我省在柑桔生产的发展中,不少产区新栽了大量的幼树,现已陆续投产,在产量组成中占有一定比例。但随着栽植面积的扩大,在一些幼龄果园中往往由于管理差或采用违反幼树生长发育特点的栽培技术,使果树不能适龄投产,以致形成“小老树”,已成为生产上急待解决的重要问题。据了解,如江津地区有“小老树”500多万株,约占栽植数的40％。我所曾针对此问题进行过一些调查与试验研究,现就了解的情况,提出以下粗浅的看法。
In the development of citrus production in our province, a large number of newly planted saplings have been newly planted in many producing areas and have been put into operation one after another, occupying a certain proportion in the output composition. However, with the expansion of planting area, some young orchards often become poorly managed or adopt cultivation techniques that violate the growth and development characteristics of saplings, so that the fruit trees can not be put into operation at the appropriate age so that the formation of “small old trees” has become urgent Solve the important issue. It is understood that, such as Jiangjin area “little old tree” more than 500 million strains, accounting for about 40% of the planted. I have carried out some investigations and pilot studies on this issue, and I now give the following superficial views on the situation.
