First, planting sites and soil requirements

Bi Xi hi dry and sunny environment, so when planting to choose a high ground without shade, not suitable for planting in the ditch and the edge of the pond, should not be planted next to the tree with a large crown, so as not to affect its ventilation. Peach enjoys fertile and sandy soils with good permeability and neutral or slightly alkaline. When planted on viscous heavy soil or heavy salt alkali land, not only the plants cannot flower, but also the tree vigor is not prosperous and the pests and diseases are serious.

Second, water and fertilizer management

Peach is drought-tolerant, and is afraid of dampness. Generally, it is not necessary to water the other seasons, except that in early spring and late autumn, each time it is poured and frozen water is frozen. However, in hot weather in summer, in case of continuous drought, proper watering is very necessary. In the rainy days, drainage work should also be done to make the plants dead due to the waterproof roots.

Bi peach fertilizer, but not too much, can be used fermented fermented cattle manure as a base fertilizer, apply some sesame sauce residue before winter every year, 6 to 7 months with 1 to 2 times available phosphorus, potassium, can promote flower bud differentiation.

Third, trim

Bitters are generally trimmed after flowering. In combination with plastic surgery, the branches and branches of the disease, the drooping branches, the inner litchi, the dead branches, the thin and weak branches, and the absurd branches are cut off, and the branches that have been flowered are also cut short, leaving only two or three buds at the base. When these branches reach 30 centimeters in length, they should be picked up in time to promote full axillary buds for flower bud differentiation.

IV. Pest Control

The diseases and insect pests of Bichon often occur in the summer and autumn. The main diseases are: perforation, anthrax, fluid gum disease, and leaf atrophy. If it happens, it can be sprayed with 70% thiophanate-methyl 1000 times solution, and it can also be used interchangeably with chlorothalonil. The main insect pests are grasshoppers, red spiders, scale insects, and red neck beetles. If they do occur, 40% omethoate milk can be used to spray 1000 times to kill aphids, red spiders, and scale insects. Adults of red neck beetles can be artificial. After killing, larvae can be injected into the wormhole with pesticides such as dichlorvos, and the hole is sealed with mud. Applying white to trunks and stout branches in winter has a good effect on preventing and controlling larvae breeding in longhorn beetles.
