Effects of Different Planing Density on Economic Characteristics,Yield and Quality of Rapeseed Variety Wanyou 29(Brassica napus L.)
摘要
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×l04, 34.5 ×104, 42.0×l04, 49.5 × 104, 57.0×l04,64.5 ×104, 72.0×104, 79.5 X 10 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 42.0×10, 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.关键词
