Shaping and pruning method for increasing yield of Mili pear and cultivation method

Abstract

The invention discloses a cultivation method for increasing the yield of Mili pear, which relates to the technical field of fruit tree cultivation. The method in the technical scheme comprises the following steps of S1, varieties and seedlings, S2, planting, S3, soil management, S4, fertilizer and water management, S5, trellis construction, S6, shaping and pruning, S7, flower and fruit managementand S8, disease and insect pest control. The cultivation method has the beneficial effects that on the basis of the open center shape, good light distribution density is ensured under the tree shape;due to the uncertainty of the tree shape growth, a reform is made on the basis, heavy cutting back is done frequently, the growth of each growth branch is balanced, the light is more uniformly distributed, and the yield of parts in a sub-inner layer and an inner layer is increased. The light distribution in a canopy not only affects the yield, but also has a more prominent effect on the quality offruit. While the yield is increased, the proportion of high quality fruits in the parts in the inner layer and the sub-inner layer increases significantly because of the enhanced light intensity in the inner layer and the sub-inner layer.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a shaping and pruning method and a cultivation method for improving the yield of honey pears. Background technique [0002] Plastic pruning is to form a reasonable tree structure, effectively use space and light energy, adjust the nutrient distribution of the tree, make the pear tree fruit early, produce more fruit, and bear good fruit, and prolong its life. [0003] The main tree shapes commonly used in southern pear areas are evacuated layered shape and multi-main branch happy shape. The evacuated layered shape is similar to the natural growth state of pears, with good ventilation and light transmission. Compact structure, strong wind resistance. [0004] The light distribution of different tree shapes and different parts has an impact on the yield and quality of honey pears. There are significant differences in the relative light intensity between different tre...

AI Technical Summary

Problems solved by technology

[0005] At present, the commonly used evacuated layered shape and the multi-main branch happy shape, the diurnal variation of the light intensity of the two canopy layers is gradually decreasing from the outside to the inside, and the light in the outer layer is obviously better than that in the inner layer, resulting in different degrees of fruit quality. difference
