The technical mode of conservation tillage is in line with the growing habits of most counties in China. Conservation tillage technology is the practice of no-tillage, less tillage, and the use of crop straw to cover the surface, reduce wind erosion, water erosion, and improve soil fertility and drought resistance. The advanced agricultural farming techniques are mainly composed of four key technologies: straw mulching, no-tillage sowing, deep soil loosening, and weed control. In particular, the main crops and modes of cultivation in the northern counties are wheat and corn, which are in line with the protective tillage technology model. The implementation procedures are: wheat straw returning, corn-free (less) tillage, irrigation and field management. Maize artificial or mechanical harvesting - straw returning to cover the surface - deep or loose surface treatment (2 to 4 years) - wheat free (less) tillage - spraying herbicides - irrigation and field management.
Aluminum tripolyphosphate is white powder, insoluble in water, 2-3g/cm3 density, non-toxic, no irritation to skin, no harmful heavy metal elements such as lead and chromium, good thermal stability. It is a new generation of pollution-free white anti-rust pigments and an ideal substitute for lead and chromium toxic anti-rust materials.

The popularization and application of conservation tillage technology have broad prospects: 1) Economic benefits. From the experimental data of conservation tillage and traditional cultivation in Luyang Village, Guyang Town, Guoyang County in the past two years (see Table 1), it can be seen that the implementation of conservation tillage has considerable economic benefits and has a good promotion prospect. 2) Social benefits. The farmers in the project area reflect this technology, save labor, save time, save the province, and save money. The surplus labor force can also engage in other labor and increase income. 3) Ecological benefits. According to the monitoring results, the implementation of conservation tillage can increase the soil moisture content by about 6%, improve soil physical and chemical properties, effectively reduce the air pollution caused by incineration of straw, protect the environment, and contribute to the sustainable development of agriculture. 4) Promote the development of agricultural mechanization. Through the implementation of the project, the county has added a total of 140 exempt (minor) tillage sowing machines, more than 400 corn combine harvesters, 160 straw return farm machines, 300 large-scale tractors and more than 400 soil deep-seasoners. The level of corn production mechanization has rapidly increased. In 2011, after the actual measurement of the land area measuring instrument, the straw returning area in the county reached 26,700 hO, the corn harvested area was 40,000 hO, the soil deep loose area was 16,000 hO, and the no-tillage sown area reached 46,700 hO. 
The problems faced in the implementation of conservation tillage: 1) The publicity and popularization of this technology at the grassroots level is not enough and has not been widely recognized by farmers. Farmers still have doubts about conservation tillage techniques. 2) The protective tillage equipment is not ideal enough. First, tractors with 58.8 kW (above 80 hp) and more than 48.8-horsepower tractors work best in subsea machines, and there are almost no four-wheel-drive tractors of 58.8 kW (80 hp) or more. The second is to use all-around deep-sinking machines to achieve good results. In this county, there are only 10 deep-seam machines in more than 400 deep-steamers, and the remaining 390 machines are deep-slack machines (without wings). The effect is not ideal. Thirdly, the operating efficiency is low. A considerable part of the county's free (minor) tillage planters are not suitable because of adjustment of seed quantity, fertilizer amount, land size and planter's range, and their own factors. 3) In the process of implementing conservation tillage, agronomic and agricultural machinery do not cooperate well with each other, and even disagreements on key technologies have brought certain difficulties to implementation. 4) The agricultural machinery promotion system is not perfect. As the project undertaker, there is a lack of necessary inspection equipment and demonstration bases, and there is a lack of personnel engaged in agricultural machinery technology promotion at the grassroots level.
Promotion of Conservation Farming Feasibility Recommendations: 1) Leaders should pay attention to increasing the administrative driving force of conservation tillage technology. The promotion and application of conservation tillage technology is inseparable from other leaders' attention and support. It is necessary to formulate some preferential policies and to promote the use of this technology as a key task in promoting agricultural income increase. 2) Increase publicity and training. Using television, radio, and internet media, a field conference was held to widely publicize conservation tillage, and farmers in the project area and farmers in the county were trained. 3) The agricultural machinery promotion department should do a good job in the introduction, testing and selection of conservation tillage implements, select the best implements suitable for local conservation tillage to promote farmers, and give purchasers certain purchase subsidy preferences, mobilize the farmers Enthusiasm. 4) Improve the quality of professional and technical personnel, improve the promotion system network construction, do a good job of technical guidance, and do a good job of demonstration and test comparison records. 5) Agronomy and agronomy should be integrated with each other and every technical step must be taken to ensure the smooth implementation of conservation tillage.
