浙中西部植棉区棉花适宜播种期探讨

Explore the Suitable Sowing Date of Cotton in Cotton Planting Area of Zhejiang Midwest

为了探索推迟播种对棉花产量及效益的影响,以湘杂棉8号为供试品种,在浙江中西部植棉区开展了不同播期对棉花生育期和产量影响的试验。结果表明:浙江中西部植棉区棉花可以延迟到6月下旬播种,以高产为目标的适宜播种期是4月下旬至5月上旬,不宜迟于6月底。

In order to explore the effect of delayed sowing on cotton yield and benefit,the influence of different seedtime on cotton growth period and yield was tested,using Xiangzamian No.8 as experimental materials,in cotton planting area of Zhejiang Midwest. The results showed that the last sowing date in cotton planting area of Zhejiang Midwest could be reaching late June,the suitable seedtime for high yield was from late April to early June and shoud not be later than the end of June.
