【摘要】 杨梅幼苗定植采用全脱叶,培士至穗顶,复盖地膜,挖大种植穴等措施,成活率可达98％,定植后1～3年内采用每年冬扩穴,配方追肥,施肥量逐年倍增,结合拉技整形修剪等措施,使前期促进幼树生长迅速形成具有结果能力的树冠。然后从第4年起,减少氮肥,增加钾肥,根施多效唑等及时控制营养生长,促进生殖生长,使幼苗定植后第4年平均株产12.38公斤,第5年平均株产29.58公斤。更多还原

【Abstract】 The survival rate of bayberry reached 98% after taking the measures of cutting off leaves, banking up to the stiouic top, mulching, digging big hole etc to the plantlet transplanted.In order to promote growth and form fruiting crown rapidly, within 3 years after planting, the comprehensive measures of enlarging the planting hole in winter each year,manuring rationally,drawing the branches,shaping and pruning were adopted.From the fourth year,the norm of nitrogen fertilizer was reduced and potassium fertilizer increased,and paclobutragol was applied to the root place.Then the vegetative growth was controled and the repoductive growth was promoted.In the fourth year the -average yield reached 12.38 Kg per tree.In the fifth year reached 29.5 Kg per tree.更多还原
