Landscape tree cultivation method applicable to saline-alkali soil

Abstract

The invention discloses a landscape tree cultivation method applicable to saline-alkali soil. The landscape tree cultivation method applicable to the saline-alkali soil comprises step1, soil improvement, wherein a soil conditioner is sprayed on the saline-alkali soil with 0.3 to 0.4 % salt content before the rain and nutrient soil and saline-alkali sandy soil are uniformly mixed according to the ratio of 1:3 to 4 for standby application; step 2, ditch excavation, wherein a 1 m width and 1 m depth of ditch is excavated out of the soil after the soil improvement in the step 1; step 3, ditch finishing, wherein 20 cm thickness of carpolite is embedded into the bottom of the ditch in the step 2 and a plastic film with holes covers the carpolite; step 4, landscape tree buried cultivation, wherein a landscape tree with the root with a soil ball is planted into the ditch, the soil ball is located below the horizontal position of the ditch, the soil ball is 5 to 6 times of the tree diameter of the landscape tree, and a plurality of pores penetrate the soil ball; step 5, landscape tree filling, wherein gaps around the landscape tree are filled with a mixture of the nutrient soil and the saline-alkali sandy soil which are prepared well in the step 1 to enable the landscape tree to be tight until the soil ball is covered; step 6, management and protection and step 7 forming.

Description

technical field [0001] The invention relates to a method for cultivating landscape trees, in particular to a method for planting landscape trees in medium-severe and secondary salinized soil. Background technique [0002] The main problems of medium-to-severe and secondary salinized soils are high soil salinity, poor water and fertilizer retention, overgrown weeds, and low survival rate of planted landscape trees. The primary measures for the development and utilization of such land are to suppress salinity and improve Salinity. In addition, secondary salinization of soil is also a new problem faced by irrigation areas. Unreasonable cultivation methods and irrigation have led to an increase in the area of ​​salinization year by year, which has seriously affected the output, quality and sustainable development of landscape trees. Therefore, it is necessary to cultivate landscape trees in saline-alkali land. The improvement and utilization of saline-alkali land and the preven...

AI Technical Summary

Problems solved by technology

[0014] Although the above-mentioned technical solution effectively reduces the salinity in the soil, the duration is not long, and the salt that penetrates into the deep soil will still rise through the capillary of the plant and gather on the surface, which is called the phenomenon of returning salt; secondly, the above-mentioned technology The proposed planting of landscape trees also has poor air permeability, and the probability of landscape trees being suffocated increases

[0015] In addition, in the Chinese patent document CN101480147A, a kind of water cultivation method of mangrove plants is disclosed. The technical solution disclosed in this patent document has certain limitations, and it is not suitable for saline-alkali land for cultivating landscape trees; in "Shanxi Science and Technology "2007 Issue 4, July 20, Published on pages 130-131, disclosed the "Analysis of Ancient Tree Transplantation Techniques", and specifically disclosed the artificial planting techniques for transplanted ancient trees. The defect is that it is not suitable for Saline-alkali land is used to cultivate landscape trees

[0016] Judging from the current research, there is no ideal technical solution for cultivating landscape trees in saline-alkali land and achieving good results.
