“the implementation of the integrated use of saline is of strategic importance for ensuring national food security and securing chinese jobs.”
— on 21 october 2021, general secretary xi stressed during his visit to camp shandong
Food security is the “big man” and cropland is the lifeblood of food production. Salted land is an important source of “extension, expansion, efficiency”. The “recommendations” of the 20th plenum of the party's 4th session stated: “enhanced protection of black land and integrated use of saline land to improve the quality of arable land”
From the yellow river delta high-tech industrial demonstration area in the eastern camp of shandong, to the dry-alkali fields in the hoang dynasty city of hebei, to the modern agricultural demonstration park in the bayan ghur city of inner mongolia, the general secretary of xi has given high priority to the use of salin complexes and has made several visits to the salin regions。
The formation of saline began with a “salin migration”. The hot sun's exposure and man-made disturbances, among other things, led to the “crawling” of salt below the ground, which competed with crops and tied the soil。
There are 1. 5 billion acres of saline in the country, 500 million of which have potential for exploitation. “the implementation of the integrated use of saline is of strategic importance for ensuring national food security and securing chinese jobs.” the generous advice of general secretary xi is being translated into practical action by the regions and sectors concerned。
The size, variety and wide distribution of our saline lands require, first and foremost, a “precision of the veins”. The third national land survey essentially determined the extent and size of the existing saline land distribution in the country; in 2021, the ministry of natural resources conducted an evaluation of the national cropland reserve resource survey to assess the suitability of saline land for development into arable land on a plot-by-lot basis to support the scientific rational use of saline land。
With the bottom, it's "open"。
The rice demonstration plot for the rehabilitation of heavy salinized land in the town of taishan, grande an, jilin, was measured and average acre production exceeded 600 kg, close to the level of good land on black land。
“most of this area is a soda salin and the soil is very dense. It is thanks to organic silicon improvement agents that crops can take better root and grow on a home-grown, loose-earthed salt”. The deputy to the soil fertilizer station in jilin province said zaiyong。
Technologies such as aluminum sulphate improvement, devulcan plaster and phosphorus plaster improvement have also been explored locally for soda salin. To date, the city has implemented 27 salinization projects, adding 1,957 acres of arable land and increasing food production capacity by 235 million pounds per year。
The saline changes are taking place in many places。
In gua county, gansu springs, water fertilization techniques are dripping, fertilizing and changing the soil to “strength” the sandy salinized soil that is common in the north-west; the east camp reclamation zone uses the upper vacuum pump for the management of the salin in the coastal salin, sucking out the subsurface salt like a “sort” ... In recent years, measures have been adopted to increase the upgrading of saline land, so that marginal land can be given a chance to thrive。
In the end, saline is managed so that it can grow. Locally, the selection of saline-resistant specialty varieties has been accelerated, promoting “new owners” of saline with a combination of “sapling” and “land-appropriate” species。
The national saline complex, located in the east camp city, utilizes the technology innovation centre, where breeding laboratories are capable of precision control of wind, light, temperature, water, nutrients and gas and produce six to eight generations of crops a year at a much faster rate than the field。
“the centre has continued to strengthen basic research, such as seed resources, and has played a key role in scientific and technological innovation by nurturing 68 new varieties of saline-resistant crops and registering 20 new varieties of saline-resistant crops.” the chief of the science, technology and innovation department of the yellow river delta agricultural high technology industry demonstration area in shandong province, yang jun。
At the national level, the ministry of agriculture and rural development has in recent years organized a coalition to combat saline-resistant crop breeding, carried out precision identification of saline-resistant resources for 12 crops, carried out the initial excavation of 143 excellent genes, screened more than 1100 saline-resistant resources and promoted 711 saline-resistant saline-resistant saline-pregen resources。
A grain of “gold seed” leaves the laboratory and sows it into saline land, raising farmers' well-being。
In the salinous terrain of nampi county, hebeigu county, yellow wheat flows with the wind. "i planted 1,000 acres, all small 60s, volts, saline, 1,000 pounds of acre." the head of the professional cooperative for luminous grain cultivation is confident. For the time being, the first four saline-resistant wheat varieties approved by countries, including “small 60”, have reached an area of over 300,000 acres。
Today's saline land is not just a barn, but a fertile ground for the flourishing of industry. In recent years, sites such as hebei, inner mongolia and shandong have been included in the pilot integrated utilization of agricultural land reserve resources such as national salin lands, which, with financial, technical and other support, offer a promising combination of salin lands。
The old poor, poor salinized lands are now growing and growing, with abundant grains showing their diverse values. The salinization of the land as a “moderate of hope” and the strengthening of china's wage base, which is a reflection of its long-standing commitment, are the most profound responses to this land。
