How to dwarf litchi trees

Litchi is a very delicious fruit, distributed in the southwest, south and southeast of China, and is mostly cultivated in Guangdong and southern Fujian. So, some litchi trees grow too vigorously, resulting in too many trunks affecting the yield, the following editor will introduce how litchi trees are dwarfed.

1. Open a large hole and apply sufficient base fertilizer before planting

In order to create suitable soil conditions for rapid root growth and rapid growth of litchi young trees, so as to enhance plant resistance and achieve dwarfing, early fruiting and high yield of litchi. Before planting, the deep hole, 0.8m × 1m × 1m long, was applied with sufficient base fertilizer, garbage fertilizer 40~50kg, peanut bran, calcium superphosphate and lime each 0.5kg.

2. Select high-quality seedlings and increase unit yield by reasonable close planting.

Reasonable close planting and dwarfing cultivation has long been an important technical reform in modern fruit tree production, which is conducive to changing extensive cultivation into fine management and achieving the goal of early fruiting, high yield and high benefit. And achieve the effect of high yield and stable yield. In order to make full and rational use of land and light energy, increase the early yield, and achieve high yield and high efficiency. We adopted the plant row spacing of 4m × 5m, planting 35 plants per 667m2, changing the traditional cultivation habit of 20 plants per 667m2. The grafted seedlings of Feizixiao and Guiwei, which are suitable for local fast-growing, high-quality and early fruiting, were selected as seedlings and planted in April 2011. When planting, cut off the main root, retain the main root 12~15cm, cut off the vertical root properly, and retain the horizontal root system. The aim is to promote the formation of the root system of early-bearing and high-yield trees with shallow and small main roots, many and shallow whisker roots and wide root distribution. After planting, arrange the planting hole into a tree plate, and keep the tree plate covered.

Litchi dwarfing and high-yield cultivation techniques are mainly to adjust the planting density and properly prune seedlings. In addition, it is also important to select good varieties.
