① Retract the main branches, promote the germination of new branches and renew the tree body.
(2) Using the long branches and upright branches in the inner chamber, a large fruiting branch group is cultivated to enrich the inner chamber.
(3) grafting bare parts to fill the gaps and make the trees plump.
(4) renewing the branches, removing the weak and retaining the strong, removing the flat and keeping the straight, and shortening the strong branches in the large and medium-sized branches to delay the aging of the branches.
Reasons for the weakness of peach trees
One: only water, not fertilize.
Because the output of young trees is not much, many peach farmers have the idea of "not spreading eagles without seeing rabbits" Some peach farmers do not apply fertilizer at all, or only apply a small amount of urea, which leads to the abnormal growth of individual peach roots.
Two: Too much rain.
In the first half of this year, there were heavy rains in May and June, especially in July. The soaking time of individual peach trees is too long, which reduces the soil permeability, suffocates the capillary roots due to hypoxia, and weakens the trees.
Three: root dysplasia
In July last year, seven or eight peach trees in Taoyuan, a peach farmer, had this symptom on the roadside of Zhang Jianfeng Village in Linyi Town. He asked me if it was root rot, and I said no, mainly because of poor investment and poor root development. He didn't believe it and insisted on digging a tree to see what was going on. Results The root system was intact and there was no root rot, but the capillary root was underdeveloped. After increasing investment this year, all the above symptoms disappeared.
