- 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。
- Abstract:
- : In this study, taking watermelon-soybean intercropping system with wildly-use and apparent yield advantage in Northwest irrigation districts as the research object.A field experiment was conducted in five consecutive seasons (2011-2015), and investigated the influence of field population structure,including stripe pattern,different soybean varieties, sowing date and planting density, on the yield and economic return of intercropping of watermelon with soybean.The results showed that yields were the highest and economic returns were the maximum when the bandwidth was 160 cm, and the ratio of watermelon rows to soybean rows was 120∶40 cm.There was significant difference of soybean yield in different soybean varieties in watermelon/soybean intercropping systems, the yield of Qihuang 36, Jidou 12 and Longhuang 2 soybean varieties were higher than other varieties. Under the bandwidth with 160 cm (the ratio of watermelon rows to soybean rows was 120∶40 cm) of intercropping of watermelon with soybean Qihuang 36, the optimum planting density was from 1.5×104plants.ha-1to 1.8×104plants.ha-1. The optimum sowing date was in late May. Experiments showed the population configuration effect on watermelon-soybean intercropping system and the mechanism of good harvest formed the technology system of high-yield of watermelon-soybean intercropping system whose core technology was colony configuration.
