不同密度对滴灌红籽瓜产量及相关性状的影响

通过对滴灌红籽瓜不同密度对比试验寻找其适合大型机械化作业的最佳密度，从而进一步探讨红籽瓜高产栽培技术，为指导大田生产服务。采用扩大行距，对留苗方式进行必要的调整，分别对3700、5550、7400株/667m²三种密度做了小区试验。结果以5550株/667m²取得了较高的产量和较好的品质。在此密度下单产达147.8 kg，达极显著水平。总结出适合新疆昌吉地区红籽瓜高产栽培的最佳密度为5550株/667 m²，其产量、植株生长、主要经济性状、干物质积累为最佳。

Effect of different density on yield and characteristic with drip irrigation of red-seed melon

The field research was conducted to study the optimum density for large-scale mechanized operations, and to obtain high yield cultivation techniques of red-seed watermelon in field production. The experiments used a factorial arrangement of different density 3700, 5550, 7400 per 667 m2 with expansion of row. The yield and quality was highest with density of 5550 per 667 ms, its yield reached 147.8 kg/667 m2, and was significantly different from other treatments. Therefore, the optimum density for red-seed watermelon was 5550 per 667 ms in Changji area, and its growth, the main economic character, yield, dry matter accumulation was the best.
