玉林地区荔枝大小年很普遍,不仅表现在单株产量年多年少,且在大面积上产量相差一至十几倍,目前全地区平均株产只有3—5斤。这与有些成年树株产几百斤,甚至上千斤的差距很大。大小年与低产的原因是多方面的,与品种特性、气候因素、栽培措施有密切关系。根据我场多年的试验,主要抓好稳攻秋梢,巧控冬梢和促花保果三项措施,使进入结果的荔枝树能够连续五、六年丰产,12龄树可株产40—60斤,15龄树可株产100斤以上,有的株产200斤以上。现介绍如下:
Yulin litchi size is very common, not only in years of performance per plant, and in a large area on the yield difference of one to ten times, the current average yield of the entire region only 3-5 kg. This is a few kilograms of trees with some adult strains, or even a big gap between the great. The reasons for the size of the year and the low yield are many, and are closely related to variety traits, climatic factors and cultivation measures. According to my field test for many years, we mainly focus on three key measures, namely, steady attack and autumn tip, smart winter tip control and flower and fruit preservation, so that the fruiting litchi tree can yield five or six years of high yield continuously, and the 12- 60 pounds, 15-year-old tree strains can produce more than 100 pounds, and some strains of more than 200 pounds. Now introduced as follows:
