What are the common cultivation methods used in vegetable greenhouses?
Vegetable greenhouse cultivation is a growing method with many advantages, as it can effectively reduce various problems that tend to arise during the growing process. For example, droughts, waterlogging and so on; compared with open-field cultivation, it can better ensure the stability and yield of cultivation. Several different cultivation methods have also been derived from vegetable greenhouses, so what exactly are they? Below, the editor brings you the common cultivation methods used in vegetable greenhouses. Let's take a look!
1. Off-season cultivation
Off-season cultivation is the most common growing method in greenhouses. This is because in traditional open-field cultivation, factors such as weather and temperature mean that some vegetables can only be grown in specific seasons. Greenhouses, however, can regulate the growing environment well, allowing most vegetables to be grown in any season. For example, we can grow some autumn vegetables in summer; we only need to take good shading measures and lower the temperature inside the greenhouse. Moreover, using off-season cultivation can meet the market demand for various vegetables in different seasons and improve growing returns.
2. Softening cultivation
Softening cultivation is a cultivation method that has emerged in recent years. It can improve the taste of vegetables and enhance their quality, and once it came onto the market it was welcomed by many people. The main principle of softening cultivation is that after vegetables have grown normally in a greenhouse for a period of time, the light is adjusted so that the environment is set to semi-dark or fully dark, and then humidity is controlled well. Vegetables grown through softening cultivation are tender and delicious, have relatively high nutritional value, and their chlorophyll also decreases somewhat. The most common vegetables for softening cultivation are celery, Chinese chives and so on.
3. Forcing cultivation
Forcing cultivation is actually somewhat similar to off-season cultivation, but the difference is that the main purpose of forcing cultivation is to meet the demand for some vegetables during the off-season. For example, for some vegetables suited to growing in high-temperature environments such as summer, we can use forcing cultivation to grow them in winter and spring. By using the heat-retaining performance of greenhouses to promote the growth of vegetables, this can both meet off-season demand and bring vegetables to market earlier, increasing economic income and expanding one's growing returns. Forcing cultivation is suitable for growing vegetables that are cold-tolerant and like to grow in warm environments.
4. Soilless cultivation
A soilless cultivation method that has emerged in recent years is favored by many growers. Soilless cultivation has low input, relatively high yield, can ensure the quality of vegetables, is almost pollution-free green cultivation, and also reduces environmental pollution. Open-field cultivation cannot do without soil, and soilless cultivation is very suitable for carrying out inside greenhouses. The most common soilless cultivation methods include water culture, nutrient solution cultivation and so on. Soilless cultivation has further promoted the development of the growing industry, improved the quality of vegetables, and the variety of vegetables suitable for growing is also very large.
The above is a brief introduction to the common cultivation methods used in vegetable greenhouses. Compared with open-field cultivation, the various cultivation methods derived from vegetable greenhouses all have more advantages, so everyone can appropriately learn vegetable greenhouse growing techniques!
