不同定植密度对淮安红椒生长发育及产量的影响

Effects of Different Plant Densities on Growth and Yield of Huai'an Red Pepper

研究了不同定植密度对淮安红椒超越2009生长发育及产量的影响。试验结果表明,较低的定植密度有利于淮安红椒叶片鲜质量、单果质量增加,定植密度对产量的影响可能主要是通过影响单果质量而实现,定植密度52 500株/hm2和60 000株/hm2处理,单位面积产量较其他密度处理显著增加。综合分析认为,红椒超越2009定植密度以52 500~60 000株/hm2较适宜,其中52 500株/hm2最好,红椒单果质量最大、产量较高。

We investigated the effects of different plant densities on the growth and yield of Huai＇an red pepper euhivar Chaoyue 2009. The results showed that, the lower plant densities were helpful to the increase of fresh leaf weight and single fruit weight of Chaoyue 2009, and the effect of plant density on yield was mainly achieved by influencing single fruit weight. When the plant densities were 52 500 and 60 000 plants/hm^2, the yields of Chaoyue 2009 were significantly higher than those of the other plant density treatments. Comprehensively, the suitable plant density for Chaoyue 2009 was 52 500-60 000 plants/hm^2, and the optimal plant density was 52 500 plants/hm^2, with the heaviest single fruit weight and higher yield.
