以西北一熟制灌区当前生产中广泛种植且间套作优势明显的西瓜/大豆套作方式为研究对象,通过5年田间试验,对影响该复合群体产量及效益的带幅比、品种、密度及播期4个主要群体配置因子进行系统的试验研究。结果表明:带幅1.6 m,西瓜、大豆带幅比1.2/0.4模式为西瓜套作大豆最优带幅配置;不同熟期大豆品种套作西瓜,大豆产量差异达到显著水平,齐黄36、冀豆12和陇黄2号产量显著高于其它品种;带幅1.6 m,西瓜、大豆带幅比1.2/0.4模式下,大豆品种齐黄36适宜密度为15万~18万株·hm-2,适宜播期在5月下旬。
In the current production of the northwest one-cropping irrigation area, the widely planted and intercropped watermelon / soybean intercropping system with obvious advantages was selected as the research object. Through field experiment in five years, the yield, And sowing time of 4 major groups configuration factors for systematic experimental study. The results showed that the optimum width and breadth of watermelon and soybean were 1.2 m and 0.4 m, respectively. The yield of soybean and soybean reached the significant level at different mature soybean cultivars. Qihuang 36 and Ji The yield of Beans 12 and Longhuang 2 was significantly higher than that of other varieties. When the width was 1.6 m and the watermelon and soybean ratio was 1.2 / 0.4, the appropriate density of soybean variety Qihuang 36 was 150,000-180,000 hm-2, Suitable for sowing in late May.
