河西走廊孜然套种大豆密度试验

Study on Density Test of Cumin Interplanting Soybean in Hexi Corridor

以大豆品种中黄30号和孜然品种新抗18-2为材料,在河西灌区进行了孜然套种大豆密度试验研究。结果表明,当套种总带幅为160 cm,大豆带幅80 cm种3行,行株距30 cm×20 cm;孜然带幅80 cm,撒播密度为225.0万株/hm2时优势最明显,带田总产量可达9 478.8 kg/hm2,较对照增产8.8%,产值和纯收益分别为54 351元/hm2和48 921元/hm2,较对照增加10.7%和12.10%,且稳定系数高,为最佳套种密度。

The cumin-soybean intercropping pattern was studied by using soybean variety Zhonghuang 30 and cumin variety Xinkang 18-2 in Hexi Irrigation Areas.The results showed that the 160 cm belts,three rows for soybean in 80 cm belt,the row and plant spacing was 30 cm×20 cm,and for cumin 80 cm belt 2 250 thousand cumin plants per hm2 was the best interplanting pattern.The strip intercropping total yield was 9 478.8 kg/hm2 and 8.8% higher than of the check,the output value and net income were 54 351,48 921 yuan/hm2 and 10.7%,8.8% higher than of the check.The stability coefficient was high,it was the most optimum interplanting density.
