Method for improving fruit tree seedling planting survival rate at Hexi Corridor areas

Abstract

The invention relates to the field of tree planting, and specifically relates to a method for improving fruit tree seedling planting survival rate at Hexi Corridor areas. According to the invention, livestock manure, furfural residue, straws and weeds are filled into high-yield ditches or field planting pits, wherein the weeds or straws are placed at the bottom of the high-yield ditches or field planting pits, and the livestock manure and furfural residue are well mixed and placed on the weeds or straws. Therefore, fertilizer application efficiency is fully improved, and a fertility duration is long. During a backfill process, surface mellow soil is first filled into the high-yield ditches or field planting pits, and bottom immature soil is backfilled; winter water is irrigated for composting and wintering, such that soil overall fertility is effectively adjusted. A phosphate fertilizer slurry is prepared, wherein the phosphate fertilizer is calcium phosphate or diammonium phosphate. The phosphate fertilizer is prepared into a phosphate fertilizer mixed liquid with water according to a weight ratio of 1:4; soil is added into the phosphate fertilizer mixed liquid, and the mixture is stirred into the slurry. Roots without wound white mulches are dipped with the phosphate fertilizer slurry, such that phosphate fertilizer application and absorption effects are better. Also, phosphate fertilizer dose is reduced, such that pollution is reduced.

Description

technical field

[0001] The invention belongs to the field of tree planting, in particular to a method for improving the survival rate of fruit tree seedling planting in the Hexi Corridor area. In particular, a method for planting fruit trees on sandy loam soil and sand leaking ground in the Hexi Corridor area. Background technique

[0002] The Hexi Corridor area is rich in land types, including loam, sandy loam, and sand leaking land, etc. Gobi and deserts are widely distributed, with dry climate, large transpiration, drastic changes in cold and heat, strong wind and sand, and low precipitation, which can easily cause dehydration of fruit trees and seedlings Draw strips, the survival rate is low. In the existing planting technology, the proportion of water and fertilizer, substrate formula, planting method and other technical contents are widely disclosed. However, in actual use, it is found that the existing planting technology cannot adapt to the environment of Gobi and d...
