果树保护地栽培一般采用高密（4500－10000株ibm）栽植，加之保护栽培条件下生长空间受到限制，且高温、高湿、弱光照，易导致虚旺徒长，影响花芽分化，因此要保证早期产量，又无碍于后期管理，对整形修剪和控势挂冠有特殊要求。为此，从lop年开始连续3年对任光油机保护地栽培 Cultivation of fruit trees in protected areas generally use high density (4500-10000 ibm) planting, combined with the growth of protected cultivation conditions are limited, and high temperature, high humidity, weak light, easily lead to virtual wallet, affecting flower bud differentiation, so to ensure that the early yield , But also without prejudice to the latter part of the management of plastic trim and control have special requirements. To this end, from lop years for three consecutive years of Renguin machine protection cultivation
