The land preparation task of 200 million mu of agricultural machinery deep loosening was overfulfilled in 2015.

Since the beginning of this year, departments in charge of agricultural mechanization at all levels have resolutely implemented the deployment of "increasing subsoiling land by 13.33 million hectares (200 million mu)" in the Government work report. Agricultural machinery subsoiling land preparation as an important technical measure to tap the potential of grain production, scientific planning, meticulous organization, and strong promotion. By November 30, the country had completed 166.46 million mu of deep loosening in autumn, plus 36.98 million mu in spring and summer, and completed a total of 203 million mu of land preparation area in the whole year, exceeding the task of 200 million mu of agricultural machinery. At present, the land preparation work of deep loosening of agricultural machinery in most provinces (regions) has been completed, and the remaining southern provinces (regions) have entered the final stage and will end in late December.

In order to ensure the complete completion of the deep loosening task, the Ministry of Agriculture assigned 200 million mu of subsoiling tasks to the relevant provinces at the beginning of the year, and established a monthly progress report and assessment system, regularly reported to the State Council the development of deep loosening of agricultural machinery and informed the provinces, and constantly enhanced the sense of responsibility of all localities in implementing the annual targets and tasks. Before the great rush of the "three Autumn", the Ministry of Agriculture held a special on-the-spot meeting on the land preparation work of deep loosening of agricultural machinery to carry out mobilization and deployment; from late September to early November, the Ministry of Agriculture sent a number of supervision teams. they went to the northeast, north China, northwest, Huang-Huai-Hai and other key areas to carry out special inspections. All provinces and autonomous regions actively respond to the deployment of the State Council, strengthen organizational leadership, refine work plans, and implement goals and responsibilities. Hebei Province implements the county magistrate responsibility system for deep loosening operation, which provides a strong organizational guarantee for promoting the implementation of the goal.

In order to strengthen the support of agricultural machinery and equipment for deep loosening land preparation, the Ministry of Agriculture requires all localities to give priority to meeting the needs of farmers for purchasing high-power tractors, deep loosening machines, combined land preparation machines and other operating equipment in the implementation of the machine purchase subsidy policy, and appropriately raised the subsidy standard for deep loosening machines. Take the commonly used 4-to-5 shovel deep loosening machine as an example, the subsidy for each machine is 3000 yuan, accounting for about 30% of the market price. By the end of November, the subsidy funds for tractors and subsoiling machines this year reached 6.7 billion yuan, with 290000 new tractors and 9512 subsoiling machines (sets) added. The number of tractors and subsoiling machines with more than 80 horsepower in the country exceeded 750000 and 234000 respectively.

In order to further arouse farmers' enthusiasm for deep loosening and land preparation, the Ministry of Finance and the Ministry of Agriculture have expanded the pilot provinces of subsidies for deep loosening land preparation operations from Northeast and North China last year to all suitable areas such as Northwest, East and Southwest. The specific subsidy standards are independently determined by the provinces according to local operating patterns, costs, farmers' wishes and other factors, ranging from 15 yuan to 40 yuan per mu. According to preliminary statistics, this year, the provinces have allocated 1.95 billion yuan for subsoiling operations (including 1.42 billion yuan from the central government), with a proposed subsidy area of 79 million mu. At present, the subsidy pilot areas have adopted the method of "working first and then subsidizing, first publicizing and then cashing in", and have successively issued subsidies for deep loosening of agricultural machinery to farmers and robots.

In order to strengthen the supervision of agricultural machinery subsoiling operation quality and ensure that the operation subsidy standards are in place, the Ministry of Agriculture has actively promoted the use of satellite positioning, Internet of things and other information means to supervise and manage subsoiling land preparation. Heilongjiang, Anhui, Shandong and other provinces vigorously guide the installation of deep loosening testers to realize remote monitoring and real-time statistics of agricultural machinery subsoiling operation process, working area, and working quality, which greatly improves the efficiency of supervision and effectively avoids questions such as misrepresentation of area and subsidy.

According to reports, deep loosening operation can effectively break the bottom of the plough and increase the capacity of soil water storage and soil moisture conservation and crop yield. The 4-year comparative yield measurement in Suihua City, Heilongjiang Province shows that the average increase of corn per mu is about 125 kg. Monitoring data in Hebei Province show that after deep loosening, the water storage capacity of land increases by about 15%, and the average increase of wheat and corn is about 10%.
