风化花岗岩水土流失区引种中华猕猴桃试验研究

Experimental Study on the Introduction of Chinese Actinidia in the Soil Loss Area of Weathered Granite

本文阐述了风化花岗岩水上流失区引种的中华猕猴桃的长势、产量、质量以及试验地的土壤改良情况,并对试验场地套种的经济作物及总的产出与投入进行系统分析。结果表明:该试验地五年平均每亩年投入533元,产出903元,产投比为169.3％;第五年每亩盈纯利1800余元。研究说明,在风化花岗岩水土流失区引种中华猕猴桃是可行的,效果是明显的。

This paper expounds the status of growth,yield and quality of Chinese Actinidia planted in the soil loss area of weathered granite and details with the amelioration of soil in experimental site. This paper also conducts systematic analysis on total input-and-output and input-and-output of economic crop interplantcd in the experimental site. The results indicate that the average annual input and output of the experimental site are 553 and 903 yuan per mu respectively and the ratio of output to input is 169. 3% for 5 years. In the fifth year,a net profit of more than 1800 yuan per mu is gained. It is proved that introducing Chinese Actinidia in the soil loss area of weathered granite is feasible and has obvious effect.
