Culture method of moderate saline-alkali soil straight-stem Chinese tallow seedling

Abstract

The invention discloses a culture method of a moderate saline-alkali soil straight-stem Chinese tallow seedling. The method includes the steps of soil processing, seedling bed arranging, sowing and seedling period managing. The width of the bed surface of a seedling bed is set to be 1.5 m. In order to relieve the influences on drainage ditches when slope collapse easily happens to saline-alkali soil, during bed preparing, the in-bed small drainage ditches are set to have the upper opening width of 50 cm, the lower opening width of 40 cm and the depth of 40 cm. In order to overcome the growth characteristic that Chinese tallow two-fork branches are prone to forming a bent trunk, three times of trimming operation is conducted in the last ten days of July, the middle ten days of August and the middle and last ten days of November. In order to overcome the spike top phenomenon of Chinese tallow in winter, one robust bud at the upper most portion of the trunk is kept in spring every year, and new buds within the range 10 cm above and below the kept bud on the trunk are removed. By means of the culture method, the Chinese tallow seedlings suitable for engineering afforestation can be cultured on the basis of sufficiently utilizing Jiangsu coastal area moderate saline-alkali soil resources, and the culture cost and labor intensity can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of woody plant cultivation, and relates to a method for cultivating straight Chinese tallow tree seedlings in moderate saline-alkali soil. Background technique [0002] Chinese tallow tree is a deciduous tree with a tidy crown and beautiful leaf shape. The autumn leaves are in full swing when frosted, and they are very beautiful. If it matches with pavilions, flower walls, rocks, etc., it is also very harmonious. In winter, the white Chinese tallow tree hangs all over the branches and will not wither for a long time. The Chinese tallow tree can be planted alone or clustered on lawns, lakesides, and pools. It can be planted as embankment trees, shade trees and street trees in landscaping. In urban gardens, Chinese tallow tree can be used as a street tree, and can be planted in road landscape belts, squares, parks, courtyards, or in scenic spots and forest parks in patches, which can produce good landscaping effects. ...

AI Technical Summary

Problems solved by technology

But it is aimed at the Chinese tallow tree seedlings that have been cultivated in normal soil, and there is no expression for the Chinese tallow tree seedlings that are directly sown in moderate saline-alkali land, so it cannot be used for the cultivation of straight bar seedlings after direct seeding of Chinese tallow tree in moderate saline-alkali land Provide technical inspiration
