Abstract

The present invention provides a method of performing original soil greening on sulfate-containing sandy soil by using vermiculite-containing nutrient soil, comprising a nutrient soil applying step. The nutrient soil applying step comprises applying the nutrient soil, and the nutrient soil comprises the following components of lateritic soil, vermiculite powder, broad-leaved tree deciduous leaf soil, NPK compound fertilizer, limonite, rose-boot extract, furi acid, akebia stem root powder, corncob powder, brown bean pulp, yellow serofluid, carp powder, decomposed pigeon excrement, water-retaining agent and trace elements. The present invention also provides a preparation method of the nutrient soil. According to the plantation method, the expense of carrying new soil is saved, the cost is reduced, the expense is saved by 36%, and the effects of reducing content of free ions in the soil and increasing dealkalization rate of the soil is achieved. The leaf transpiration rate of planted fraxinus is 3.7-6.4 [mu]mol / (m2.s).

Description

technical field [0001] The present invention relates to a kind of method that adopts nutrient soil to carry out native soil greening on sulfate-containing sandy soil, in particular to a method that uses vermiculite-containing nutritional soil to carry out original soil greening on sulfate-containing sandy soil, The invention belongs to the technical field of original soil greening of saline-alkali land. Background technique [0002] The saline-alkali land area in the world exceeds 900 million hectares, and the saline-alkali land of various types in my country reaches 100 million hectares. The improvement of saline-alkali land is a worldwide problem. Saline-alkali land is a part of my country's important land resources, and saline-alkali soil occupies a large proportion of wasteland resources. The saline-alkali land in the northern coastal areas of my country is mainly distributed in the Bohai Rim, including the Yellow River Delta along the Laizhou Bay, the sedimentary plain...
