"Continuously push the cause of Jilin's revitalization and development" technology helps protect the black soil granaries

Technology helps protect the black soil granary

Gaojia Village, Lishu County, Jilin Province, a more than 200 acres of test fields, in the heart of Yang Qingkui, the head of the peasant professional cooperative of the Kangda Agricultural Machinery Machinery in Lishu County, is a treasure land.

"At that time, this was a low -yielded field that no one was willing to plant." Yang Qingkui led the cooperative to try new technologies covered with corn straw on this land. earthworm. This new technology later had a loud name- "Pear Tree Model", and this test field became the longest protective farming research and development base in China.

"Science and technology help, we have achieved over -tonnage for 4 consecutive years." Last autumn harvest, Yang Qingkui lamented when we saw the result of 1077.94 kg per mu.

The "Pear Tree Model" windproof soil, fertilizer land, drought resistance, and cost -saving efficiency has become the consensus of more and more local farmers.

This year, Jilin Province optimized and promoted this model, promoting the protection area of ​​32.83 million acres, and the suitable area was fully implemented.

In recent years, Jilin Province has explored the establishment of a variety of black soil protection models through the protection paths such as the east of the Eastern Anti -soil, the improvement of the quality of the central region, and the improvement of fertilizer and the improvement of fertilizer in the west. At the Changling County of Songyuan in western Jilin, the Director of the Northeast Geography and Agricultural Ecological Ecological Ecological Ecological Ecology of the Chinese Academy of Sciences has built 500 acres of demonstration fields.

Last year, Jilin Province signed an agreement with the Chinese Academy of Sciences to fully implement the "Black Earth Greece" science and technology conference, and will build 3,000 acres, 30,000 acres of demonstration bases and a number of demonstration sites. At present, the province's exemption and sowing machines have reached 35,000 units, demonstrating the promotion of nearly 500,000 acres of straw and mixed fields, which is equivalent to the sum of the past three years. The rice bean wheel is used as 1.5 million mu, and the saline -alkali cultivated land treatment model is more than 300,000 acres.

"Tibetan grain is in the ground, hiding grain in technology, and protecting the black land, which is of great significance." Yang Qingkui said.
