Avoid the normal cultivation season and market supply period of vegetable varieties, and use special cultivation techniques to grow vegetables to improve efficiency. Such as; In autumn, shade-tolerant vegetables such as Chinese cabbage, cauliflower and radish are covered with sunshade nets to cool down; Water spinach, eggplant and melons cultivated in spring and summer; Off-season vegetables planted in greenhouses in winter.
2. Softening cultivation
That is to say, when vegetables grow to a certain extent, set a semi-dark or dark environment and maintain appropriate temperature and humidity, so that vegetables and plants can grow in rare dark conditions. The vegetables cultivated by this method have less chlorophyll, soft stems and leaves and unique flavor. For example, the production of leeks, garlic and celery can be softened in the cultivation technology of sprouts!
3. Delayed culture
That is, take artificial control measures to extend the growth and supply time of vegetables. For example, all kinds of vegetables cultivated in autumn are covered before the first frost to keep warm and cold, and prolong the growth period. Vegetables suitable for this kind of planting are solanaceous fruits, melons, green leafy vegetables and cabbage.
4. Promote cultivation
From winter to early spring, vegetables are cultivated in solar greenhouses, greenhouses and small arch sheds to meet the market demand in the off-season. All kinds of vegetables that like temperature and cold can be popularized and planted.
5. Summer cultivation
Over-summer cultivation is to artificially create an environment suitable for vegetable growth in summer, and use shading and cooling to make vegetables grow safely over summer. Vegetables such as tomatoes, leeks and celery grow in summer.
That is, protected facilities nutrient solution cultivation. Commonly used methods include hydroponics, nutrient solution membrane and so on. Soilless culture has the advantages of high yield, good quality, fast production speed, no pollution and low production cost. Widely used in all kinds of vegetables, which is the development direction of production.
