CCTV News: Chongqing's existing arable land area is 28.05 million mu, and some arable land is seriously acidified.To this end, a local exploration of the quality of land improvement has been explored to improve the quality of cultivated land.
Lou Biqiang is a large rice plantation in Nanchuan District, Chongqing.The staff is asking for the increase in rice and sorghum after using soil improvement agents last year.In 2020, Lou Biqiang circulated more than 400 acres of land for the planting of grain and oil crops. However, the harvest of the year splashed cold water.
The pH value is lower than 5.5, which means that the cultivated land is acidified, and the amount of fertilizer after acidification of cultivated land is also limited.To solve this problem, the local government gave Lou Biqiang a soil improvement agent.
By driving the demonstration project, in 2021, Chongqing's acidified soil management was promoted by 2.139 million mu, and rice yield was increased by more than 8%.
