摘要
1994-1996年黑龙江省不同生态区大豆联合试验结果表明,不同生态区采取缓解的各项农艺措施均可(1)减少重、迎茬大豆的产量损失,使重茬产量损失较正茬降低在10%以内,迎茬产量接近正茬产量;(2)对重、迎茬大豆株高、叶面积指数、干物质积累均起到促进作用;(3)可减轻重迎茬大豆根部病虫害。
The results of soybean experiments conducted in three ecology areas in Heilongjiang province during 1994-1996 showed that: (1) Each agricultural measure could reduce the yield losses when soybean was planted continuously or following next crop. The soybean yield for continuous cropping was 10% lower than that of normal rotation. For soybean following next crop, the yield was close to the normal rotation. (2) The agricultural measrues could play the increment role to the soybean height,the leaf area index,the dry matter accumulation. (3) The agricultural measures could reduce the root disease and insect pest of soybean.
