1. Lack of awareness.
"Precision agriculture" is first of all a new concept based on information and knowledge of scientific management of agricultural resources, therefore, in a sense, the technical ideas of precision agriculture technology can be popularized and applied in any region, different agricultural production conditions, and different crop production. Some researchers, due to the constraints of their research fields, do not know much about the development status and trend of international precision agriculture technology, and often have some wrong understanding of precision agriculture technology ideas.
2. Socio-economic issues.
There are obvious differences in the natural conditions and socio-economic conditions in various parts of China, and there is a large gap in the level of agricultural production.
The degree of mechanization is not high. The scale of cultivation is small, the soil quality is different, the land is scattered, and the practice of precision agriculture technology is obviously a constraint. How to develop large-scale operation and how to promote the assembly mode of precision agriculture technology suitable for China's national conditions need to be studied.
In addition, the implementation of precision agriculture technology requires some necessary software and hardware systems, which requires basic capital investment, the return period and economic benefits of these investments.
Socio-economic issues such as assessment and even environmental benefit assessment are yet to be studied.
3. Engineering and technical problems.
Several large agricultural machinery manufacturing enterprises in the world have successively produced harvesters with GPS positioning systems and yield sensors.
And the corresponding information processing system has been developed. In China, the experimental demonstration of precision agriculture technology has begun, but mainly by the introduction of technical equipment. Obviously, this method cannot be popularized and used in the vast areas of our country.
At present, some key technologies to support the practice of precision agriculture in China have not been solved, such as the rapid acquisition technology of soil fertility information positioning, the technology of grain flow monitoring and the generation of spatial distribution information of crop yield in harvesting machinery, and the technology of intelligent variable mechanical control. Therefore, to promote precision agriculture technology in China, it is necessary to vigorously carry out scientific research on key technologies of precision agriculture and train relevant talents.

Refined agriculture needs to rely on traditional agriculture to strengthen scientific and technological investment and other methods to operate.
Method: Refined agriculture is a comprehensive agricultural system, which relies on traditional agricultural technology and scientific and technological progress, aims at producing high-quality, high-tech and high-value-added agricultural products, and takes characteristic layout, standardized production and industrialized operation as the main starting point, so as to achieve a high-quality, high-efficiency and high-level agricultural production process.
Its foundation is high investment and high technology, its core is high standardization and high quality, it is characterized by precision and special, and its ultimate goal is high competitiveness, high quality and high returns.
In terms of production mode, intensive cultivation is required to obtain maximum output benefits with the least input and resource consumption; In terms of production form, high quality, high added value and high commodity rate are required to meet the quality requirements of the market for agricultural products and their processed products; In the production process, modern science and technology are required, and all aspects of production, processing, packaging, and circulation are standardized.
Refined agriculture is an important form of modern agriculture, and the process of agricultural refinement is the process of optimizing the allocation of various production factors in agriculture, the process of changing the mode of agricultural growth, and the process of improving the quality and efficiency of agricultural management.
To obtain the maximum output benefit with the least input and resource consumption, it is required to make agricultural products of high quality, high added value and high commodity rate, enhance the international competitiveness of agricultural products, and also benefit farmers.

1. The investment and promotion of agricultural scientific research forces meet the requirements of the development of "refined agriculture" for new technologies and new varieties.
2. A series of services for pre-production, production and post-production of agricultural production.
3. Establish a marketing system integrating production, supply and marketing.
1) Grading standards for agricultural food, and improving the modernization level of agricultural food transportation and marketing.
2) Establish a new production and marketing system.
3) Agricultural product distribution companies to achieve the decentralization of investment subjects.
There are many ways to improve your popularity and self-confidence, first of all, you have to change from your heart, care more about your friends, cultivate your temperament, learn to speak is the most important, you should consider the feelings of others when you speak, don't be too strong in tone, self-confidence is the most important, ask high self-confidence from discovering your own advantages, but don't be arrogant, self-righteous, optimistic about the world too much, in short, the mentality changes everything, so that others' views of you will also become better, it is useless to say more, see how you grasp it, there is a problem Li Ge, solve it for you.
