摘要: 以大五星枇杷幼树为材料,以多效唑土施、叶面喷施及混合施用(土施和叶面喷施结合)作处理,研究了多效唑对枇杷幼树生长和结果的影响;结果表明,多效唑能抑制枇杷营养生长,促进花芽分化,提高产量。但不同处理方法和浓度的作用存在差异,在一定范围内,浓度越高对营养生长的抑制越明显,成花率越高,早期产量越高。综合控梢、促花和提高产量等效应,以土施0.6g/m2(有效含量)结合叶面喷施1000mg/L两次为最适处理方法。

Abstract: The growth and fruiting characteristics of Dawuxing loquat were studied in the experiment by fertilizing PP333 into soil, spraying it over the leaves and fertilizing the combination of them. The results show that PP333 can control the vegetative growth, promote the differentiation of flower buds and increase the yield for the loquat trees. There are some differences among the different treatments and concentrations. In certain limits the higher concentration of PP333 makes the higher rate of flower buds and the better yield. The best effective treatment is the fertilizing PP333 of 0.6 g/m2 two times by spraying 1000 mg/L over the leaves for controlling shoots, promoting initiation of flower buds and increasing yield.

Key words: loquat, PP333, growth, fruiting
