Embodiment 1

[0016] 1.1 Material: saline-alkali soil, taken from the test site (new tidal flat reclamation land). Nutrient soil (composed of perlite and peat at a ratio of 1:1) was purchased from Huamucheng, Xiaoshan. The matrix material was pretreated as described above.

Abstract

The invention discloses a method for improving a saline-alkali soil matrix for seedling cutting, and belongs to the technical field of seedling cutting soil matrix improvement. The method for improving the saline-alkali soil matrix for seedling cutting comprises the following steps of (1) taking nutrient soil and saline-alkali soil according to the weight proportions, wherein the weight proportion of the nutrient soil ranges from 55% to 65%, and the weight proportion of the saline-alkali soil ranges from 45% to 35%; (2) combining the nutrient soil and the saline-alkali soil in an independent block mode, namely, digging holes in the saline-alkali soil, and filling the holes with the nutrient soil; (3) disinfecting the nutrient soil and the saline-alkali soil. According to the method for improving the saline-alkali soil matrix for seedling cutting, the design is reasonable, operation is easy, the needed matrix improvement measures are provided for in-situ seedling cutting culture or forestation of the saline-alkali land, the survival rate of seedling cutting of the saline-alkali land is increased, the forestation cost of the tidal flat saline-alkali land is reduced, the site environment of the saline-alkali land is improved, the ecological system of the saline-alkali land is improved, local economic development is indirectly promoted, and the income of farmers is increased.

Description

technical field [0001] The invention belongs to the technical field of soil matrix improvement for seedling cuttings, and in particular relates to a method for improving soil matrix of saline-alkali soil for seedling cuttings. Background technique [0002] my country is rich in tidal flat saline-alkali land resources. For a long time, due to typhoons, saline-alkali and waterlogging and other reasons, tidal flat saline-alkali land resources have not been well utilized. At the same time, the excessively high salinity in the tidal flat soil has a certain degree of adverse inhibition, making it difficult for a large number of plants to survive. At present, the coastal shelterbelt system and the typhoon shelterbelt system developed by the forestry system are trying to use forestry technology as a pioneering means to control and stabilize tidal flat saline-alkali land. [0003] Forests are regulators of terrestrial ecosystems, which can effectively improve regional climate and hyd...
