The latest planting prospect of vegetables in greenhouse

Greenhouse vegetable cultivation is a relatively common technology, which has good heat preservation performance and is deeply loved by people, because out-of-season vegetables can be eaten at any time. Let's take a look at the planting prospects of greenhouse vegetables.

Planting prospect of vegetables in greenhouse

The advantage of greenhouse vegetables lies in anti-seasonality, such as winter, the general chili trees are frozen to death, but the greenhouse can be planted, then there is market demand. Nowadays, greenhouse vegetables are becoming more and more popular, and the market demand is also increasing, which has a good market prospect.

How to avoid the risk of growing vegetables in greenhouse?

1. Market consciousness: different from other products, vegetables are not easy to be stored because they are limited by natural conditions, so once the supply exceeds demand, there will be a backlog, which will cause huge losses. Vegetable farmers should pay attention to collecting market feedback supply and demand information and price information, take the variety, quantity and planting time of vegetables as the guidance, grasp the market trend, analyze the market potential, plan and adjust in time, and produce marketable products.

2. Scientific and technological consciousness: the planting and management of vegetables in greenhouse is a complex and fine technical work, such as keeping suitable light, temperature and humidity in greenhouse, fertilizing scientifically, harvesting, transportation, storage and so on. Among them, as greenhouse vegetables are prone to diseases and insect pests, so the prevention and control of diseases and insect pests is the key to production. It can be said that the whole process of vegetable production in greenhouse is inseparable from scientific and technological knowledge. Vegetable farmers should make clear the idea of "growing vegetables through science and technology" and improve their scientific and technological level in an all-round way. Actively introduce and apply new technologies to improve production level.

3. Quality consciousness: nowadays, people's food consumption has gradually changed from quantity to quality, especially in vegetable consumption. Green and environment-friendly vegetables are more and more popular among consumers. Therefore, vegetable farmers should change the traditional backward planting and management mode, carefully calculate and reasonably apply agricultural products such as pesticides, chemical fertilizers and production elements, and strive to produce high-quality green vegetable products that are non-toxic, harmless and pollution-free. It not only conforms to the consumption trend of people, but also increases the competitiveness of products, but also helps to further open up the market.

4. Consciousness of seeking new and special vegetables: there are many kinds of vegetables in the greenhouse. In addition to planting ordinary out-of-season vegetables, vegetable farmers should pay attention to the psychology of consumers seeking new and special vegetables, and properly plant some special and rare vegetables, which are generally welcomed. And the general price is high, it is a market with great development potential.

5. Scale consciousness: only when growing vegetables in greenhouse forms a certain scale, can considerable economic benefits be achieved. Some vegetable farmers who are mature in technology and sales can, through investigation and analysis, rely on their existing advantages, open up new markets, expand the scale of production, and then turn their personal advantages into local advantages, so that more people can embark on the road to prosperity. Do not be satisfied with the status quo and hold back.

Matters needing attention in planting vegetables in greenhouse

1. It is necessary to select the shed site and improve the matching of the water system: before determining the greenhouse, it is necessary to check whether the shed site has sufficient water source and whether the water source has been polluted. With sufficient water sources, ditches and canals must be opened to facilitate water diversion and drainage. Where there are conditions, a water supply faucet should be installed in each greenhouse. Those with high standards should also be equipped with sprinkler irrigation facilities.

2. Balanced fertilization should be applied to promote the steady growth of vegetables: ① should apply fully mature organic manure all the year round. ② should apply refined organic fertilizer and high-energy organic fertilizer, such as Ye Meifeng, Guo Meifeng and so on. ③ should change the partial application of nitrogen and phosphorus to reducing nitrogen, stabilizing phosphorus, increasing potassium, and applying micro-fertilizer. ④ should apply appropriate amount of fertilizer in different stages. When fertilizer damage occurs in ⑤, it is necessary to spray a variety of active liquid fertilizers to alleviate the damage.

3. It is necessary to use drugs scientifically to ensure the safety of vegetables: if there is a slight drug damage to ①, the method of strengthening fertilizer and water management can be used to restore the normal reproductive function of vegetables. ② should choose the right pesticides, especially herbicides should be used cautiously. ③ controls the dose and concentration of pesticides and avoids the repeated use of a pesticide. ④ must not mix pesticides at will. ⑤ application should avoid high temperature. ⑥ instruments that have been used with herbicides must be cleaned before they can be used again.

4. Change crop rotation and adjust vegetable cultivation environment: ① eggplant, tomato and melon are susceptible to disease, and other vegetable varieties should be changed year by year or season by season. The greenhouse where ② is prone to continuous obstacles should apply more organic fertilizer to improve the soil. ③ chooses soil heavy stubble agent to restrain bacteria. ④ replenishes the deficient nutrients in time for nutrient-deficient soils.
