Abstract

The invention belongs to the technical field of soil improvement, and particularly relates to a planting method suitable for saline-alkali soil remediation and improvement, in the planting method, a first planting fertilizer layer with a preset thickness is laid at the bottom of a planting hole or a planting ditch, so that on one hand, moisture and nutrient loss is blocked, moisture and nutrient leakage is prevented and controlled, and soil remediation and improvement are facilitated; on the other hand, the water and soil conservation and leakage prevention effects are achieved, and later-period nutrient and fertilizer requirements of plant crops are met; after soil in the planting holes or soil in the planting ditches and planting fertilizer are fully and evenly stirred according to a preset proportion, backfill soil is formed and then backfill planting is conducted, and the growth nutrient and fertilizer requirements of planted crops are met; after a second planting fertilizer layer with the preset thickness is laid below the surface soil again, the surface soil is covered, and the effects of preventing salt from accumulating on the ground surface and permeating into the planting area and delaying water evaporation are achieved; by the adoption of the technical scheme, the purpose of restoring and improving the saline-alkali soil can be achieved only by simply adjusting and changing the planting method.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a planting method suitable for soil restoration and improvement in saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation land. The salt contained in the soil will affect the normal growth of crops. In severe saline-alkali land, plants can hardly survive. Therefore, the restoration and improvement of saline-alkali land is regarded as a systematic project. [0003] The currently used saline-alkali land restoration (improvement) methods mainly include: [0004] Water Improvement Act. First of all, water conservancy improvement of saline-alkali land requires the establishment of a complete drainage and irrigation system to separate drainage and irrigation. It is also necessary to strengthen water management, strictly control the groundwater level, and continuously wash and remove the salt in the soil through irrigation and flus...
