木薯与大豆间套种模式研究与效益分析

以华南205木薯和桂早2号大豆为试材,以不同模式进行间套种,通过对其农艺性状、产量以及试验地土壤养分进行测定分析,研究不同间套种模式对木薯与大豆生长发育、产量以及土壤理化性状的影响,并进行经济效益分析。结果表明:不同的间套种模式对木薯和大豆的生长发育及产量具有明显的影响,并能显著降低土壤容重,改善土壤结构;在固定的木薯种植规格下,以每畦2行木薯间种3行大豆的模式的纯收入最高。

Study on models of cassava intercropped soybean and its economic benefits analysis

Cassava of Huanan 205 and soybean of Guizao 2 were interplanted as testing materials in different modes. The effects of different intercrop models on growing development, yield, physic and chemical properties of cassava and soybean were studied through determing its agronomic characters, yield and soil nutrients, its economic benefits were also analysed. The results showed that there were noticealbe effects on the growing development and yiels of cassava and soybean in different intercrop models. The intercrop could reduce soil bulk density as well as improve soil structure. The model C, 3 rows soybean intercropped 2 rows of cassava of every border check, had the higest net income.
