Protect Black Land Jilin Province Promoting the "Pear Tree Mode" upgrade

The summer wind blows across the field, the corn's leaf is loud, and the layers of green leaves are rolling like waves.

In the core demonstration area of ​​Millions of Green Food Raw Materials (Corn), a national millions of acres of green food raw materials (corn) in Jilin Province, Wang Guiman, the head of the agricultural technology promotion general station of Lishu County, is looking at the growth of corn.

"Today, the" pear tree model "has achieved leapfrog development. The promotion area has grown from 1.5 million mu in 2020 to 2.32 million mu in 2021. It is expected to achieve 2.8 million mu in 2022!" Wang Guiman said.

Lishu County is located in the ingots of the Songliao Plain, known as the "Golden Corn Belt" in the world, and is an important grain -producing county in China. Since 2007, Lishu County has explored and implemented the protective farming "Lishu Model" with the main content of "straw coverage and plowing" as its main content, which provides the "Lishu Plan" for the protection and utilization of black soil.

In recent years, in terms of exploring and innovating the "pear tree model", pear trees have created an upgraded version of the modern agricultural production unit. The new types of business entities such as farmers' professional cooperatives or family farms are used as the main body to break the boundaries between farmers and households. The concentrated continuous films are a unit, mechanized operations in the process, maximize the role of agricultural machinery, and promote the implementation of the "pear tree model" throughout the county.

"Through the construction of modern agricultural production units, the production pattern of cooperatives is the main body, the government -led, the food trade, finance, and agricultural professional service organizations, so as to achieve scale, standardized row spacing, smart planting, and coordination of production and sales, and take the lead in achieving the first realization of realization. Modern agricultural standardization, mechanism, informatization, and contractualization. "Wang Guiman introduced that Last year Lishi County completed the construction of 14 units and planned to reach 22 units this year.

At the same time, Lishu County cooperated with the Chinese Academy of Sciences to complete the construction task of the Lishu Demonstration Zone with high quality of the 10,000 acres of "Black Earth Grain Grain"; cooperated with China Agricultural University to carry out the "One Hundred Bojin Baijia Cooperatives" operation; The Academy of Agricultural Sciences of the Shuxian County carried out scientific and technological research around seeds, agricultural machinery, and agricultural technology, and continued to improve the innovation, demonstration, and leading of the "pear tree model".

This year, the "Pear Tree Model" is based on the 4 protective farming models of the original corn straw covering exemption, corn straw covered with rotation, corn straw covering the original ridge planting, and the height of corn straw. The "change of meat" project is incorporated into the field model of straw science to leave fields and dung piles, creating an upgraded version of the "4+2 Pear Tree Model" with more cost -saving and efficiency.

Data show that in 2021, the yield of the pear tree demonstration base reached 1077 kilograms, setting a high -yield record in the Northeast region. In 2022, Jilin Province was optimized and promoted the "pear tree model", and 46 counties (cities, districts) promoted a protective farming area of ​​32.83 million mu.

Today, the protection area of ​​black land in Jilin Province ranks first in the country. The annual protective farming area of ​​more than 10 million acres is added each year.
