Plum tree winter management method:
Topdressing and land preparation: Before the dormancy of Lishu, it is necessary to apply sufficient base fertilizer, mainly organic fertilizer, combined with phosphorus and potassium fertilizer to promote the accumulation of nutrients in the fruit trees and promote the safe wintering of the plants. Fertilization can be carried out simultaneously with deep-turning and finishing, and the wintering pests in the soil will be frozen out of the surface, effectively reducing the pests and diseases in the coming year.
Disinfection, anti-freezing: thoroughly remove the residual branches, fallen leaves, fruit drop, weeds, etc., and scrape off the old bumps and scabs on the trunk of plums, and bring out the deep burial treatment in the field. The tree general disinfected and frost-proof, hindering the overwintering virus from landing on the tree, and the implants were not dry.
Plastic pruning: According to the growth situation of Lishu, appropriate amount of plastic pruning, using short cut, thinning, retracting and other measures to eliminate thin branches, diseased branches, long branches, overlapping branches, etc., to reduce nutrient useless consumption, promote germination New branches prevent the result from moving out. After trimming, the wound is applied with a callus anti-corrosion film in time to protect the wound from healing and isolate the infection.
The underground pipeline integrated pipe gallery is commonly called the common trench. It refers to the installation of pipelines that can accommodate more than two types of public facilities including electricity, telecommunications, power supply, gas, traffic signals, and closed-circuit televisions. It has complete drainage, lighting, and communications. It is to avoid repeated excavation of roads. Reduce urban visual pollution, protect the urban environment, improve urban energy supply, and ensure the new municipal infrastructure generated by the safe operation of the city.
