密度对大豆群体碳氮代谢相关指标及产量、品质的影响
Effect of plant density on soybean carbon and nitrogen metabolism, yield and quality
摘要
Abstract
Effects of plant density on carbon and nitrogen metabolism, yield and quality of soybean cultivar Kennong 4 were investigated in field. The results showed that nitrogen, soluble protein, starch and cane sugar accumulation increased gradually with the increase of plant density, and there was significant difference among different density of soybean populations; With the increase of density, the proten content in soybean seed increased but fat content decreased;Through analyzing correlation at each stage, we known that there was a negative correlation among nitrogen, soluble protein, starch and cane sugar accumulation and proten content, and a positive correlation with fat content; The pod number, seed number and seed weight went higher when the density got smaller, and the yield of 3.6 × lO5-plants-per-hm2 reached to the highest.关键词
