玉米根茬机械粉碎直接还田技术,使刨、捞、搂和运茬子工序一次完成,是促进农业增产增收的技术措施。1991年,我县这项技术推广面积完成61万亩,占可还田面积的97.4%,使玉米在遭受灾害的情况下,仍然夺得了大丰收,取得了较好的经济效益、社会效益和生态效益。 1.经济效益 (1)增产效益玉米根茬机械粉碎还田能增加土壤有机质含量,改善土壤理化性能,提高土壤肥力,促进粮食增产。我们调查了大孤山镇柴家村王习志和五一乡西尖山村孟继富用机户。在其它条件相同的情况下,根茬用
Maize stubble mechanical crushing directly into the field of technology, the planing, fishing, hug and transport stubble sub-processes once completed, is to promote agricultural production and income technical measures. In 1991, 61 million mu of technology was popularized in this county, accounting for 97.4% of the total recoverable area, so that corn still won a great harvest in the event of a disaster and achieved good economic, social and social benefits Ecological Benefits. 1. Economic Benefits (1) increase yield corn stubble mechanical crushing can increase soil organic matter content, improve soil physical and chemical properties, improve soil fertility, and promote grain yield. We investigated Wang Jizhi, Chaijia Village, Dagushan Town, and Mengji Fu, the Xijian Village, Wuyi Township. In other conditions under the same circumstances, stubble use
