本研究主要针对我省不同地区的不同土壤条件下适宜苹果树生长发育的氮磷钾配合比例的专用复肥及其施用技术,为计划生产和科学使用,提供依据.本试验属于“矫正”施肥的范畴,根据我国目前化肥生产水准及单质肥料有效成份较低的实际情况而设计的复肥型号,尚不能达到苹果树生长发育所需要的较理想的配比,达不到“补偿”施肥的目的.但就目前生产水平和实际情况,所筛选的型号,还是比较好的.
This study mainly aimed at the special compound fertilizer and its application technology suitable for the proportion of NPK in different soil conditions in different regions of our province and provided the basis for the planned production and scientific use.This experiment belongs to the field of “ According to China’s current level of fertilizer production and simple elements of the actual situation of low fertilizer and the actual design of the compound model, still can not achieve the apple tree growth and development required more than the ideal ratio, less than ”compensatory" fertilization However, the current level of production and the actual situation, the selected model, or better.
