在伟大领袖毛主席关于“绿化祖国”和“实行大地园林化”的伟大号召指引下,近几年来,我们大搞了水杉扦插。1973年我们夏插15,000株,成活10,500株,成活率达到70％以上,当年一般生长量达到10厘米左右,最高生长量达到25厘米,苗木生长健壮。具体做法如下:一、圃地的选择和整理圃地选在靠河边便于排灌的沙壤地,在冬季进行深翻,插前20天施上基肥,每亩60担猪肥,然后进行第二次翻耕,作床前一星期每亩撒可湿性“六六六”粉5斤,以杀死地下害虫,再将圃地耕细耗平作床。苗床为东西向,床面宽4尺,墒沟宽1.5尺,沟深6尺,同时搭好荫棚架,架高3尺,以便于操作管理。
Under the great call of Chairman Mao, the great leader on “greening the motherland,” and implementing “the practice of the earth garden,” we have promoted the cutting of Metasequoia glyptostroboides in recent years. In 1973, we planted 15,000 plants in summer and survived 10,500 plants with a survival rate of over 70%. In that year, the average growth rate was about 10 centimeters and the maximum growth rate reached 25 centimeters. The nursery stock grew robustly. The specific practices are as follows: First, the selection and consolidation of land Choose the land for irrigation and drainage in the sand by the river for deep plowing in the winter, 20 days before the insertion of basal fertilizer, 60 pigs per mu of pig fat, and then The second tillage, as a bed for a week before the spread of wettable per acre “six six six” powder 5 pounds, to kill underground pests, and then nursery fine consumption as a bed. Seedbed for the east-west, 4-foot wide bed, furrow width of 1.5 feet, ditch depth of 6 feet, while the shade shelves, 3 feet high, in order to facilitate the operation and management.
