Coastal mudflat cultivation method for one hundred saline-alkali intolerant tree species

A salt-alkali-tolerant and tree species technology, applied in the field of arboriculture, can solve problems such as failure to form a landscape, single salt-alkali-tolerant trees, long-term plants unable to survive, etc., and achieve the effect of changing the singleness and enriching the diversity.

Problems solved by technology

[0003] The water level under the soil of coastal tidal flats is high, the content of salt and alkali is high, and there are only a few saline-alkali-resistant trees.
At present, many technologies solve the soil salinity problem on the surface through short-term soil improvement, but do not solve the problem fundamentally, and the long-term plant growth still cannot survive, or some of them only choose relatively simple saline-alkali-tolerant tree species for planting

Embodiment 1

[0018] The method for one hundred kinds of saline-alkali-resistant tree species along the tidal flats includes the following steps:

[0019] (1) First of all, the drainage system of the terrain should be done well, and the four-stage drainage method should be adopted to form a grid-based drainage system, and the alkali should be discharged in the form of rainwater or irrigation, and the irrigation frequency should be once in the morning and evening;

[0020] (2) Soil improvement: Improve soil physical properties by planting "pioneer" plants, woody plants and herbaceous plants and adding organic fertilizers;

[0021] (3) Select salt-intolerant tree species at the same latitude, such as arbor trees, flowering shrubs with salt-tolerant ability and flowering shrubs without salt-tolerant ability, and plant relatively salt-intolerant flowering shrubs on uphill or slope top;

[0022] (4) Later maintenance: Apply organic fertilizer once in spring, apply compound fertilizer and soybea...

Abstract

The invention discloses a coastal mudflat cultivation method for one hundred saline-alkali intolerant tree species. The coastal mudflat cultivation method comprises the steps of building a geomorphic drainage system, forming a meshing drainage system by a four-step drainage method and discharging alkali through rainwater or irrigation; performing soil improvement namely planting pioneer plants, woody plants and herbaceous plants and combining with increasing applied organic fertilizer to improve physical properties of the soil; selecting saline-alkali intolerant tree species with the same latitude such as arbor trees, flower shrubs having the salt tolerance and flower shrubs free of the salt tolerance to plant and planting the relatively salt intolerant flower shrubs at uphill positions or slope tops; performing later period maintenance comprising applying once organic fertilizer in spring, applying compound fertilizer and soybean meal in autumn and watering in late autumn and winter with less rainfall according to a certain time interval to suppress salt accumulation of the soil. The coastal mudflat cultivation method for the one hundred saline-alkali intolerant tree species has the advantages of changing the oneness of coastal mudflat seedling types, enriching the diversity of the tree species, enabling various plants with the same latitude to grow and enabling the wasteland to be reconstructed into an ecological garden.

Description

[0001] technical field [0002] The invention belongs to the technical field of arboriculture, and in particular relates to a method for cultivating one hundred kinds of saline-alkali-intolerant tree species along tidal flats. Background technique [0003] The water level under the coastal tidal flat soil is high, the content of salt and alkali is high, and there are only a few saline-alkali-resistant trees. At present, many technologies solve the soil salinity problem on the surface through short-term soil improvement, but do not solve the problem fundamentally, and the long-term plant growth still cannot survive, or some only select relatively simple saline-alkali-tolerant tree species for planting. Contents of the invention [0004] Purpose of the invention: the present invention aims at the deficiencies in the prior art, and proposes a method of coastal tidal flat cultivation of one hundred kinds of saline-alkali-resistant tree species, which changes the singleness of ...
