China is the largest vegetable producer and consumer, and the growth rate of vegetable cultivatio is higher than the world average. According to the National Bureau of Statistics, In 2016, the national vegetable planting area was about 22 million hectares. Among them, greenhouse vegetables are 5 million h㎡,
Vegetable production is about 800 million tons, The planting area and output account for more than 40% and 50% of the world's total, respectively.
China's vegetable mechanization is currently in the initial stage, with a comprehensive mechanization level of less than 30%. Plain open field vegetables benefited from the development foundation of field machinery in the early stage in fertilization, soil preparation, sowing, plant protection and irrigation etc., and the degree of mechanization was relatively high.
Due to the limited operating environment of facility vegetables, large-scale agricultural machinery generally has the problems of "difficult to walk, difficult to enter, difficult to cultivate on the side, difficult to drop the head, and difficult to achieve high efficiency", and only a few small agricultural machinery can carry out operations.
As the leading industry of high-efficiency agriculture, facility vegetables are an important symbol of modern agriculture. The planting area accounts for 1/4 of the total area of vegetables, and it is increasing year by year. There is an urgent need for mechanization. Therefore, flexible and practical small agricultural machinery has broad application prospects in the production of facility vegetables.
