Embodiment 1

[0055] Embodiment 1. realizes the ecological afforestation of seaside saline-alkali land and / or coastal tidal flat saline-alkali land by original soil planting

[0056] (1) Selection of planting seedlings and land selection

[0057] 1. Selection of planting seedlings

[0058] In 2012, a comparative experiment was carried out on the growth of hybrid mulberry and white wax after planting in saline-alkali soil in the Dagang oil area of ​​Tianjin. Station, oil company park and Hong Kong lion living area and other experimental sites planted hybrid mulberry and white wax, and compared the growth in terms of plant height and stem thickness. See Table 1 for the relevant data measured by comparing the growth of hybrid mulberry and white wax.

[0059] Table 1

[0060]

[0061]

[0062] The results in Table 1 show that the hybrid mulberry tree is a fast-growing tree species, and its annual growth is very large under the condition of sufficient water and fertilizer supply.

Abstract

The invention provides a method for ecological afforestation of coastal saline-alkali areas by means of original soil cultivation. Broussonetia papyrifera trees which are multi-resistant, fast-growing, high-yield and high-quality trees for ecological economic forests are adopted, and a series measures including plant land selection, land consolidation, seedling preparation, water and fertilizer management, pest control, pruning and the like are combined reasonably to guarantee survival and growth of the broussonetia papyrifera trees, so that a broussonetia papyrifera greening system for the coastal saline-alkali areas can be established successfully. The method has the advantages that excessive engineering measures taken for soil is not needed, so that cost of landscape engineering can be greatly reduced; in addition, the method has promising application prospect in ecological afforestation of the coastal saline-alkali areas, mud flat saline-alkali areas and the like.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a method for establishing a greening system of coastal saline-alkali land and / or coastal tidal flat saline-alkali land. Background technique [0002] At present, the greening technologies in coastal saline-alkali land and / or coastal tidal flat saline-alkali land ecological greening engineering mainly include halophyte greening, original soil improvement greening and alien soil greening. [0003] Halophyte greening technology is the use of halophyte afforestation, which is an important method of biological measures to improve saline-alkali land. Halophytes are natural flora on saline soils, which can grow normally and complete their life cycle on saline soils, and are pioneer plants in saline-alkali soils. Using halophytes to green saline-alkali soil not only embodies the principle of ecological adaptability, but also saves a lot of natural and social resources...
