2.3 Establish and improve soil testing and formula fertilization network system During the process of carrying out soil testing and formulating fertilization, Hanzhong City expanded its agrochemical service team, expanded its service network, and actively explored local working methods and service models in light of actual conditions. It was bold in establishing a sound soil testing and fertilizing network system. To innovate ideas and mechanisms, will have a culture, technology, and business integrity of the farmer's store after inspection selection how to determine the soil testing and fertilization of agricultural resources for the supply point, and listed business. On the basis of summing up experience and in-depth investigations, Nanzheng County first selected 26 fertilizer distribution points with strong professional skills, honest and reliable services, and large influence on the production of fertilizers, and created a soil testing formula fertilization and fertilizer supply network. Jingxian County has established a well-distributed fertilizer station as a breakthrough point, insisting on close contact with formula fertilizer production enterprises, and continuously providing revised formulas. It has successively cooperated with three chemical fertilizer production enterprises. Each year, the company produces four major brands and five kinds of crop special fertilizer for the county. 5000t. In Chenggu County, 138 soil-graduating, fertilizer-applied village grading fertilizers were established, and 5 kinds of high-quality, high-quality compound fertilizers with excellent quality were selected. They were organized and supplied at a preferential price, and scientific personnel were selected to enter villages in the key seasons for each fertilizer. The headland will guide farmers to apply scientific fertilization according to the formula fertilization card. Yangxian County and Hantai County made full use of the County Soil Fertility Technical Consultation Service Network to establish village and village soil fertilizer technical guidance branches in townships and villages, and selected farmers with financial strength, technical know-how, and operations to carry out soil fertility technical services, and provide fertilization advice cards and The formula fertilizer purchase concession card is handed over to them, and at the same time, they provide formula fertilizer directly to facilitate farmers to purchase formula fertilizer nearby. In the process of establishing and improving the network system for soil testing and formula fertilization, the counties widely publicized the enthusiasm of guiding and fully mobilizing the fertilizer business households. In the field of soil testing formula fertilization implementation. Widely publicizing and mobilizing each fertilizer store, according to the principle of voluntariness, in each township, select 1 or 2 companies with legal business qualifications, and the types of fertilizers to be operated are qualified products with complete documents. They have certain experience and good reputation in the local area. With the professional service ability, enthusiasm for agricultural services, voluntarily accept the fertilizer station technical guidance and training of fertilizer business households, in order to ensure the quality of service as a starting point. They were recruited to join the fertilizer network, and the soil fertilizer station unified listing guidance services. This will not only improve the soil testing and formula fertilization network system, but also strengthen the team of soil testing and fertilizer application staff. Each county soil fertility station organizes two or more technical training sessions for fertilizer distribution station operators in the off-season fertilizer sales season each year to assess and report on the operation and service status of each fertilizer distribution station distribution point, and to perform non-performance in accordance with the network management methods for the fertilizer distribution stations. Delisting and disqualification of obligations. These measures have laid a good foundation for the smooth development of soil testing and fertilizer application in the city. 2.4 Give full play to the radiation promotion of the demonstration base At the beginning of the formulation of targets and tasks for demonstration bases at the beginning of the year, counties (districts) have selected townships and towns that have developed their own jobs as demonstration models. The counties have also selected counties such as Jing County, Chenggu, and Nanzheng as soil testing and formula fertilization. The landmark demonstration counties regularly organize professional and technical personnel to conduct on-site observation and guidance, organize the people to observe and learn at the scene, and give full play to the exemplary role of the demonstration base. Under the guidance of the Municipal Bureau of Agriculture, the Agricultural Bureau of Nanzheng County and the Soil Fertilizer Station jointly with the relevant agrochemical company held a site meeting of soil testing and fertilization tests, demonstrations, and agricultural product supply and marketing in Nanzheng, through on-site observation, research, etc. Ways to exchange experience with each other, give full play to the role of demonstration demonstration bases in external publicity, and promote the continuous development of soil testing and fertilizer application in the city. 2.5 Strengthen Supervision and Management and Focus on Work Summary The agricultural departments at all levels shall, in conjunction with the financial and quality supervision departments, strengthen the supervision and management of the subsidy funds for soil testing, formula fertilization and the fertilizer market. State-level project subsidy counties and provincial-level project subsidy counties have formulated detailed inspection and acceptance plans for the use of subsidy funds, and have publicly invited tenders for the procurement and installation of laboratory instruments on the Internet. Do it for your money. Hantai District regularly carries out major inspections of the fertilizer market, and the technical cadres of the District Soil Fertigation Stations are responsible for the transportation and technical guidance of the fertilizer organizations. All counties have formulated corresponding soil testing, formulated fertilization and experimental demonstration management methods and rewards and penalties systems. The sample collection, laboratory analysis, formula formulation, fertilizer supply and fertilization, and the demonstration and demonstration work have been implemented to ensure accountability, rights, and benefits. The successful completion of all work. In the process of work development, each county regularly reports to the municipal soil and fertilizer station stage work, corrects existing deficiencies in a timely manner, and at the same time exchanges experience through networks and other forms to further improve the service level. Through the comprehensive development of soil testing and fertilizer application, the current situation of nutrients in the cultivated soil of the project area has been ascertained, farmers’ understanding of soil testing and fertilization has been improved, and the enthusiasm and initiative of scientific fertilization have been increased, and grassroots agricultural technologies have also been strengthened. Promote the network's working ability and cohesion. 3 Thoughts and Suggestions 3.1 Extend the project implementation cycle Soil testing and formula fertilization involves several aspects such as technical departments, enterprises and farmers, and there is a process of understanding adaptation and implementation. The implementation period of the project is relatively short in 3 years and can be under the premise of controlling the total investment amount. Properly extend the implementation cycle so that the research depth, scope of implementation, and technical household occupancy rate of soil testing and fertilization technology will be significantly improved, so that the work will fully play its due role. 3.2 Extend the scope of project implementation Soil testing and formula fertilization is a policy supported by the Party and the government that benefits thousands of families and supports more areas. It is proposed to expand the scope of project implementation, especially for some small food production counties such as old districts and remote and impoverished mountainous areas. It can also be implemented as a long-term poverty alleviation project. 3.3 Including the project into the agenda of all levels of government Soil testing and formula fertilization is a technically very strong public welfare undertaking. It includes policy formulation, fertilizer production, extension services, and distribution and sales. Only when the government strengthens guidance and the departments cooperate with each other, can this work be done effectively. A coffee grinder with a cone-knife grinder places a conical knife disk at the bottom of the machine, and then cooperates with the outer ring knife disk for grinding. The coffee powder produced in this way will be closer to granular, and at the same time, the water absorption path of the coffee particles will become longer, and it will take more time for the inside to contact the water, which will result in the coffee powder being released within the first time. The soluble substances are less, and the concentration will not be too high in a short time.
