Erosion on agricultural areas in Inner Mongolia, positive recommendations for conservation tillage

Question an important part can not be ignored. We think. The topsoil can be cultivated the soil surface wind blew free, mainly due to the traditional fall plowing. When the autumn after harvest will generally have to turn that next year the only way conducive to farming. But if not keep up with plowing the manor after the rain, and farming the soil surface and there is no covering protection, full nudity, will be subject to the erosion of the winter monsoon, the soil organic matter in the surface dust and blow away, this time not only polluted the air, will result in soil desertification, soil fertility decline. Year after year, growing desertification, resulting in deterioration of ecological environment each year,[link widoczny dla zalogowanych], dust storms every year. So to solve this problem, in addition to stop cleared for farming, deforestation, taken for Green and other protective measures, but also on the field to change the traditional farming methods, the implementation of conservation tillage. 2 to local conditions to take a different approach in implementing conservation tillage 2.1 Yin, Yanshan hilly agricultural areas wind erosion and desertification, in addition to Grass, the continued cultivation of the land should be taken to tillage. That the land does not fall turn, stubble through the winter. Every 1 to 2 years, go for a full range of land deep loosening, so the soil can reduce the monsoon wind, whilst maintaining a winter snowfall, which will help the second sowing in spring to reach the goal of zero tillage can increase production of anti-wind erosion and desertification effect, the key technology is the no-till seeding and full of deep loose. No-till seeding is a mature technology in foreign countries. They are mainly in a joint operation unit, a complete break crop, rotary tillage, planting, fertilizing, repression and other operations,[link widoczny dla zalogowanych], so the crew is generally more than 160 horsepower tractor. The joint operation of foreign machines, we can introduce a small amount of experiment and demonstration, and absorb the essence; lot must be based on our national conditions, can be broken in the domestic crop planter, planter in the selection test, improve infrastructure, and develop a reasonable operating standards, after a pilot demonstration after the success of the Yin, Yanshan Hill Erosion agricultural areas. Avoid compaction of arable land in order to prevent infiltration of rain, every 1 to 2 years can go for a full range of subsoiling. It features: �� to maintain vegetation, while land deep loose, but still protect the cultivation of vegetation to prevent wind erosion desertification of the soil surface; �� loose depth, and can be subsoiling to 3O ~ 50cm, is conducive to water infiltration and storage. If the technology in the Yin, Yanshan hilly area full implementation of the several thousand mu of cultivated land can be protected, to reduce or avoid wind erosion and desertification of arable land. This not only makes our region to curb the deterioration of ecological environment and improve each year and can restore the fertility of arable land, access to ecological and economic benefit. 2.2 for some of the irrigated water irrigation, beaches, etc., can gradually be extended ridge, the shift from the traditional plowing the land for the disc plow spade plow land. Ridge is characterized by ridge to furrow wind can play a role in the spring after sowing, the protection due to ridge, furrow in an increase in temperature and humidity are conducive to crop seedling growth, reducing wind erosion. Disc plow farming is characterized by: �� plow bottom is a wavy cross-section, is conducive to breaking the plow pan, which will help water seepage. �� surface vegetation cover is incomplete, uneven surface after tillage, it is a good anti-wind and sun mattress. �� disc plow plowing for the rolling operation, without crashing soil mattress, less power consumption, save operating costs. 'These technologies are mature, the main task is to step up publicity to let people change their concepts, the introduction of new machinery, well the experimental demonstration, gradually realized the advantages of conservation tillage. 2.3 promote the protection of cultivation, as in the past has been to promote the application of plastic film mulching technology. But to focus on the following two tasks: �� plastic film recycling. After the plastic film mulching to improve recycling and reduce the white pollution; �� plastic film recycling should be in the spring before planting to reduce soil erosion in winter. 3 advantages of conservation tillage and suggestions from the main contents of conservation tillage can see the advantages of the implementation of conservation tillage: 3.1 Land conservation tillage is the implementation of a technical measures to prevent wind erosion and desertification,[link widoczny dla zalogowanych], the role of anti-wind erosion and desertification large, wide area effect. t3.2 conservation tillage not only against the land from wind erosion, but also conducive to fertilizer, water, you can get two-stroke, to the effect of increasing production. 3.3 Some of conservation tillage technology in farming based on traditional practice, and invest less significant effect of increasing production and income of farmers is easy to accept. In conclusion, conservation tillage is less investment, good effect, farmers are willing to accept an ecological construction projects. Proposed regional government in the Grain for Green Project launched, ecological resettlement project,[link widoczny dla zalogowanych], the Three-North Shelterbelt Development projects at the same time, the organization of agriculture,[link widoczny dla zalogowanych], agricultural and other departments to promote the implementation of comprehensive conservation tillage agriculture projects to speed up the pace of ecological construction, to ensure the sustainable agriculture development so that the beautiful landscape of Inner Mongolia early realization of the grand goals.
