池杉具有生长快、病虫害少、耐水湿、干形直、材质好、萌芽力强等特点。在湖滨水网地区栽植,很受群众欢迎。为了加速繁殖,以满足大面积造林的需要,在毛主席无产阶级革命路线指引下,近年来我所开展了四季扦插繁殖试验,使池杉苗由1974年的1.9万株,到1976年猛增到240万株。其具体做法是: 一、春季硬枝扦插与劈蔸栽植1.硬枝扦插:选肥沃疏松排灌方便的土地作圃地,及时整地,每亩施塘泥6,000-8,000
Ipomoea with rapid growth, fewer pests and diseases, water wet, dry straight, good material, strong germination characteristics. Planting in the lake water network area, very popular with the masses. In order to speed up breeding and meet the needs of large-scale reforestation, under the guidance of Chairman Mao’s proletarian revolutionary line in recent years, I conducted a four-season cuttage breeding experiment, making the Ipomoea from the 19,000 in 1974 to surge in 1976 To 240 million. The specific approach is: First, the spring hardwood cuttings and split 蔸 planting 1. Hardwood cuttings: Choose fertile loose irrigation and drainage convenient land for nurseries, and timely preparation of soil, mud per acre 6,000-8,000
