川中丘陵区经济林粮立体种植模式与效益研究

Research for the Stereo-planting Model of the Economic Fruit-grain in the Hilly Area of the Middle of Sichuan and Its Benefits

以川中丘陵区的遂宁市市中区为试验基点，研究在满足人口最高峰值时对粮食需求的基础上，开发适度比例种植纯粮的坡耕地为经济林粮立体种植。对挑粮、桔粮、油粮、桑粮四种不同经济林粮立体种植模式，研究其实用技术，以及不同经济林粮立体种植模式与纯粮常规种植的效益比较。通过实测资料的分析评价，无论是生态效益，经济效益及水土保持的综合效益都十分显著。

Taking Suining urban district. one part of the hilly land in the middle of Sichuan,as an experimental plot, on the basis of studying the demands for cereals to satisfy the most booming population, we can develop some hillside cultivated land planting single cereals into three-dimensional planting of economic fruit-grain, the stereo-planting models of the four different economic fruit-grain are peaches-grain, oranges-grain shaddocks-grain and mulberries grain. Practical skills have been studied and the benefits from different stereo-planting model of economic fruit-grain have been compared with the benefits from single cereals planting. The experimental data have been analyzed and evaluated, ecological, economic and comprehensive benefits from water and soil conservation are very notable.
