The pruning of forsythia suspensa can be divided into three stages: first, the young stage, second, the middle stage and third, the old stage.
Pruning forsythia suspensa in the young tree stage is mainly to accompany the stem to promote the measurement and control of poplar, so that the crown is full.
Forsythia suspensa, as a greening and beautifying seedling, is planted in pieces on the side of roadside flower beds, usually in a natural growth and molding state. After the plants survive, let them grow freely, just after the leaves fall in autumn, or cut the top or side to make the plants orderly. If you plant a plant, the shape needs pruning. At the seedling stage, the trunk is potted first, and the buds of the branches at the base and lower part of the trunk are cut off. After the trunk grows to the ideal height, the top is cut off to promote the germination of lateral branches. After the lateral branches grow out, they need to be trimmed twice and three times to form a complete crown. In order to control Populus euphratica, it is necessary to cut off the weak branches in the crown to facilitate the growth of lateral branches and expand the crown.
Pruning forsythia suspensa in the middle age, that is, the vigorous growth period, is mainly to remove the weak and retain the strong, to cut the disease and preserve the shape, to remove the dense and bud, to remove the dense and sparse, and to cap and promote the flower. Pruning forsythia can be divided into autumn and spring. After the first frost, the plants go into a dormant state. In this period, the weak branches of plants can be cut off, and the branches and leaves that grow too densely need thinning and pruning. Not suitable for pruning robust flower branches. Forsythia suspensa flowers and buds mature that year and bloom in spring. Too much pruning in autumn and winter will affect the number of flowers in spring. After the flowering period of forsythia suspensa, a large number of new branches will germinate. Dense branches and buds sprouting in spring can be properly removed to facilitate illumination. Keep the branches, you can cut a little in spring and summer and put them on the top. One is to promote the growth of flowering branches, and the other is to control the compactness of trees and let plants expand and contract freely.
Pruning of aged forsythia suspensa. After years of growth, the growth trend of forsythia suspensa is gradually weakening, and it needs to be retracted and upgraded. Simply delete the propagation, cut off and cultivate new ones.
Retraction pruning is one of the pruning methods of flowers and trees. Simply put, it is to trim the short branches of perennial branches to transform or rejuvenate the branches and improve the light. The main purpose of pruning is to simplify complexity. Zheng Banqiao has two famous poems: Simplifying the Sanqiu Tree by Deleting Complexity, and Blooming New February Flowers. At present, most people's understanding is that writing articles should delete tedious and redundant words, be concise, have novel ideas, don't accept other people's wisdom, and echo other people's views. After reading it, people feel like bloom in February, bringing forth the old and bringing forth the new. In fact, this poem by the poet is a high summary and guidance of the classic retraction and pruning techniques of flower cultivation. The poem accurately explains the time of pruning: autumn, the principle of pruning: delete the complex and simplify it, that is, remove the dense and leave the sparse, and the effect of pruning is:, that is, the shape is strange, the ornamental value is: February flowers, with different meanings. Thus, the poet can not only draw bamboo, but also master the way of cultivating flowers and pruning. It just uses gardening pruning to express its new literary creation concept. Writing is a bit off topic. For the trunk that has withered all the year round, carry out shortcut treatment and cultivate new trunk. At the same time, it is necessary to prune the old roots to promote the germination of new roots and restore their vitality.
