The results showed that application of microbial fertilizer could increase the yield, fruit weight and fruit shape index, significantly increase the flowering rates and inflorescence fruit setting rate of following year, while reduce the fruit hardness and soluble solids content, and the effect of microbial fertilizer and compound fertilizer mixed application on increasing fruit weight and yield was higher than that of microbial fertilizer separate application, the effect of the two was not obvious in other aspects. Therefore, microbial fertilizer could be used instead of some chemical fertilizer and organic fertilizer in apple production to reach the aim of increasing yield and efficiency, and the effect of microbial fertilizer and compound fertilizer mixed application was best.展开更多

The result indicated that: cross-pollination had a significant impact on both fruiting rate and seed-setting rate;cross-pollination improved the nut number in each burr of each variety, in which “Duanci” was the biggest beneficiary, whose number of nut per burr increased from 1.08 to 2.77, 156% higher than that of the self-pollination combination;nut weight showed no significant difference in Xenia Effection;“Zunyu” improved the yield of “Yanhong” most;“Donglingmingzhu” was regarded as the best tree to improve “Zunyu”’s yield;the best variety to improve yield of “Zipo” was “Zunyu”;“Donglingmingzhu” and “Duanci” improved yield of each other most.展开更多
