1983年,我县绿肥免耕(实为少耕,下同)发展很快。据统计,全县绿肥免耕11920亩,占实种绿肥28655亩的41.5%,为上年绿肥免耕面积2000亩的5.9倍。为了深入了解绿肥免耕在不同条件下的潜在影响,进一步掌握绿肥免耕的种植技术,自一九八三年初以来,在县局和科委的领导、支持下,我们结合大面积生产,在全县范围内进行了多点试验示范和调查研究。秋收期间在6个区1个镇的19个点、23户人家、
In 1983, my county no-tillage of green manure (actually less tillage, the same below) developed rapidly. According to statistics, 11920 mu of no-till green manures are accounted for by the county, accounting for 41.5% of the 28,655 mu of real green manures and 5.9 times of the no-till manure area of 2000 mu in the previous year. In order to gain a deeper understanding of the potential impact of no-tillage on green manures under different conditions and further grasp the cultivation techniques of no-tillage manure, since the beginning of 1983, under the leadership and support of the county bureau and the science and technology commission, we have integrated large- County-wide multi-point pilot demonstration and investigation. During the autumn harvest in 19 districts of 6 towns and 1 town, 23 households,
