春季,在果树的树盘(树根下周围的树坑)上覆盖一层塑料地膜,可以改善果树的生长状况,进而促进果实品质和产量的提高.这是生产实践经验的总结.分析共原因是:一、保持了土壤水分,改善了土壤结构.覆膜后,减少了树盘下水分的蒸发,保持了土壤湿度,同时可减少灌水次数,保持了土壤的团粒结构和良好的通透性,也节省了灌水的用费和用工.
In spring, a plastic film covering the fruit trees’ tree beds (treehouses around the roots) can improve the growth of fruit trees and thus improve the fruit quality and yield, which is a summary of production practices. Is: First, to maintain the soil moisture, improve the soil structure. After coating, reducing the evaporation of water under the tree plate to maintain soil moisture, while reducing the number of irrigation, to maintain the soil aggregate structure and good permeability , But also save irrigation costs and labor.
