Jilin resumed black land no-till sowing "about"

Jilin resumes black land, no-till sowing

Jilin Province has fertile black land and is one of the world's three “golden corn belts”. However, the “predatory” agricultural production methods have made the fertile black land “tired” and the black soil layer is getting thinner and plowed. The bottom layer is getting thicker and thicker, the more fertilizer is used, and the soil is getting more and more knotted.

“The blade on the planter cuts the soil, draws the location for sowing and fertilization, then the seeds and fertilizer enter the predetermined area, followed by wheel compaction, sowing and fertilization are completed.” Lu Wei’s no-till seeding method makes a large number The straw residue covers the surface and causes the plants to rot in the ground as fertilizer.

“The farmland is implemented with less tillage and no-tillage. The straw is covered with cotton quilts on the ground, directly seeding seeds and fertilizers, the root system is developed, the plants are robust, and the seedling rate is guaranteed.” Wang Guiman, director of the Agricultural Technology Extension Station of Lishu County, said Ploughing and fertilizing soil fertility, water storage and conservation, "alleviated the problem of the spring drought."

The conservation tillage method such as no-till sowing has come. “The land that implements conservation tillage has an average of more than 60 per cubic meter, while the traditional intensive land has only five or six.” Wang Guiman said that the number of alfalfa is an “indicator” for soil ecological restoration, “蚯蚓 for loose planks” The soil has a huge effect, and the root system of corn can be tied to more than 1 meter deep, which can obtain more abundant nutrients, so the yield is higher and the quality is better."

No-tillage sowing and other conservation tillage, selection of fine varieties, integrated pest control... A variety of agricultural technology "integration" applications have allowed Lu Wei to taste the "sweetness" of increasing production. "This set of high-yield technology assembly and integration is greatly reduced. The impact of weather, pests and diseases on agricultural production."

Since last year, Jilin Province has implemented subsidies for conservation tillage technology with straw returning and no-till sowing as the core content, and no-tillage planting technology for straw returning to the field, subsidizing 450 yuan per hectare, and high-grass-grazing The model subsidizes 300 yuan per hectare.
