"Black Land Guard": Guarding the Black Earth Grain Grain

Author:Jilin Daily Time:2022.07.27

Black soil protection is inseparable from the promotion and application of protective farming models. For more than a decade, a group of experts from the Chinese Academy of Sciences have been engaged in black soil protection on the land of Jilin. Let's get to know them together!

Due to long -term unreasonable farming and over reclamation, the black land becomes thinner and thinner, which brings challenges to the sustainable agricultural development. In order to change this situation, scientific researchers have been fighting for a long time, and have developed a "protective farming" model suitable for the black land suitable for the northeast of my country. Recently, continuous rainfall, they often go to the field for physical examination for soil and corn, mainly to monitor the soil's nutrients, temperature, and weight indicators.

"The problem of soil is thinning, thinning, and hardening. As long as the wind erosion water erosion is controlled, the problem of thinning the climate will be solved. After the straw is returning to the field, it will become organic matter and transform into soil fertility."

"Ten years ago, we came here to engage in protective farming and research and development. At that time, the people did not recognize us. They thought we were the theoretical school of talked about soldiers on paper. In fact, ordinary people care about the size of their corn sticks and the level of yield. Protective farming technology has been continuously communicated with the people, and the corresponding supporting agricultural machinery and agronomy measures will be improved to achieve a true high -yield and efficient protective cultivation model. "

In 2021, the Yahu Model R & D Base Corn ultra -high -yield test fields have reached 1077 kilograms, setting a record in the Northeast region of super tons of food for 4 consecutive years. This year, the entire Jilin province implemented a protective farming area of 32 million acres, an increase of 4 million acres from last year. Researchers will continue to "write the paper on the ground"!
