君迁子是我区山区的柿树砧木,种子发芽率高,幼苗生长健壮,与柿树嫁接亲合力强。当地群众习惯于君迁子苗定植后二、三年进行嫁接。 我区系干旱山区,冬春降水少,而全年降水量的70—80％集中在七、八月份的雨季。以往采取常规的冬春季裸根苗造林,成活率多在20—30％之间。为了提高在干旱山坡梯田上君迁子造林成活率,我们于1982年3月上旬开始培育君迁子容器苗,8月上旬造林979亩,33,000株,在10月上旬进行调查,成活率达97.3％。现将技术过程简报于下:
Jun Qianzi is a mountainous area in our district persimmon rootstocks, seed germination rate is high, robust seedling growth, affinity with persimmon graft affinity. Local people are accustomed to Jun Qian seedlings planted two or three years after grafting. I am a district of arid mountainous area with less precipitation in winter and spring, while 70-80% of the annual precipitation is concentrated in the rainy seasons in July and August. In the past to take the conventional spring and winter bare root seedlings afforestation, the survival rate of more than 20-30%. In order to improve the survival rate of Junlingensis on arid hillside terraces, we started cultivating Junlinzi container seedlings in early Mar. 1982 and 979 mu and 33,000 afforestation in early Aug. The survey was conducted in early October with a survival rate of 97.3 %. Now the technical process briefings below:
