The new peach tree should be managed in this way (planted in the field): adopt a tree shape-naturally happy shape, cultivate three main branches, the included angle between the main branches is about 65438 0.20 degrees, and the opening angle of the main branches is about 45 degrees. There is no large branch group on the back of the main branch, and more back branches and side branches can be left. Peach trees planted in the field are generally not picky (not in flowerpots). The main pests and diseases on peach trees are aphids, red spiders, Laodelphax striatellus, liriomyza sativae, caterpillars and bacterial perforation. Control measures are omitted. At present, the key point is to control aphids, which can be controlled with imidacloprid or acetamiprid 2000 times solution.
