试验于1987～1988年在西北农业大学农作一站盆栽试验场进行,供试品种为秦棉一号,试验以土壤含水量占土壤最大持水量的百分比为标准,设6个处理,10次重复。研究了土壤水分对棉籽发育的影响。结果表明,土壤湿度对种子体积增长、干物质积累、种子蛋白质和脂肪含量有明显影响。当土壤湿度为40%时,棉籽发育慢,日增长量 The experiment was carried out in 1987-1988 at the one-station pot experiment station for farming in Northwestern Agricultural University. The test variety was QMM1. Based on the percentage of soil water content to the maximum water holding capacity of soil, the experiment was divided into 6 treatments, 10 times repeat. The effect of soil moisture on cottonseed development was studied. The results showed that soil moisture significantly affected seed volume, dry matter accumulation, seed protein and fat content. When soil moisture is 40%, cottonseed grows slowly and daily
