为了彻底解决和消除废膜污染土壤的严重问题,昌古州农业科技开发中心1996年从专利厂家浙江宁波银光公司引进了银光降解膜分别在棉花、玉米、甜菜和豇豆上进行了试验,取得了比较理想的试验效果,现简介如下。(一)试验目的昌吉州近年来“三膜”(地膜棉花、玉米和甜菜)种植面积发展很快,其中地膜棉花48.77万亩,地膜玉米36.65万亩,地膜甜菜4.52万亩.另外还有地膜蔬菜11.15万亩,地膜西甜瓜4.56万亩,1996年又开始示范种植地膜小麦,为发展高产优质高效农业打下了良好的基础。在大力推广地膜栽培的同时,残膜污染,残膜回收已成为当务之急,它们阻断土壤水分运动,防碍作物根系下扎,影响作物根系对土壤水分、养分的吸收利用,造成缺苗、死苗而导致农作
In order to completely solve and eliminate the serious problem of soil polluted by waste film, Changzhou Agricultural Science and Technology Development Center in 1996 from the patented manufacturer Ningbo Yinuang Co., Ltd. introduced silver light-degrading film in cotton, corn, sugar beet and cowpea were tested, Achieved a more ideal test results, are as follows. (A) the purpose of the test Changji in recent years “three film ” (mulching cotton, corn and sugar beet) acreage developed rapidly, of which 487,700 acres of plastic film mulching, 366,500 acres of plastic mulching, mulching 4.52 acres of sugar beet. There are 111,500 acres of mulched vegetables and 45,600 acres of melons and melons. In 1996, demonstration of planting mulched wheat began to lay a good foundation for the development of high-yield, high-quality and high-efficiency agriculture. While vigorously promoting the cultivation of plastic film, residual film pollution, residual film recovery has become a top priority, they block the movement of soil moisture, hinder crop roots under the bar, affecting crop roots on soil moisture, nutrient absorption and utilization, resulting in lack of seedlings, dead Miao led to farming
