种植方式对麦套中早熟直播棉棉铃发育的影响

Effects of Planting patterns on Cotton Boll Development in Directly Sowed Cotton with Early-Mid Maturity in Wheat Field

研究结果表明，３—２式棉纤维发育早于３—１式，３—２式棉子（仁）脂肪和蛋白质累积明显优于３—１式，晚播极不利于３—１式脂肪和蛋白质的累积。种植方式对中早熟直播棉棉铃发育的影响小于播期作用。

Fiber development under 3-2 planting pattern (3 rows of wheat and 1 row of cotton) was earlier than that of 3-1. The response of fat and protein accumulation in seed (kernal) under different planting patterns were not significant, among which 3-2 pattern was better than that of 3-1 pattern, but it was no good for the accumulation of fat and protein of seed (kernel) when sowed late. Planting patterns had less effect compared to sowing date. Under the different field planting patters, when sowing at the normal time, the early middle maturity varieties.
