摘要
利用随机区组排列设计,在玉米与西瓜间作条件下,研究了稀穴密株种植对作物产量形成因素的影响。结果表明,稀穴密株种植能够协调降雨的不均衡性,增加补灌的人为可控制性,能够利用有限水源实现旱地稳产的目的。试验条件下,产量和经济效益最好的处理为M0W4P4500,立体种植效果最好的处理是M1W3P4500。
This paper studies on the effects of dense-planting in thin-hole technology on the composing factors of crop yield by randomized complete block design in the condition of corn-watermelon interplanting. The results show that dense-planting at thin-hole technology could regulate the imbalance of rainfall and increase controllable artificial irrigation by human. So that stable yield could be obtained by using limited water source. In this study, the optimum treatment for yield and economy efficiency was M0W4P4500. The best treatment of stereo-planting pattern was M1W3P4500.
