Analysis of the Latest Planting Prospects for Greenhouse Vegetables
Greenhouse vegetable cultivation is a relatively common technique with good insulation performance, and it is deeply loved by people, because off-season vegetables can be eaten at any time. Now let us take a look at just how promising the prospects for greenhouse vegetable cultivation really are!
The Planting Prospects of Greenhouse Vegetables
The advantage of greenhouse vegetables lies in their off-season nature. In winter, for example, pepper plants generally freeze to death, but they can be grown in a greenhouse, and at that time there is market demand. Nowadays greenhouse vegetables are gradually becoming widespread, and market demand is gradually increasing, so there are relatively good market prospects.
How Can the Risks of Greenhouse Vegetable Cultivation Be Avoided?
1. Market awareness: Vegetables differ from other products in that they are relatively constrained by natural conditions and are not easy to store, so once supply exceeds demand and a backlog occurs, it will cause huge losses. Vegetable growers should pay attention to collecting supply-and-demand information and price information fed back from the market. In terms of vegetable varieties, quantities and planting times, they should be market-oriented, grasp market trends, analyse market potential, and carry out planning and adjustments in a timely manner to produce products that are well suited to demand.
2. Scientific and technological awareness: The cultivation and management of greenhouse vegetables is a complex and meticulous technical task, such as maintaining suitable light, temperature and humidity in the greenhouse, fertilising scientifically, and carrying out harvesting, transport and storage reasonably. Among these, because greenhouse vegetables are very prone to pests and diseases, doing a good job of pest and disease control is the key to production. It can be said that the entire process of greenhouse vegetable production is inseparable from scientific and technological knowledge. Vegetable growers should be clear about the idea of “growing vegetables with science and technology” and raise their own scientific and technological level in all respects. They should actively introduce and apply new technologies to raise production levels.
3. Quality awareness: People's dietary consumption today has gradually shifted from emphasising quantity to emphasising quality, and this is especially true in vegetable consumption. Green and environmentally friendly vegetables are increasingly welcomed by consumers. Therefore, vegetable growers should change traditional, backward planting methods and management models, be careful and calculate closely in the application of agricultural inputs such as pesticides, chemical fertilisers and growth agents, apply them reasonably, and strive to produce high-quality green vegetable products that are non-toxic, harmless and pollution-free. This not only conforms to people's consumption trends, but also increases the competitiveness of products and helps to further open up markets.
4. Awareness of seeking novelty and speciality: There are many kinds of greenhouse vegetables. In addition to growing ordinary off-season vegetables, vegetable growers should pay attention to catering to consumers' desire for novelty and speciality, and appropriately grow some special and rare vegetables. Such vegetables are generally welcomed and usually fetch higher prices, making this a market with great development potential.
5. Awareness of scale: Only when greenhouse vegetable cultivation reaches a certain scale can considerable economic benefits be obtained. Some vegetable growers who are mature in technology and sales can, through investigation and analysis, rely on existing advantages to open up new markets and expand production scale, thereby turning individual advantages into local advantages and enabling more people to get rich. By all means, do not be satisfied with the status quo and hesitate to move forward.
Points to Note in Greenhouse Vegetable Cultivation
1. Choose a good greenhouse site and improve the supporting water system: Before determining the greenhouse site, investigate whether the site has sufficient water sources and whether the water sources are polluted. Once there is sufficient water, ditches and canals must be dug well to facilitate water diversion and drainage. Where conditions permit, each greenhouse should be equipped with a water supply tap. Those with higher standards should also be equipped with sprinkler irrigation facilities.
2. Fertilise in a balanced way to promote steady growth of vegetables: (1) Apply fully decomposed organic farmyard manure all year round. (2) Apply refined organic fertiliser and high-energy organic fertiliser, such as Yemeifeng and Guomeifeng. (3) Change the partial application of nitrogen and phosphorus to reducing nitrogen, stabilising phosphorus, increasing potassium, and applying trace element fertilisers in combination. (4) Apply fertiliser in divided, appropriate amounts. (5) Once fertiliser damage occurs, spray a variety of active liquid fertilisers to alleviate the harm.
3. Use pesticides scientifically to ensure vegetable safety: (1) For minor pesticide damage, the method of strengthening fertiliser and water management can be used to restore the normal growth functions of vegetables. (2) Choose the right targeted pesticide; herbicides in particular must be applied with caution. (3) Keep a firm grip on the dosage and concentration of pesticides, and at the same time avoid repeatedly using a single pesticide. (4) By all means, do not mix pesticides arbitrarily. (5) Avoid high temperatures when applying pesticides. (6) Equipment used to apply herbicides must be cleaned thoroughly before being used again.
4. Carry out crop rotation and change stubble to adjust the vegetable cultivation environment: (1) For vegetables prone to disease, such as eggplant, tomato and cucurbits, change to planting other vegetable varieties in different years or different seasons. (2) Greenhouses prone to continuous cropping obstacles should be given increased organic fertiliser to improve the soil. (3) Use soil continuous cropping agents to inhibit pathogens. (4) For soil deficient in elements, promptly supplement the lacking nutrients.
