１９９５～１９９６年分别在重茬条件下进行了不同耕作措施对大豆根腐病、生育与产量影响的研究。结果表明，重茬大豆连年间隔深松耙茬１９９５年、１９９６年分别较对照增产２１．２％、１６．２．％。大豆生育期间调查发现，间隔深松比翻地大豆根腐病减轻，大豆株高、茎粗、干物质积累增加，并使根数量增多。
The effects of different tillage practices on root rot, fertility and yield of soybean were studied under different cropping conditions from 1995 to 1996 respectively. The results showed that the deep-seeding stubble of successive cropping soybean increased 21.2% and 16.2% respectively over the control in 1995 and 1996 respectively. %. During the growth period of soybean, it was found that the interval subsoiling was less than the root rot of upland soybean, the plant height, stem diameter and dry matter accumulation increased and the number of roots increased.
