EF植物生长促进剂系从桉树中提取的天然生物活性物质,它具有增强植物光合作用,促进生长和花芽分化,增加干物质积累,减轻病害,从而提高产量和改善品质。1980年以来,我国先后在葡萄、油菜、苹果、桑树等植物上应用,均有不同程度的增产。我所用EF促进剂50ppm浸西瓜种子,对提高发芽率和发芽势有明显效果。1987年用EF植物生长促进剂对碰柑的壮果效应进行了试验,取得了较好的效果。 材料和方法 试验在湘西自治州蚕桑试验站碰柑园内
EF plant growth promoter is a natural bioactive substance extracted from eucalyptus. It has the functions of enhancing plant photosynthesis, promoting growth and flower bud differentiation, increasing dry matter accumulation, alleviating diseases, thereby increasing yield and improving quality. Since 1980, China has successively applied grapes, oilseed rape, apples and mulberry plants to different degrees. I used EF accelerator 50ppm immersed watermelon seeds, to improve the germination rate and germination potential have a significant effect. In 1987, EF plant growth promoter was used to test the effect of fruiting and fruiting of Pesticide. The better effect was obtained.
