What are the properties of the greenhouse used for growing vegetables?
Greenhouses play an important role in vegetable cultivation, and their various properties provide good conditions for vegetable growth. The following is a detailed analysis of the greenhouse properties that play a key role in promoting vegetable growth.
1. Temperature control: For many vegetables, the right temperature is the basis for growth. Through the special structure and materials, the greenhouse can effectively maintain the temperature inside the shed and avoid the influence of extreme temperature outside. In the cold season, greenhouses can provide enough heat to ensure that vegetables are not damaged by freezing. In the hot season, greenhouses can effectively cool down and prevent vegetables from overheating. This temperature stability provides a better growing environment for vegetables.
2. Light management: Light is a key factor in plant photosynthesis. Vegetable greenhouse are usually made of transparent materials, such as glass or plastic film, which allow in a lot of sunlight. At the same time, the greenhouse is also equipped with external shading and internal shading system, according to the strength of the sun and the needs of vegetables to adjust, to prevent strong light to cause damage to vegetables. This fine light regulation ensures that the vegetables get enough light without excessive light.
3. Humidity control: Humidity is also important for the growth of vegetables. Through the ventilation system, irrigation system and soil moisture regulation system, the greenhouse can maintain the humidity in the shed within the appropriate range. In a dry environment, vegetable greenhouse can increase humidity and prevent excessive water loss of vegetables; In a humid environment, greenhouses can reduce humidity and prevent vegetable diseases.
4. Soil improvement: Soil is the basis of vegetable growth. Vegetable greenhouse improve soil structure and fertility through scientific soil management techniques, such as soil disinfection, the addition of organic fertilizers and crop rotation systems. This not only facilitates the growth of vegetable roots, but also improves the resistance of the soil to disease and reduces the use of fertilizers and pesticides.
5. Pest control: Pests and diseases are the enemy of vegetable growth. Through the closed environment and advanced monitoring system, the greenhouse can detect the occurrence of diseases and pests in time. On this basis, vegetable greenhouse adopt biological control, physical control and chemical control and other means to effectively control the spread and spread of diseases and pests. This greatly reduces the use of pesticides and ensures the safety of vegetables.
6. Water-saving irrigation: In vegetable greenhouse, water-saving irrigation methods such as drip irrigation and sprinkler irrigation are usually used. These technologies can supply water according to the needs of vegetables and the moisture of the soil, which not only saves water resources, but also ensures that vegetables get the right amount of water.
