First, a truck full of vegetables can be planted on a large scale, that is to say, there is no shortage, the demand is large, and money can be made. Second, the planting level is high, and the vegetables grown in Shouguang are really good. This has to be admitted, and it is also profitable for buyers. Third, the development of solar greenhouses in other places is not as good as that in Shouguang, which leads merchants to go further to Shouguang. This forms that when you pass by Shouguang, all you see are sunlight greenhouses, which are dense, because it is more profitable than growing wheat, peanuts and corn.
Why are there fewer and fewer solar greenhouses now? First, out-of-season vegetables are profitable, like mushrooms after rain, and merchants can buy them nearby without going to Shouguang. If the cost can be saved, if so, how do you choose? There are fewer buyers, it is difficult to sell vegetables, and some people are reduced.
Secondly, continuous cropping is a serious obstacle. After the solar greenhouse is completed, it is not easy to change places and it will cost. Moreover, after years of planting, the soil fertility has declined, and a large amount of organic fertilizer has been applied to improve the soil, which makes it difficult to get wet in the critical period, increasing the difficulty of planting, increasing the cost, reducing the profit and reducing the number of growers.
Third, there is a large outflow of talents, which should be focused on. People who have planted greenhouses in Shouguang for several years have mastered various techniques, such as how to plant, how to overcome obstacles of continuous cropping, how to obtain high quality and how to reduce costs. A large number of technicians are transported from Shouguang to all parts of the country, and the planting level in other places has improved, which will have an impact on people who go to Shouguang to pick vegetables and reduce the number of growers.
So there are fewer and fewer agricultural greenhouses in the north.
