根渗灌条件下施肥对核桃产量构成因素的影响

Effects of Fertilization on Yield Component Factors of Walnut under the Conditions of Infiltrating Irrigation around Roots

【目的】研究施肥对核桃花芽分化、果实横纵径及产量的影响,探讨适宜成龄核桃的施肥量和追肥次数。【方法】在根渗灌条件下通过不同施肥量和不同追肥次数的试验,研究施肥对核桃结果、果实体积及产量的影响。【结果】增加基肥施用量有利于核桃花芽分化,增加追肥量可以提高核桃结果数量和坐果率。增加施肥量尤其是追肥量可以有效增加核桃果径、果实体积。增加施肥量可以有效提高核桃产量,尤其是加大追肥量更有利于提高核桃产量。【结论】增加施肥量和基肥施用量均有利于提高核桃花芽分化,增加施肥量和追肥量均可提高核桃结果数量、坐果率和产量。

[Objective] The article project aims to analyzes the effects that fertilizing acts on walnut flower bud,fruit vertical and horizontal and yield to and explore the fertilization amount and the times of topdressing.[Method] The field experiment with two factors and three levels was applied carried out for the study in order to research the effact of fertilzing on walnut fruition,fruit size and yield.[Result] The result of shoed that adding base fertilizer.wais beneficial to walnut flower bud,adding topdressing can could increase the number of walnut and fruit setting rate,adding the amount of fertilizer,especially adding the amount of topdressing can could effectively promote the walnut fruit diameter,and fruit volume.Adding the amount of fertilizer can could also improve the yield of walnut,especially increasing topdressing is conducive to improve the yield of walnut.[Conclusion] Increasing the amount of fertilizer and base fertilizer quantity are were beneficial to improving the walnut flower bud differentiation,and increasing the amount of fertilizer and topdressing can could increase the rate of fruit setting,the number of walnut and yield.
