Due to the large latitude, there are some differences in harvest time of wheat, rice and other crops in China. Even in the same province, the differences in harvest time caused by differences in ecological conditions can reach a week or even more than a month, making it possible to allocate agricultural machinery.

Compared with the operation in the same area, the cross region operation can extend the operation time by 3 - 4 times, greatly improve the use efficiency of agricultural machinery, greatly shorten the investment payback period of purchasing machinery, and greatly improve the enthusiasm of agricultural machinery operators to provide services.

Compared with manual harvesting, machinery can replace a large number of labor force and greatly improve labor productivity, which is welcomed by farmers.

In the current practical production operation, the operation information of agricultural machinery mainly depends on the experience of the owner to determine the operation area and place subjectively. There are many factors affecting the decision-making of the owner, including time, place, road condition, model and quantity, operation capacity, operation price, operation area, idle time, social benefits, etc. Due to the lack of scientific basis, the subjective decision-making scheme of agricultural machinery allocation lacks of scientific nature, which makes the service cost of agricultural machinery increase and the income is difficult to be maximized. Among the many influencing factors, how to choose the operation location and operation path to get the most benefit is not only a problem that the owner cannot draw a conclusion intuitively, but also a very difficult decision-making problem [2].

In the busy season, when the extreme weather is about to happen, the relevant government departments will organize to complete the task of harvesting and planting in a specific time. Most of the government departments are also based on subjective experience [3]. How to allocate agricultural machinery scientifically in order to complete the task better is a difficult but necessary problem for the management department.

With the development of cooperative economy, there are more and more agricultural machinery cooperators. They mainly rely on subjective experience to allocate agricultural machinery through manual distribution, voice communication and other traditional methods. The agricultural machinery cooperator contacts the agricultural machinery owner through mobile phone to know the status of agricultural machinery and the completion of farmland tasks in real time. At the same time, contact with the grower to understand the information of the order to be operated, and according to the actual situation and experience, select and dispatch the idle agricultural machinery closest to the operation point to transfer to another operation point for harvesting service [4]. However, this traditional scheduling method is prone to the problems of job information lag, poor timeliness and low efficiency.

With the progress of science and technology, the continuous progress of navigation system, satellite positioning and other technologies, in order to adapt to the development of new technologies, some agricultural machinery owners use wireless communication technology to establish agricultural machinery monitoring system to achieve real-time monitoring of harvester operation position and status in cross regional operation, but in terms of scheduling decision-making, it still depends on the subjective allocation and decision-making of dispatchers, without the farmland task and scientific and systematic planning of harvester resources and various influencing factors [5].

In the region, due to the unreasonable sequence of plot operation, if agricultural machinery in the process of changing farmland plot has many detours, it will reduce the working efficiency, cause waste of time, oil, human resources and other resources, and increase the operating cost. Outside the region and in the process of cross regional deployment, there is a lack of overall scientific system planning, unclear understanding of the transfer path, road, weather and operation site, blind based on the needs of the owner or subjective judgment, which is easy to lead to the coordination between the supply and demand of machines and tools and waste of resources. On the one hand, idle agricultural machinery cannot arrive at the operation site on time, delaying agricultural time. On the other hand, working agricultural machinery rushed to reduce work efficiency [6].

In the allocation of agricultural machinery, is the greater the horsepower of agricultural machinery, the best benefit? The allocation of agricultural machinery should be based on the main terrain characteristics, soil type, plot area, ridge length, etc. of the operation site, and the appropriate model and quantity of harvester should be allocated. The suitability of harvester and plot will have a great impact. It is not necessarily the best benefit to select high-power harvester for small plot.

To a certain extent, the difficulty in the allocation of agricultural machinery stems from small-scale operation. The low efficiency of agricultural production and too small cultivated area directly affect the demand tendency of agricultural machinery market for agricultural machinery scale.

Agricultural machinery is often accompanied by overload operation and lack of inspection and maintenance during the busy period. The long-term non intermittent operation of agricultural machinery is the main cause of a variety of agricultural machinery failures. Due to the lack of rest and maintenance, the long-term work of agricultural machinery in a bad state cannot only improve the efficiency of labor production, but also seriously affect the production progress due to a variety of failure problems [7]. Therefore, in order to improve the efficiency of agricultural machinery, it is necessary to adopt intermittent operation or rotation operation to ensure the standardized use of agricultural machinery.

Encourage advanced agricultural machinery to carry out service operations in the region. Farmers complete high-quality agricultural production requirements by leasing advanced agricultural machinery, which not only avoids idle problems caused by excessive purchase of agricultural machinery, but also completes corresponding agricultural production tasks. The owners of advanced agricultural machinery and equipment can also obtain good economic income through service operations.

Encouraging the cross regional operation of advanced agricultural machinery and the compliance of agricultural production with the seasons leads to the idle of agricultural machinery resources. Through the cooperation between regions, the operation time of agricultural machinery can be extended in a large range to ensure the efficient utilization of advanced agricultural machinery and equipment [8].

The agricultural machinery management department should effectively ensure the utilization rate of agricultural machinery resources through scientific management. Abandon the extensive management mode in the past, carry out refined management on agricultural machinery and equipment, do a good job in the registration and statistics of advanced agricultural machinery and equipment, and clarify the operation characteristics and application scope of agricultural machinery and equipment. In order to ensure the steady progress of the utilization of agricultural machinery resources, we should formulate a scientific and advanced allocation system of agricultural machinery resources and a reasonable management and allocation plan based on the characteristics of agricultural machinery. Do a good job in communication and coordination between agricultural machinery to be deployed and the objects to be served to ensure the reliable implementation of agricultural machinery resource allocation and service operations.

According to the actual situation of agricultural mechanization production, the quantity of advanced agricultural machinery is still insufficient. The technical backwardness of small agricultural machinery will seriously affect the efficiency of agricultural production, and is not conducive to the popularization of large-scale advanced agricultural machinery. Agricultural Machinery Extension departments should pay attention to the promotion of advanced agricultural machinery and equipment, and promote the improvement of the retention of advanced agricultural machinery [9].

Through the optimization of agricultural production and management mode to reduce the use of small and backward agricultural machinery, while reducing the number of agricultural machinery, optimize the quality and scientific and technological content of agricultural machinery. At the same time, we will promote the transfer of land, create convenient conditions for the work of high-quality agricultural machinery, and achieve the goal of agricultural production through a small number of high-quality agricultural machinery.

At present, the process of Agricultural Mechanization in China reflects the characteristics different from that in developed countries, which is the imbalance of the level of agricultural mechanization. Due to the differences of geographical and climatic conditions in China, the process of agricultural mechanization will reflect the development characteristics of different regions, different production conditions and different economic development levels. In order to guide the efficient harvesting of agricultural crops, standardize the management of agricultural machinery, so as to accelerate the further development of China’s agriculture and realize the rapid development of agricultural economy, this paper studies the establishment and practical application of the principle of cross region intelligent scheduling of agricultural machinery.
