种植密度对新葵18号生长发育及产量品质的影响
Effect of Planting Density on the Growth, Yield Quality of Xinkui No.18
摘要
Abstract
[Objective]By studying the dry matter accumulation, leaf area, leaf area index, yield and oil-content of Xinkui No. 18 under different planting density, the effect of planting density on the growth, yield and quality of Xinkui No . 18 were analyzed . [Method] The study was conducted to investigate the growth data of Xinkui No . 18 and calculate dry matter accumulation ,leaf area, leaf area index and yield under different planting density,then measure its oil - content. [ Result]The result showed that planting density has obvious effect on the growth of Xinkui No.18. Low density treatment (4 000 plant/667 1112) has higher single plant leaf area. High density treatment (5 500 plant/667 m2) has higher leaf area index. Treatment 5 000 plants/667 m2 has the highest yield,oil- content and dry matter accumulation per area. With the density increase, yield increased first and then decreased.[Condusion]Appropriate density could regulate the growth of individual plant of Xinkui No. 18. In Xinjiang,5 000 plant/667 m2 is the appropriate planting density, under which high yield and quality could be obtained .关键词
