枣树是朝阳市主要经济树种之一,栽培历史悠久,分布面广,在山区经济建设中占有一定地位,是山区建设不可少的树种。枣为多花植物,花芽当年分化,多次分化,随枣吊生长花原始体在枣吊叶腋间由下向上逐节形成。单花分化需要一周左右时间,整株分化期需2个月时间。大量的花芽分化与枝条、叶片生长,开花结果同步进行,导致树体内贮藏营养大量消耗,形成了“百花一果”和落花落果现象。为了解决因花量过大消耗营养,影响枣树产量的主要矛盾,我们于1985年根据激素在果树方面的应用,做了枣树花期喷布激素的试验。
Jujube is one of the major economic tree species in Chaoyang City. It has a long history of cultivation and a wide distribution. It occupies a certain position in the economic construction of mountain areas and is an indispensable tree species in mountainous areas. Jujube is more flowering plants, flower buds then differentiated, multiple differentiation, with the jujube hanging flower primitive body in the jujube leaf axillary space from the bottom to the formation of section by section. Single flower differentiation takes about a week, the whole plant differentiation period of 2 months. A large number of flower bud differentiation and shoots, leaf growth, flowering results simultaneously, resulting in a large amount of consumption of the tree body storage of nutrients, forming a “flower of a flower” and the phenomenon of falling flowers. In order to solve the main contradiction caused by excessive consumption of nutrients and affecting jujube yield, we conducted a test on sprouting hormone at jujube flowering stage in accordance with the application of hormones in fruit trees in 1985.
