Litchi cultivation dwarf close an important measure - cutting-back

Litchi tree dwarf problem is low density constraints an important factor in the effectiveness of cultivation. To carry out cutting-back, in the control of tree size and flowering success of outcomes. 83 mu-sik (2m × 4m) of the Lai Chi Yuen in the 4th year after planting began there were obvious strains overlap shoot, take the fifth year after the mild fruit cutting-back, the sixth year after mining started in the fruit degree of cutting-back to control plant height not exceeding 2.5m, crown width of not more than 2.5m; mu-sik, 55 (3m × 4m) colonization of the Lai Chi Yuen in the first 7 years after the adoption of moderate fruit cutting-back to control tree height does not exceed 2.5m, crown width of not more than 3.0m. To carry out cutting-back after the fertilizer management in strengthening the conditions, both before the beginning of October more than 95% germination of the growth of two plants can be robust, the 2nd to be ideal, flowering the following year the rate of 86% to 100% . Mu-sik, 55 test areas, with mild retraction of the eighth year after pruning trees yield an average of 16.135kg, not cutting-back than the seventh year of production increased 431% strain; mu-sik, 83 test areas, moderate retraction After cutting the average strain of the middle of the eighth 5.924kg, slightly more than cutting-back strain after the seventh year that the average yield increase of 50%. Introduced a specific method of cutting-back.
