造林初期林地裸露,在幼林内间种农作物,使之形成既有利于幼林生长,又能增加短期收益的复合栽培群落。武穴市石佛寺镇,1990年栽杉树180亩,套种西瓜30亩,产量4.6万公斤,价值1.82万元。套种花生150亩,产量0.88万公斤,价值1.75万元。1991年栽杉树500亩,套种西瓜90亩、花生200亩,收入5.55万元。同时,新造林成活率达97％,树木年增高1.2米,比没有套种的林地造林成活率提高12％,树木生长增高15％。
In the early stage of afforestation, the bare land is planted and the crops are planted in the young forest so as to form a composite cultivation community that is beneficial to the growth of young trees and to short-term benefits. Shifushi Temple in Wuxue City, 180 acres of planted trees in 1990, 30 acres planted watermelons, output 46,000 kilograms, the value of 18,200 yuan. Intercropping 150 acres of peanuts, yield 08,800 kilograms, the value of 17,500 yuan. 1991 planted 500 acres of cedar, intercropping watermelon 90 acres, 200 acres of peanuts, income 55,500 yuan. At the same time, the survival rate of new afforestation reached 97%, and the annual increase of trees was 1.2 meters. The afforestation survival rate increased by 12% and the growth of trees by 15% than that without afforestation.
