为了改善平原农田生态环境,保障农业丰收,开辟木材生产新途径,近年来,宜春地区把发展平原农田林网建设提上了议事日程,全区已有10万亩农田初具林网雏型。1983年冬,丰城市杜市乡口前村徐桥村民小组,在260亩农田田埂上,每隔2米栽上一株池杉树,平均每亩农田有树20—25株。到去年年底测定,平均树高达到5.19米,平均胸径8.72厘米,从植树后的第三年开始,平均每亩每年增长木材0.2—0.25立方米,相当于农田纯收入的50%。如今,人们来到徐桥村,便有一种被“林海”包围的感觉,展现在眼前的是一幅“田中栽树,林中种田”的新景象。田埂植树会不会影响农作物生长?近两 In order to improve the ecological environment of the plain farmland, ensure the bumper harvest of agriculture and open up new ways of wood production, in recent years, Yichun Prefecture put the development of farmland and forestry net in the plain on the agenda. In the winter of 1983, a group of Xuqiao villagers in Ducunxiangkou Village, Fengcheng City, planted a pool of Ipomoea ciconia at intervals of 2 meters on 260 mu of farmland. On average, there were 20-25 trees per acre of farmland. By the end of last year, the average tree height reached 5.19 meters with an average diameter of 8.72 centimeters. From the third year after tree planting, the average annual increase of 0.2-0.25 cubic meters of timber per mu is equivalent to 50% of the farmland net income. Nowadays, when people come to Xuqiao Village, there is a feeling of being surrounded by “Linhai ”, which shows in front of us a new scene of “planting trees in the fields and farming in forests”. Tian 埂 planting trees will not affect crop growth? Nearly two
