Watering-free tree-planting method

Abstract

The invention discloses a method for planting tree without watering, comprising breeding and replanting. The breeding comprises: making incubator, preparing culturing soil with house refuse, planting the sapling of yearly or perennial crop in incubator, watering for every 10-15 days, the breeding time is from the last ten days of March to the earliest ten days of May and lasts 2-3 months. The replanting comprises: chosing a field with dry soil layer less than 60 cm in July or August, digging a pit with a bench, dressing in deep place and place the incubator on the bench with sunny surface facing south, removing the bottom board and filling soil. The method solves problems of little water source and low survival rate in arid and half-arid northern areas for tree planting in spring, and takes house refuse as fertilizer which is environmental-friendly. The method is characterized by the high survival rate of above 90% and low cost.

Description

technical field [0001] The invention relates to a method for planting trees, in particular to a method for planting trees without watering. Background technique [0002] Now the wind and sand invasion is becoming more and more serious, and the three northern regions with severe desertification in my country are all areas with severe spring drought. Generally, the annual rainfall is less than 500mm, and this low rainfall is also concentrated in summer. Generally, the summer rainfall accounts for the whole year. About 70--80% of the total, nine droughts in ten years in spring, spring tree planting must be watered, desertified and sandy areas are inherently barren, even if the tree is watered once in spring, the survival rate is still low, and it can survive without watering There are very few of them, and the growth of the surviving ones is also very slow, which causes great difficulties for afforestation to prevent wind and fix sand. Contents of the invention [0003] The ob...
