1978年夏秋,我们在泰兴县城北公社林场进行水杉、池杉嫩枝全光灌水育苗试验,平均成活率73%,最高达90%,年生长量水杉平均25厘米以上,池杉20厘米以上,共培水杉、池杉苗木20余万株.采用这种方法,比嫩枝遮荫,全光喷水等方法简便,省工、省材料,是多快好省繁殖水杉、池杉的新途径.现将具体做法和体会简介如下:一、圃地选择和筑床 选地势平坦、土壤肥沃、靠近水源的砂壤土,进行深耕细整,构筑高床(高15—20厘米.宽1米),并挖好排水沟.
In summer and autumn of 1978, we conducted the trial of Metasequoia glyptostroboides and Ipomoea sinensis shoots nurturing all-optical irrigation in the forest center of north of Taixing County, with an average survival rate of 73% and a maximum of 90%. The annual growth rate of Metasequoia was more than 25 centimeters, Co-cultivation of Metasequoia fir, Ipomoea capensis more than 20 million.Using this method, than the tender shade, all-water jet and other methods is simple, labor-saving, provincial material, is faster and more provincial reproductive Metasequoia, Iii fir a new way Now the specific practices and experiences are as follows: First, the choice of land and building beds Flat topography, fertile soil, close to the water of sandy loam, deep plowing, build high bed (15-20 cm high and 1 meter wide) And dig a good drain.
