龙溪地区气候适合柑桔栽培,柑苗定植后加强管理一年多次抽梢,树冠形成快,是获得早产的有利条件。但要达到早产稳产,必须调节枝梢的抽发和生长。目前生产上由于施肥不当,枝梢生长紊乱,病虫发生猖獗,导致树势衰弱,造成大小年结果和早衰现象。 1975年春和1978年夏我们分别在红壤水田和丘陵地重新栽植芦柑各一片,共计16亩,作为试验园,围绕如何控制柑桔枝梢生长来达到丰产稳产这一关键问题进行试验。其中水田片经1977和1978两年试产后,1979年开始正式投产,3年平均亩产达4～6千斤。从目前树势情况看来,稳产还很有潜力。现就几年来对芦柑枝梢生长与早产稳产之间的关系作初步探讨如下: Longxi climate suitable for citrus cultivation, citrus seedlings strengthen management more than a year after planting tips, the formation of fast crown, is to obtain favorable conditions for preterm birth. However, to achieve stable preterm birth, it is necessary to regulate the aspiration and growth of shoots. At present, due to improper fertilization in production, branches and shoots grow disorderly, pests and diseases occur rampant, resulting in frail weakness, resulting in the size of the year results and premature aging phenomenon. In the spring of 1975 and the summer of 1978, we re-planted one piece of citrus in paddy field and hilly land of red soil respectively, totaling 16 mu. As a test garden, we tested the key issue of how to control citrus shoot growth to achieve high yield and stable yield. Among them, paddy fields were put into trial operation in 1977 and 1978 respectively, and their production started in 1979. The average yield per mu in 3 years reached 4 to 6 kilos. It seems from the current situation of the tree, stable production still has great potential. Now on the few years of root growth and the stability of premature delivery of citrus for a preliminary relationship between the following:
