植物生长调节剂立效是一种植物生长延缓剂,具有矮化植株、控制生长、防止倒伏、增加分蘖、使根系发达、促进开花结实等作用。为有效控制树体生长量,促进开花结实和单位面积产量,我站使用植物生长调节剂立效,采用不同浓度对密植杏园实施了叶面喷施试验研究,现将试验情况总结如下:一、材料与方法1.供试材料试验区设在轮台县哈尔巴克乡卡西比西克村2小队的0.3公顷杏园中,供试品种为轮台白杏,树龄6年,株行距2米×4米,树势强壮,土壤质地为灌漠土,肥力中等,土层深厚,园内间作冬小麦,果园管理为常规管理,采用浇灌形式。
Plant growth regulator effect is a plant growth retardants, with dwarf plants, control growth, to prevent lodging, increase tillering, so that the root system developed to promote flowering and fructification and so on. In order to effectively control the growth of tree body, and to promote flowering and fruiting and yield per unit area, we use plant growth regulator effect, the use of different concentrations of dense planting apricot orchard carried out the foliar spray test study, the test is summarized as follows: MATERIALS AND METHODS 1. Test material The test area was set in 0.3 hectare apricot orchard of Team 2 of Xixibisixi Village in Harbin, Rutai County. 2 meters × 4 meters, strong tree vigor, soil texture for the irrigation desert soil, medium fertility, deep soil, inter-garden winter wheat, orchard management for the conventional management, the use of irrigation forms.
