Abstract
[Objective]The aim was to study the appropriate combination of sowing time and planting density of high-protein Summer Soybean Guodou5hao. [ Method]as the test materials,four sowing time and five planting density were designed,the effects of sowing time and planting density on grawth and development and yield of Guodou5hao were studied. [ Result] With the sowing time delaying,the yield of Guodou5hao was decreased , while with the planting density increasing, its yield increasea first and then reduced. The effects of planting density on their pods and yield of Guodou5hao were bigger than that of sowing time. When planting in 5th June and planting density was 2.55 X 101 plant/hm2 ,the yield was the highest of 3 173.7 kg/hm2 . [ Conclusion] Under the permitting conditions,Guodou5hao should be sowing early and the suitable sowing time is 5th 12th June, the optimum planting density is 2.25 x 105 ~ 2.55 x 105 plant/hm2. If the sowing time is putting off, the planting density should be increasea.关键词
