Why is the old agricultural base in Jiangnan getting worse and worse? What are the countermeasures?

Since 2009, the state began to issue subsidies for agricultural greenhouses, which led to a large number of greenhouses in some areas in order to win subsidies. However, nowadays, with the upsurge receding, some greenhouses are dilapidated and overgrown with weeds, and have completely lost their basic functions.

It is said that if a greenhouse is well done, it can earn 10 thousand yuan a year, recover the cost in three years and double the profit in five years. So what are the reasons for the large number of abandoned greenhouses? How to save these greenhouses?

Some investors with serious losses have little or no knowledge of agriculture themselves, thinking that planting is very simple. They only saw the prospect of growing vegetables in greenhouses, so they flocked to them. It can't be said that vegetables, fruits and edible fungi were all introduced and planted. As a result, they naturally suffered serious losses and finally gave up.

Personnel faults operate greenhouses all the year round, and the prevalence of rheumatism is high in high temperature and high humidity environment, which makes many young people stay away from it. It also led to some farmers over 45 years old being forced to give up planting for physical reasons, which led to the abandonment of greenhouses.

It is difficult to loosen the soil completely because of the poor illumination in the soil hardening greenhouse. With the growth of planting time, due to the increase of fertilizer intake and soil hardening, many growers gradually gave up greenhouses after operating them for several years.

Farmers who grow special-purpose rice sometimes choose to raise seedlings in greenhouses. Once the seedlings are raised, the greenhouse will naturally become idle, but this kind of rice will not be completely abandoned, but will continue to be used next year.

How to save abandoned greenhouses? In view of the problem of long-term idleness or even abandonment of greenhouses, relevant experts gave the following suggestions:

1, planting out-of-season vegetables to get high profits. Local vegetable farmers in Shouguang, Shandong Province use winter-warm solar greenhouse to grow out-of-season vegetables, and a large number of vegetables are listed around the Spring Festival in a year. Winter is the highest price of vegetables in a year, and the profit from listing and supply is considerable.

2. Positioning famous, excellent and high-grade vegetables to be planted around big cities such as Beijing, Shanghai, Qingdao and Hangzhou. Due to the high consumption level and many high-end hotels, it is possible to develop and cultivate famous, excellent and special vegetable varieties. To meet the higher market demand, the economic benefits are very considerable.

3. Rational planting to improve soil quality Through scientific and reasonable fertilization, planned rotation, moderate deep ploughing and timely intertillage, soil quality can be improved, farmland pollution can be reduced, soil hardening can be avoided, and the life of greenhouse can be prolonged.

Integrate the greenhouse industry, cultivate organic vegetables with greenhouse facilities, and directly connect the products with large shopping malls and hotels to form an integrated operation of production, supply and marketing, or combine ecological vegetable planting with tourism for consumers to visit and pick.

In recent years, the state has invested a lot of money to subsidize the development of facility agriculture. Although the state subsidizes a lot, if the facilities and greenhouses can't really be used, no matter how powerful the subsidies are, it will be futile. The vast number of farmers still have to think in many ways and make plans before acting.
