A Detailed Explanation of Vegetable Greenhouse Planting Techniques and Management Methods
Greenhouse vegetable planting techniques have now gradually become widespread among us. Greenhouse cultivation can effectively regulate the growing temperature and is easier to manage compared with open-field cultivation. It allows everyone to eat vegetables that are out of season in every season, and it is a planting technique used by many growers. So how exactly should a vegetable greenhouse be operated? Below, the editor brings you the planting techniques for vegetable greenhouses. Let's take a look!
1. Land preparation and fertilization
When using greenhouse cultivation, the requirements for the soil are relatively high. When choosing soil, we must ensure the soil is sufficiently permeable and rich in humus. Then do a good job of land preparation, rake it level, deep-plow the soil once, remove the previous crop residues and weeds, and then apply sufficient base fertilizer. However, because there is a certain difference in temperature inside and outside the greenhouse, the amount of fertilizer applied should be kept moderate to prevent excessive application from damaging the soil structure, and attention should be paid to the amount of nitrogen fertilizer, with phosphorus and potassium fertilizers as the main ones.
2. Variety selection
Although most vegetables can be grown in a vegetable greenhouse, there are also some varieties that are most suitable for cultivation. When choosing varieties to plant, try to choose varieties with strong cold resistance, low light requirements, a preference for growing in humid environments, and a short growth period, such as tomatoes and peppers. Only by ensuring that the vegetables grown in the greenhouse are high-yield and high-quality can we meet market demand and improve our own planting returns. Then build the greenhouse on the soil, with the greenhouse length controlled at about 70-100 m, and then use anti-drip film as the greenhouse surface to facilitate temperature control.
3. Temperature and humidity control
In greenhouse cultivation, because the greenhouse has relatively poor permeability, the temperature and humidity inside the greenhouse tend to rise, which can inhibit vegetable growth. So we must reasonably control the temperature and humidity inside the greenhouse. At noon, in summer, and at other times when the temperature is relatively high, do a good job of ventilation to improve the air quality inside the greenhouse and lower the temperature. Then reasonably control the temperature according to the planted varieties. For some heat-loving vegetables, the temperature should be controlled at around 30°C. Then pay attention to the humidity inside the greenhouse to prevent excessive humidity from hindering vegetable growth. So we must do a good job of ventilation and air exchange, and control the temperature and humidity inside the greenhouse well.
4. Drip irrigation and watering
The rate of water evaporation inside a greenhouse is relatively slower than outside. Especially at night, on cloudy days, and in other low-temperature weather, because the temperature is too low, the air humidity is relatively high, and if there is too much water, the impact on vegetables is very great. So when watering inside the greenhouse, it is best to use the method of drip irrigation under the film for watering. This can not only improve the growing environment inside the greenhouse, but also control humidity and moisture well, promote vegetable growth, and reduce the incidence of pests and diseases.
Of course, when growing in a greenhouse, we should also pay attention to doing a good job of pest and disease control. When eliminating pests, we should reasonably choose insecticides, and we can use insecticides containing substances such as copper and zinc, which not only have a good pest-killing effect but can also promote vegetable growth.
