1. Look at the transformation of trees mainly to do the following four points: First, conduct reasonable thinning for those orchards that have been planted densely to facilitate ventilation and light transmission, and prevent the outward movement of hanging fruit; second, gradually improve old and weak diseased plants with low utilization rate. Replace, promptly transplant with soil to make up for the large trees that have been fruited, ensure the number of basic plants, and thirdly, apply the heavy-grained trees to reduce the tree vigor in the garden due to excessive fruiting, so that they can quickly recover their vitality and safely overwinter. The growing trend is even in the following year. Fourth, the whole park is divided into batches to carry out heavy fertilizer application in order to benefit the growth of the root system.
2. Look at the tree pruning is a meticulous work, which includes the management and correction of the tree line; the result is reasonable matching of the branches and vegetative branches; the removal of the weak disease branches. Pruning in winter should be done: First, the timely removal of unfamiliar late autumn pods and diseased leaves; second is to determine a good mix of good vegetative shoots and fruiting branches, the ratio of 3:2 is better; third is cut off injury , pests, weak branches, cross branches.
3, see tree fertilization in the management of the orchard, although the use of the same method, due to differences in the physiological and physiological characteristics, there will be uneven phenomenon, which requires the use of fertility in the sparse tree, weak trees The clever method, as far as possible to regulate the vegetative and reproductive growth to the same level.
4. Prevention and control of pests and diseases In order to clean up the wintering sites of pests and diseases in time, work on the clearing of deciduous and fruit-falling, sprayed lime sulfur, and trunk whitening.
