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.
