不同密度麦后直播棉生育特性与经济效益分析

Analysis on Growth Characteristics and Economic Efficiency of Direct-sowed Cotton after Wheat with Different Density

通过麦后直播棉不同密度试验及其与麦套棉经济效益的对比分析,初步探明麦后直播棉的生长发育规律,筛选出麦后直播棉适宜的种植密度为9.0万株/hm2,此密度下产量可达3 738.0 kg/hm2;麦后直播棉经济效益优于传统麦套棉。

Through the experiments of direct-sowed cotton after wheat with diff6rent density, and the comparative analysis of the economic efficiency between direct-sowed cotton after wheat and transplanted cotton interplanted with wheat, the growth characteristics of direct-sowed cotton after wheat were preliminarily studied. Test results showed that the suitable density was 90 000 plants/hm2 with the maximum yield reached to 3 738.0 kg/hm2. The economic efficiency of direct-sowed cotton after wheat was better than transplanted cotton interplanted with wheat.
