Jilin: The improved area of saline -alkali land increases the area of "eight hundred miles"

This year, Jilin Province's grain planting area exceeded 88 million acres, a record high. The new cultivated land mainly comes from the western Jilin region, known as the "eight hundred miles". In recent years, with the continuous advancement of the comprehensive land governance project of Jilin Province, a large amount of saline -alkali land has been improved, and the past nonsense land is gradually becoming the growth pole of grain production in Jilin Province.

In Xinhean Town, Da'an City, Jilin Province, the continuous rice has grown well and has entered the dumping period. But just before the spring plowing this year, it was another scene.

The transformation of this "Mi Ganchuan" is not only a witness, but also the person in charge of one of the projects. "Change" cultivated land from salt -alkali land, soil improvement is the key. The cooperatives where Meng Xiandong is located mainly uses physical, biological and other methods to improve salt -alkali land, use quickly dilute the surface layer, create the technology of ripening and cultivating layers, add organic fertilizer to the soil additives, and then use rice alkali to cure alkali and water with water. The way to turn the barren saline -alkali land into a mature rice field

In recent years, Daan City has continued to cultivate in exploring salt -alkali land governance technology and path. Many technical units have practiced related technologies in the province, and some have taken root for more than 10 years. Last year, Jilin Province also signed the "Battle of Black Earth Granary Science and Technology" with the Chinese Academy of Sciences, and established a salt -alkali land to improve the 10,000 acres of demonstration zone in Da'an City, bringing valuable salt -alkali governance experience to Daan.

At the same time, scientific researchers have also tapped the potential of the farming industry in the aspects of salt reduction, fertilizer and land, and innovation and demonstration of the efficient improvement and utilization technology of salt -alkali fields with "nourishing and changing land, first care, and breeding". Realize the quality of cultivated land and grain output. There is a 24 -acre test field in the Niuxin Caifu Farm in Da'an City. Researchers at the Northeast Geography of the Chinese Academy of Sciences are sampled the soil and water in the rice fields. After several years of research and practice, 18 technical solutions have been integrated in these 24 acres of test fields.

The saline -alkali land in Da'an City is distributed in 18 towns and villages in the city, and once "stuck" the pulse of local agricultural development. This year, under the guidance of the Jilin Provincial Department of Natural Resources, Daan City established a demonstration base for comprehensive utilization of saline -alkali land, and introduced 9 saline -alkali -improvement technology units to explore the technical exploration of saline -alkali and land improvement, providing technical support for the improvement of saline -alkali improvement in the future. This year, through the implementation of a comprehensive land rectification project of the whole region, Daan City will add 1,730 hectares of cultivated land, with a construction area of ​​3341 hectares.
