Problems solved by technology

[0008] But above each kind of method all exists more or less shortcoming, and each kind of way basically all is a temporary solution but not a permanent cure when used alone, also generally is to take wherein a small aspect to carry out partial governance in the prior art; Therefore, a scientific and effective comprehensive management method is needed to improve the saline-alkali land, fundamentally improve the saline-alkali land, and then use the improved saline-alkali land to plant corresponding economic crops, maintain and improve the improvement effect and bring economic benefits

Abstract

The invention discloses a method for rapidly improving a severe saline-alkali wasteland. The method comprises the following steps that ditches are dug in planting plots to form drainage channels and planting areas; gravel layers are laid in the planting areas, salt discharge pipes are laid in the upper portions of the gravel layers, back-filling soils are used for covering the upper portions of the salt discharge pipes to form planting layers, and washing salt with fresh water is carried out; the soils are deeply plowed, leveled and fertilized, Sophora alopecuroide is planted in the first yearand the multiple cropping of oil sunflowers and corns is conducted in the second year for improving saline-alkali soils by physical, chemical and biological methods so as to achieve the dual purposesof saline-alkali soil improvement and economic benefit increase. The method for rapidly improving the severe saline-alkali wasteland has green, environmentally friendly and pollution-free process ofimproving the saline-alkali soils and prominent improvement effect. The improved saline-alkali soils can produce economic benefits in the same year and have good economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, in particular to a method for rapid improvement of severe saline-alkali wasteland. Background technique [0002] At present, there are mainly the following technical measures for the transformation of saline-alkali land: [0003] 1. Water conservancy improvement, salt washing with fresh water: suitable for well-drained areas with high terrain. [0004] 2. Biological improvement: improve the micro-ecological environment of saline-alkali land, apply bio-organic fertilizers, supplement organic matter, and increase the number of beneficial microorganisms in the soil, so as to establish a new micro-ecological balance between soil, plants and microorganisms in saline-alkali land, and achieve the goal of biological control. [0005] 3. Chemical improvement: apply about 15 tons of gypsum per hectare, and apply it once as a base fertilizer. It can also be combined with the actual l...
