由山西省农科院玉米研究所研发的中国首台玉米膜侧播种机已在山西省忻州市正式投入田间示范作业。此举有效解决了高温导致玉米早衰、地膜回收难等问题,玉米产量显著提高。地膜覆盖作为最有效的抗旱技术在中国大面积推广,其以开沟铺膜后将玉米种于膜上为主要推 The first corn film seeding machine developed by the Institute of Maize in Shanxi Academy of Agricultural Sciences has formally put into field demonstration in Xinzhou, Shanxi Province. This solution effectively solves the problems of high temperature leading to premature corn failure, mulching and so on, corn yield increased significantly. As the most effective drought-resistant mulching technology, mulching has been popularized in China. The main method of planting mulching on the film after trenching
