近年来,我国各地普遍发展山楂生产,特别是豫、鄂、陕接壤区发展较快。如何使山楂幼树早结果、早丰产,这是广大新发展区果农最为关心的问题。本文仅就山楂幼树增枝促花的夏剪措施做一简介,供参考。一、山楂幼树增枝促花的意义和基本原理山楂产量构成因素:一是结果枝数:二是平均果枝座果数;三是平均单果重量。这三个产量构成因素既适用于单株,也适用于单位面积。结果枝是由营养枝转化而来的。增加枝量并使一部分枝及时转化,既有供应树体营养物质的营养枝,又有生产果实的结果枝,则幼树扩大树冠、早结果、早丰产就有了保证。果枝座果数量与花芽、花朵质量及果实发育状况等有关,同时也与
In recent years, hawthorn production has been widely developed in various parts of China, especially in the bordering areas of Henan, Hubei and Shaanxi. How to make early results of hawthorn saplings, early bumper crop, which is most concerned about by the farmers in the new development zone. This article only on the hawthorn seedlings to promote summer cut measures to make an introduction for reference. First, the meaning of hawthorn saplings to promote the growth of flowers and the basic principles Hawthorn production factors: First, the results of the number of branches: the second is the average number of fruiting branches; third is the average weight of fruit. The three yield components apply to both plant and unit area. As a result, the branch is transformed from the vegetative branch. Increase the amount of branches and make part of the timely conversion of branches, both the supply of vegetative nutrients tree branches, as well as the production of fruit branches, the sapling to expand the crown, early results, early yield has been guaranteed. The number of fruiting branches and flower buds, flower quality and fruit development status, but also with
