Design and Experimental Research on Precision Fertilization Device for Vegetables
摘要
Abstract
In order to solve the fertility requirements of soil base fertilizer and the problem of uneven fertilization before vegetable planting,a precision fertilization device was designed.In this paper,the working principle of the fertilizer ap-plicator is introduced,and the static simulation analysis and modal analysis are carried out on the frame of the precision fertilization device,and the part with greater stress is improved,so as to ensure the stability of the vegetable precision fertilization device.The results show that the main and secondary factors affecting the coefficient of variation are spraying height,sprinkler spacing,and total sprinkler flow,and the optimal process combination is A1B2C2,that is,the spraying height is 0.5 m,the sprinkler spacing is 0.4 m,and the total nozzle flow rate is 2.0 L/min.The device can reach the fertility requirements of the base fertilizer,and can realize the quantitative discharge of nitrogen,phosphorus and potas-sium fertilizers and water,which improves the precision effect of the fertilization device,and is of great significance to the development of precision fertilization technology and fertilization device.关键词
