通过1987～1990年稻田粮经型新复种方式对比试验结果,表明了新复种方式“大麦/西瓜+玉米-稻”和“绿肥+大麦/西瓜-稻”分别比原复种方式”大麦/西瓜-稻”和“西瓜-稻”亩增粮食99.2和296.2 kg,增收25.11元和49.93元,提高光能利用率0.145％和0.596％。同时,分析了水、旱作茬口对晚稻的增产后效。
The results of the comparison of the new cropping patterns of paddy field and grain-type in 1987 ~ 1990 show that the new double-cropping patterns “barley / watermelon + corn-paddy” and “green manure + barley / watermelon- Rice ”and“ watermelon - rice ”increased by 99.2 and 296.2 kg mu, increased by 25.11 yuan and 49.93 yuan, and improved the utilization of light energy by 0.145% and 0.596% respectively.
