GPIT生物制剂在苹果树上的应用

Application of GPIT Biological Agent in the Apple Tree

GPIT生物制剂能够大幅度提高作物的光合效率和抗逆能力,使其生长旺盛,从而达到高产、优质的目的。采用不同浓度GPIT生物制剂对红富士和丹霞苹果进行了浇根和叶面喷施试验。结果表明,不同浓度GPIT处理的红富士和丹霞苹果在特性、品质、产量因子和产量上都表现出明显的效果,高浓度处理比低浓度处理效果更好;品种之间的效果差异不大,只是在效果的表达形式上有所不同。

GPIT biological agent can significantly improve crop photosynthetic efficiency and resistance ability, promote crops＇ exuberant growth, so as to achieve the high yield and high quality. Root pouring and foliar treatment experiment was conducted on the Red Fuji and the Danxia apple trees using the high concentration and low concentration GPIT biological agent separately and the experiment result showed that the treated Red Fuji apple tree and Danxia apple tree both showed obvious effect on character, quality, yield factor and yield, and the effect with high concentration was much better than the ones with low concentration. The effect difference was not so big between the two varieties, but only the expression form of the effect is different.
