低丘红壤坡地柑桔──花生立体复合体系效益的研究

Study on the Benefit of the Orange-Peanut Compound System in the Low Hilly Sloping Fields of Red Soil

本文着重探讨了低丘红壤坡地柑桔花生种植体系的生态与经济效益。果农复合体系在高温干旱期可降低土壤温度，增加土壤含水量，改善土壤理化性状，提高柑桔产量和改善品质。柑桔花生复合体系５年可回收全部投资，对照区６年仅收回投入的８１．３０％。

The ecological and economic benefits of the orange-peanut cultivation system in the low hilly sloping fileds of red soil were discussed in this paper. The compound fruits-crops system helped reduce soil temperatue, increase the content of soil water, improvesoil phyical and chemical properties, inmprove yield and quality of orange. All the investment was retrieved within five years in the compound orange-peanut system, while only 81.3% was retrieved within six years in the control system.
