Embodiment Construction

[0033] A method for greening vegetation in highly saline-alkali areas based on growth nutrient space, comprising:

[0034] Including the following processes:

[0035] (1) Select the plant species;

[0036] (2) Determine the lower limit value D (cm) of the horizontal and vertical distribution range of plant root nutrition.

[0037] (3) Calculate the lower limit L (cm) of the distribution range of plant root nutrition level.

[0038] (4) Determine the nutrient space W (cubic centimeter) of each plant species, and the nutrient space of the plant is calculated by the following formula.

[0039] W=π×(L 2 )×D; the occupied space of plants is determined by the horizontal distribution of the root nutrient space, which can be divided into two cases. Considering the planting hole, the occupied area A=π×(L 2 ) (square centimeter) is considered as a square, A=(L 2 ) (square centimeters).

[0040] (5) Analysis of soil thickness and groundwater level in saline-alkali soil

[0041] As...

Abstract

The invention discloses a highly salinized region greening vegetation method based on a growth nutrition space. The method comprises the steps that 1, selecting plant varieties; 2, determining a lowerlimit value D of a horizontal and vertical distribution range of plant root nutrition; 3, calculating the lower limit value L of the plant root system nutrition level distribution range; step 4, determining a nutrition space W of each plant seed; 5, the saline-alkali soil layer thickness and the underground water level are determined; 6, calculating the minimum space under different plant configurations by applying a multi-objective programming optimization algorithm; the technical problems that in the prior art, the optimal growth nutrition space needed by plants is not considered in a rootzone limited cultivation mode, the nutrition space is too large due to growth, the investment cost is increased, or the growth nutrition space is too small, and later growth of the plants is not facilitated are solved.

Description

technical field [0001] The invention relates to saline-alkali land greening and planting technology, in particular to a method for greening and planting in highly saline-alkali areas based on growth and nutrient space. Background technique [0002] At present, in the greening of saline-alkali land, the root zone-limited cultivation mode is adopted to place the tree root system in a controllable range and isolate it from the external saline-alkali environment, which has the advantages of efficient use of fertilizer and water and high survival rate. The optimal growth nutrient space required for growth will lead to excessive growth of nutrient space, increasing investment costs, or too small growth nutrient space, which is not conducive to the later growth of plants. Therefore, how to determine the lower limit of the growth nutrient space required by plants is of great importance. Sex speaks for itself.
