Specialty Introduction
The soil Remediation Research Institute is mainly engaged in the improvement of obstructed farmland soil, improvement of saline-alkali land, enhancement of poor soil quality, protection of black soil, high standard farmland soil fertilization, as well as the research on the utilization of the agricultural waste. In the field of salinization-alkalization land improvement, research has been conducted on alkali adjustment, salt resistance, reduction of soil obstacles, construction of a healthy soil system, and improvement of soil quality. After a decade of study, four core technologies have been formed: directional control of water and salt transport, safe consumption of sodium content and saline-alkali obstacles, soil fertilization, and green agricultural bio-efficiency. A saline-alkali land improvement model has been established for inland soda areas, coastal beach areas, Hetao River Basin, and northwest arid areas based on soil characteristics, and soil conditioners and biological agents from chemical and biological sources have been developed accordingly. This has led to an integrated improvement approach consisting of "scientific quick diagnosis," "targeted improvement plans," "specialized techniques + customized products," and "professional guidance steward services."
Over 40 national, provincial, major scientific and technological investment projects, municipal projects, and parallel projects have been leading the organization of the provincial industry-university-research alliance, "Liaoning Province Facility Agriculture Soil Health Technology and Application Industry-University-Research Alliance" and the municipal industry-university-research alliance, and the "Liaoning Shenyang Chemicalized Farmland Soil Quality Improvement Industry-University-Research Alliance", which led to the approvement of the Shenyang Soil Health Technology Innovation Center. Twenty national authorized patents have been obtained, nine technical standards have been formulated, and related achievements have won the first prize of Liaoning Province Science and Technology Progress, the first prize of China National Chemical Corporation's "Innovation Cup" innovation and creativity competition, the third prize of China National Chemical Corporation's scientific and technological progress, and one excellent project in Shenyang's major technical challenge tackling activities, reaching the international advanced level in overall technology. Shenyang Research Institute of Chemical Industry has developed three types of improvement products with independent intellectual property in biological, chemical, and biological-chemical coupling, obtained 15 fertilizer registration certificates, and certified four new fertilizer products in Liaoning Province. These technological achievements have been applied and demonstrated in more than 30 towns and townships in nine provinces including Liaoning, Jilin, Heilongjiang, Inner Mongolia, Xinjiang, Gansu, Ningxia, Shanxi, and Shandong, with a promotion area of 30.6 million mu, radiating and driving 90 million mu of surrounding land. Demonstrative field soil structure improvement, microbial activity enhancement by 3-5%, saving of about 5 kg/mu of chemical fertilizers, reducing soil alkalinization by 5-10%, 30-50% reduction on new reclamation land, average yield increase of over 10% on original cultivated land, and over 50% increase in yield on new reclamation land compared to conventional improvement methods by farmers have been achieved through improvement."
The investigation and remediation of contaminated sites is mainly aimed at relocating contaminated sites in chemical factory, mining polluted site, pollution of farmland, to conduct field investigation, risk assessment and soil remediation and formed the electric remediation technology, microwave hot repair technology, plasma high voltage pulse discharge soil remediation technology. We established the research and development platform of new soil remediation technology with soil remediation technology. The main research direction include site environmental investigation, contaminated site investigation and risk assessment, and formulate technical plans for remediation of contaminated sites. The company has completed a number of site environmental investigation and risk assessment projects in Liaoning, Hebei and other places.
Technical introduction
1、Saline-alkali soil improvement
Aiming at the problem of saline-alkali soil high pH, high salt content, low effective phosphorus, a single soil structure, fragile ecological environment, inhibition of crop growth, we build the technology to decrease the pH, improve soil structure, regulate the soil rhizosphere environment, promote soil fertility, and improve crop quality. Our technology has been applied in Heilongjiang, Jilin, Liaoning, Ningxia, Inner Mongolia, etc. The accumulative application area has reached more than 10000 mu.
2、Acid soil improvement
Aiming at the problem of acid soil low pH, low base saturation, low available nutrients, low beneficial microbial activity and active aluminium poisoning, we build the technology to reduce soil acidity, enhance soil fertility and increase crop yield, improve crop quality. At present, the technology has been applied in Hunan, Jilin province.
3、Sandy soil improvement
Aiming at the problems of poor water and fertilizer retention ability, low organic matter content and poor microbial habitat in sandy soil, an integrated technology was established to improve microbial community structure, improve soil water and fertilizer retention ability, promote soil nutrient circulation, improve crop yield and improve crop quality. At present, in Inner Mongolia area demonstration promotion area of more than 1000 mu.
4、Black land protection
In order to solve the problems of "thinning", "thinning", "hardening" and "biological decline" of black soil, two sets of key technologies for improving the quality and efficiency of black soil and three types of new environment-friendly soil fertilizer products were constructed, which can improve soil organic matter, enrich soil microbial community structure, and achieve soil quality improvement and sustainable agricultural development of black land.
5. Continuous soil improvement
In view of the prominent obstacles such as poor soil quality, crop yield and quality decline in continuous cropping, composite microbial agent products with high concentration and high activity were developed to improve the quality of soil hindered by continuous cropping, enhance crop resistance, increase crop yield and improve crop quality, so as to achieve green, high-quality and sustainable development of continuous cropping plants.
6、Investigation and risk assessment of contaminated sites
For chemical industry, thermal industry, thermal power industry and other relocation sites to conduct investigating, sampling, testing, analysis, according to land planning and utilization functions, according to the relevant standards to determine whether the soil pollutants exceed the standard, such as exceeding the standard, it is considered that there may be health risks, then carry out a detailed investigation, and give a remediation project.
Product introduction
Developed more than 10 kinds of soil conditioner products, functional organic fertilizer products, microbial agent products, and obtained the fertilizer registration certificate issued by the relevant Ministry of Agriculture.
Three kinds of bio-based fertilizer synergist products have been developed, which can be added to compound fertilizer, liquid water-soluble fertilizer and solid water-soluble fertilizer.
