Introduction
According to the requirements of the "National High-Standard Farmland Construction Plan (2021-2030)", in order to promote the technical experience of improving my country's saline-alkali land, we have
Finalize this document.
Improving saline-alkali land is of great significance to ensuring national food security and protecting the ecological environment. In order to solve the problem that a single technology is difficult to satisfy the salt
To solve the problem of demand for improving saline-alkali land, my country has developed three key technologies. iron tailings improvement, fishery-agriculture coupling, and biological improvement to improve saline-alkali land.
Long-term effectiveness and high efficiency, thereby promoting efficient and high-value utilization of improved saline-alkali land. GB/T 42828 aims to provide relevant parties with three types of salts
The requirements and effect evaluation methods of alkaline land improvement technology are planned to be composed of three parts.
---Part 1.Iron tailings improvement. The purpose is to use iron tailings from stable sources and safe quality as saline-alkali soil improvement materials and standardize iron tailings.
Sand improvement technology not only achieves large-scale and standardized improvement of saline-alkali land, but also ensures soil environmental quality and food security, and promotes
Promote sustainable development of agriculture.
---Part 2.Improvement of rice fields, ponds, fisheries and agriculture. The purpose is to provide solutions for saline-alkali land improvement using the saline-alkali land rice field, pond, fishery and agriculture model.
Provide technical guidance and improvement effect evaluation basis, solve the problem of the outlet of salt washing and alkaline water discharge during the treatment of saline-alkali land, and achieve ecological benefits.
It can achieve win-win benefits and economic benefits, and promote the comprehensive utilization and sustainable development of saline-alkali land.
---Part 3.Biological improvement. The purpose is to use biological resources such as microbial fertilizers, organic fertilizers and straw, as well as to plant green manure and resistant crops.
The saline-alkali land improvement carried out by biotechnology such as halophytes provides technical guidance and improvement effect evaluation basis, protects land resources, increases
economic benefits and promote the comprehensive utilization and sustainable development of saline-alkali land.
General technology for improvement of saline-alkali land
Part 1.Iron Tailings Improvement
1 Scope
This document describes the technical principles of saline-alkali land improvement technology with iron tailings, and stipulates technical requirements, field management and effect evaluation.
This document is applicable to iron ore mining enterprises that use high-silicon iron tailings obtained after crushing, grinding, and magnetic separation physical processes to treat hardened and transparent minerals.
Improve the saline-alkali land with poor soil properties and loamy soil texture.
This document does not apply to improvements where the soil texture is sandy or sandy loam.
