On january 9th, zhongchongcheng (journalist guo jia) journalist learned from the north east institute of geography and agro-ecological research of the chinese academy of sciences that china's first national sutter water fields adaptation industry standard — “ny/t4979-2025” — will be officially implemented on may 1 this year。
On 9 october 2024, in the town of jilinbashi, the site of the survey of the “black earth barn” technical conference in the great an model area, the right side of the paddy field was an improved field and the left side of the paddy field was an unimprovised saline plot. Photo by guo jia
The standard, which was drafted by the north-east institute of geography and agro-ecological research of the chinese academy of sciences in collaboration with the crop quality monitoring and protection centre of the ministry of agriculture and rural affairs and the agricultural rural department of jilin province, applies mainly to soda salin lands, including areas with high soda salin content, such as the three north-eastern provinces, a coalition and the ningsha river。
For the first time at the national level, the standard systematically establishes a three-pronged technical system of integrated and coordinated governance, namely, the “good fields + good castes + good practices”, defines the steps and methods for the national salinization and use of the field, including the operational norms for the rehabilitation of the land, the selection of good species, the integration of good practices, etc., and proposes retroactive methods such as food production capacity objectives and record keeping。
The key benefit of the successful development of the standard is the economically viable breakthrough in the “good fields” — acid phosphorus plaster conversion techniques. Phosphate is a by-product of the phosphorous fertilizer industry, which is acidic, effective and soil-high ph, and contains calcium ions that can be replaced with harmful sodium ions that result in soil sheeting, reshaping soil structures, creating “healthy living” conditions for crops and eventually achieving high yields。
As the first drafter of the standard, a researcher at the north-east salt sub-centre for the integrated use of salted lands of the national centre for technological innovation stated that the implementation of the standard would serve as an important technical basis for the development, construction and acceptance of national and local projects for the integrated upgrading of salted lands and would provide a unified framework for the development of more targeted local standards at the local level.
