研究结果表明：品种对铃重影响作用表现为中早熟品种大于中熟品种，中早熟品种棉纤维发育早于中熟品种。３∶１式直播中熟品种极不利于棉纤维发育。品种对棉籽（仁）脂肪累积影响表现为中早熟品种优于中熟品种，晚播对中熟品种棉籽（仁）脂肪累积影响大于中早熟品种。棉仁脂肪酸和氨基酸含量在品种间的差异因播期而异。３∶１式直播棉棉铃发育受播期影响大，生产上以中早熟品种为好。
The results showed that the effect of the varieties on the boll weight was that the middle-early maturing varieties were more than the middle maturing varieties, the middle-early maturing varieties were earlier than the middle maturing varieties. 3: 1 type live in cooked varieties is not conducive to cotton fiber development. The effect of varieties on cottonseed (kernel) fat accumulation was that the middle-early-maturing varieties were better than middle maturing varieties, and the late-sowing had more influence on the accumulation of cottonseed (kernel) fat than middle-maturing varieties. Cottonseed fatty acid and amino acid content differences among varieties vary with sowing date. 3: 1 broadcast cotton bollworm development affected by the broadcast, the production of medium-early maturing varieties as well.
