旱地多熟制的作物组合(组配)方式很多,但其经济收益大多不高。为寻求粮经兼顾经济效益好的作物组合方式,经反复试验,我们发现小麦西瓜红苕中厢分带轮作三熟制是较为理想的方式之一。该种植制的光能利用率、产量、经济收益都达到了较佳水平。年光能利用率1.65％,经济产量(干重)900公斤以上,经济收益可达1000元。因此很受农民欢迎。从1984年试验5亩开始,经全市农技干部考察推荐,到1987年已在江津县、长寿县、巴县发展2万多亩。现将该种
There are many ways to combine multiple cropping systems (grouping) in dry land, but most of the economic benefits are not high. In order to seek a combination of good grain-economy and good economic crop combinations, after repeated experiments, we found that the watermelon red-bellied in the car three-wheeled crop rotation system is one of the more ideal way. The planting system of light energy utilization, yield, economic returns have reached a better level. Annual energy utilization rate of 1.65%, economic output (dry weight) of 900 kg or more, the economic benefits of up to 1,000 yuan. So very popular with farmers. Starting from the test of 5 mu in 1984, it has been recommended by the city’s agricultural cadres that by 1987, 20,000 mu of land in Jiangjin County, Changshou County and Baxian County have been developed. Now that kind
