Abstract
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.关键词
