近年来,化学调控在果树生产中的作用日益重要,但若使用不当,易影响果树生长发育,因此,必须注意以下问题。 1.注意加强土肥水管理 植物生长调节剂不能代替光、温、水、肥等果树生长发育的基本条件,只有在加强肥水管理的基础上,才能达到事半功倍的效果。 2.注意浓度 植物生长调节剂一般在极低的浓度
In recent years, chemical regulation plays an increasingly important role in fruit tree production. However, if it is not properly used, it will affect the growth and development of fruit trees. Therefore, the following problems must be paid attention to. 1. Note that to strengthen soil and fertilizer water management plant growth regulator can not replace the basic conditions of light, temperature, water, fertilizer and other fruit tree growth and development, and only in strengthening the management of fertilizer and water to achieve a multiplier effect. 2. Note that concentrations of plant growth regulators are generally at very low concentrations
