1981年以来,我省对麦、豆、薯为代表的旱地三熟制在田间配置方式上,进行了条带式间套布局与传统的前后作物相互交叠生长的老三熟的定点比较试验,至1985年的结果表明,五年平均年亩产原粮增加407.8斤、产值增加47.16元,增长率分别为34.9和25％。改革后旱地的新多熟制,虽改变了老三熟三季产量“二头低”的被动局面,收到了显著的经济效益,但现行的带状间套复种,仍有若干缺陷。对此,原农业厅粮食生产处从1982年
Since 1981, the province has done a field trial on three-cropping systems of dry land represented by wheat, beans and potatoes, and compared the fixed-point experiments of the old third generation with the overlapping arrangement of the strip-type intercropping with the traditional pre- and post-crop The result of 1985 shows that the average annual output of mu produce per month increased by 407.8 kg in five years and the output value increased by 47.16 yuan with a growth rate of 34.9 and 25% respectively. After the reform, the new multi-cropping system of dry land has received significant economic benefits though it has changed the passive situation of the “low head” of the second trimester of the third generation. However, there are still some shortcomings in current multi-layer interplanting. In response, the original Agriculture Department Grain Production Office from 1982
