| 摘 要： | 目的]分析不同栽培密度对皖油29(Brassica napus L.)经济性状、产量和品质的影响,为提高油菜产量寻求科学种植依据。方法]采用随机区组设计,设置10个栽培密度处理,分别为12.0万、19.5万、27.0万、34.5万、42.0万、49.5万、57.0万、64.5万、72.0万、79.5万株/hm2。结果]栽培密度对千粒重,单株产量和单株角果数的影响较大,处理间差异达显著水平;栽培密度为42.0万株/hm2时,产量最高;含油量随着栽培密度增加先增后降。结论]直播油菜适宜栽培密度在34.5万～64.5万株/hm2为宜。

| Abstract: | Objective] The purpose was to analyze the effects of different planting density on economic characteristics,yield and quality of Wanyou 29,and find out a scientific planting basis for improving its yield.Method] The randomized block design was used in the test.10 planting density were 12.0×104,19.5×104,27.0×104,34.5×104,42.0×104,49.5×104,57.0×104,64.5×104,72.0×104,79.5×104 plants per ha resp..Result] Planting density had big effects on 1 000-grain weight,yield per plant and pod number per plant,and there were significant difference among 10 treatments.Thereinto,when planting density was 42.0×104,its yield was the highest.Its oil content firstly increased then decreased with planting density rising.Conclusion] The suitable planting density of rapeseed sowing directly was 34.5×104-64.5×104 per ha. |
