摘要
"八山一水一分田"准确指出福建耕地稀缺状况。占总耕地面积达45%的山区低产田和有限的灌溉条件严重制约着全省作物产量,对低产田的高效利用显得尤为关键。本试验选取玉米∥花生的间作方式,设置3∶6、3∶8、3∶10、3∶12等4种间作比例,在福建莆田大洋乡试验基地,借助生物的生态位关系及其原理,开展不同间作比例对间作系统种间关系的影响研究,探讨间作增产的机制,以期为福建红壤山区农业作物安排提供借鉴。试验结果表明:(1)相比单作,玉米与花生在适合比例下是可以取得不同程度的间作效益;(2)3∶8间作比例因具有最良好的种间竞争关系,表现出最大的竞争正效应和最高的资源利用率,因而其系统生产力最大,效益最高。
Fujian has 80% of its land covered by mountains,10% are under water,and only 10% are farmlands. Moreover,45% of the limited land for crop growth are in the hilly areas with low crop yields and scant irrigation, which invariably further hinders the farming activities.Therefore,a field experiment was conducted in rural Dayan of Putian city to explore feasible and ecological means for improvements.Four ratios on intercropping maize and peanut,i.e.,3∶6,3∶8,3∶10,and 3∶12,were tested.It was found that （1）all of the intercropping patterns brought about varying degrees of improvements over monoculture practices;and,（2）among the 4 designs,3 ∶ 8 （maize∶peanut）ratio showed the highest productivity and most benefits,rendering a maximized facilitation and complementation between the two crops,as well as the greatest utilization of natural resources.
