuel. With the improvement of rural living standards, straw fuel has been replaced by liquefied gas. Therefore, 80% of the stalks in the field are burned, causing the smoke and smoke to pollute the air, affecting traffic, causing the topsoil to coking, reducing fertility and sometimes causing fire. Therefore, Shanghai Municipality has adopted measures to ban burning and returning mechanized straw to crop stalks. Since 1999, Qingpu District has been actively promoting the application of straw mechanization to the fields and has achieved good results in the past three years.
