Due to the physiological characteristics or improper management of the pear tree variety, the main branches of the pear tree (dry) are light-legged, and the inner and outer layers are densely formed, the result branches are weakly moved outward, the nutrients are inefficiently consumed, the fruit is small, the quality is poor, and the yield is low. In order to solve this problem, after several years of practical exploration, the author has effectively solved this problem by using the methods of bud grafting and hard branching in the three seasons of spring, summer and autumn, and it is simple and easy.
The specific operation method is:
1. In the spring, the pear trees are spliced ​​on both sides of the light leg branches (on the upper side) at a distance of 20 cm on each side to connect one (the same variety or other variety) scion. The scion cuts 2 to 3 buds, preferably leaf buds and leaf buds. The buds of leaf buds and leaf buds are not suitable for growth, and they are easy to form the resulting branch group. The good leaf buds can be grafted in the same year. The grafting method adopts a hole-punching or a branch-cutting abdomen.
2. In the summer of July, in the place where the bare legs are dry and the branches need the result branches, the buds or subcutaneous joints are used to make up the joints. In the spring of the next spring, the buds that have survived are smeared with the hairs or buds above the buds to promote their germination.
3. The autumn is carried out from late September to early October. The grafting method is basically the same as that in spring, except that the scion is mostly used as the scion.
The choice of scion is either spring. In the summer or autumn, the branches with the buds of the buds are used as the scion. Try not to use the long branches for the scion, in case the new branches are formed again.
In addition, for the empty church tree whose result is shifted outward, the "long turn back" result branch is cultivated by the long branch of the light leg, that is, the long branch on the bare leg tree is reversed back to the empty place (space). The results are cultivated year by year. In the end, the tree balance is balanced, the fruit is balanced, the production is stable, the production is high, the fruit is light, and the quality is excellent.
