with the market competition of agricultural products continue to strengthen the circulation of land scale deepening of agricultural science and technology and improve the level of agricultural machinery automation technology, more and more have an irreplaceable role in modern agriculture, automation technology can not only greatly improve labor productivity and reduce labor intensity, but also improve the quality of work, improve agricultural products market competitiveness. Some of the key technologies to promote the application of agricultural production, to solve the problems in the production of vegetables.  
Automatic driving technology for carrot cultivation  
The beginning of autumn season, in liulihezhen Fangshan District Zhuang village of carrot planting plots, as in previous years, machine drivers of the tractor wildly beating gongs and drums ridging, sowing carrot. Not the same as in previous years, from afar, the carrot ridge shape orderly, each ridge like a straight line in general, very spectacular. Originally, ridging, sowing carrot this year, with the use of the compass agricultural machine hand automatic driving system, the ridge is neat uniform block.  
Beidou agricultural machinery driving technology accurate and efficient  
Compass agricultural automatic driving technology is one of the more mature application of precision agriculture in the field of agricultural technology, automatic driving system is composed of a receiving antenna, a display, a controller, hydraulic valve, angle sensor and base station. The use of automatic driving technology in agricultural land crops that compass between row spacing, spacing at the same time, can accurately work long time without time limit, the busy period can work day and night, avoid light at night because of insufficient operational problems. It can improve the quality and efficiency of the work, reduce duplication of work, save time and reduce the workload of the driver. Can be applied to all aspects of tillage, ridging, sowing, cultivation, plant protection, agricultural harvesting operations.  
In our country, the Beidou agricultural machinery automatic driving system has been applied in some areas, Xinjiang, Heilongjiang and other provinces have been included in the purchase of agricultural machinery automatic driving system catalog. Start the automatic driving system of demonstration and application of agricultural machinery in Beijing city in recent years, has been applied in corn planting, potato ridging, transplanting cabbage field links, made significant demonstration effect.  
Automatic driving technology to grow carrots in one fell swoop  
In recent years, with the development of efficient water-saving agriculture structure adjustment to the requirements, focus on adjusting the agricultural structure, the main crop planting pattern innovation, Beijing City Bureau of agriculture machinery promotion test station identification and implementation of innovative carrot planting mechanization. In the process of planting, ridging, sowing, especially in plant protection, and other aspects of the mid harvest operation requires high quality, need to ensure that the ridge straight, ridge width uniform, in order to reduce the work pressure, pressure late seedling harvesting with ridge ridge, reducing harvest losses brought not straight.  
The use of traditional agricultural planting of carrot artificial driving operation, on the one hand, high requirements for hand machine operation, need to have the ability to control the precision agricultural hand operation route and control line spacing, line the maximum, so as to ensure the ridging, sowing, fertilization, plant protection, irrigation and harvesting of agricultural machinery to play the best the role of providing relatively uniform light, water and fertilizer conditions for crop growth, automatic driving technology is able to solve this problem; on the other hand, in the busy season, time, heavy task, must rush to gather, but only during the day of agricultural operations, hand machine overload operation, operation is difficult to guarantee the quality, the introduction of automatic the driving system can prolong the working time, the night work, improve work efficiency.  
Automatic driving technology can improve the quality of agricultural machinery  
Carrot planting preparatory work is particularly important, standardized pre ridging, sowing directly affects the standardized operation of mid late harvest of plant protection, and thus affects the fruit quality, the harvest yield of carrot. Liulihezhen Fangshan District Zhuang village planted 165 acres of land this year, of which 100 acres of carrot, agricultural application of Beidou automatic driving system for the pre ridging, sowing. The practice shows that the deviation of the line width deviation of the artificial driving is about 8%, while the autopilot error is less than 2%. The use of automatic driving technology can ensure the carrot ridging, sowing in a straight line, laid a good foundation for the standard of all aspects of the entire process of supporting agricultural operations.  
Automatic driving technology can reduce labor intensity  
Through the application of Beidou automatic driving system of agricultural machinery, tractors in advance according to the operation requirement set up working width and other parameters, the use of the Beidou satellite positioning system, through the steering control of the hydraulic system of the tractor, the tractor according to the set route (straight or curved) automatic driving, the driver does not need to operate the steering wheel can easily complete the operation. At the same time to ensure that the agricultural straight line driving, reduce the difficulty of operation. At the same time, to ensure the quality of work in high standard, prolong the time of agricultural operations, in the busy season, can achieve 24 hours of high standard operation, greatly improving the utilization rate of locomotive.
