B9(Alar)系一种植物生长抑制剂,在苹果、梨、葡葡等果树上已广泛应用,对于抑制枝条生长,使幼树矮化,调节养分,促进花芽形成,达到早期丰产,在理论与实践上具有一定价值。我们于1975——1977年用B9对苹果金冠和茄南幼树小面积进行处理,试图从生理方面进行初步探讨。
B9 (Alar) is a plant growth inhibitor, which has been widely used in fruit trees such as apple, pear, grape and grape. It inhibits shoot growth, dwarf saplings, regulates nutrients and promotes the formation of flower buds. Early in the theory And in practice has a certain value. We used the B9 from 1975 to 1977 to deal with the small area of Apple Golden Delicious and Solanum Sawthorns, trying to make a preliminary study from the physiological aspects.
