What should be paid attention to when growing vegetables in greenhouses?
When growing vegetables in a greenhouse, you need to pay attention to the following points:
1. Temperature control
Temperature has a great influence on the growth of vegetables, too low or too high will affect the growth and development of vegetables. Under normal circumstances, the suitable temperature is 15°C-30°C, and the temperature required by different vegetable types and growth stages is also different. In order to control the temperature in the greenhouse, methods such as ventilation, shading, and water spraying can be used.
2. Light control
Light is necessary for the growth of vegetables, and the time and intensity of light in the greenhouse also affect the growth of vegetables. Generally speaking, vegetables need at least 12 hours of light every day, too strong or too weak will affect the growth and development of vegetables. In the greenhouse, the light intensity and time can be adjusted through sunshade nets, reflective films, etc.
3. Moisture control
Water is necessary for the growth of vegetables, but too much or too little will affect the growth and development of vegetables. In the greenhouse, it is necessary to control the amount and frequency of irrigation to keep the soil moisture moderate and avoid over-drying or over-humidity. At the same time, attention should be paid to clearing stagnant water and weeds in time to avoid affecting the growth of vegetables.
4. Soil fertility
Soil fertility also has a great influence on the growth of vegetables. To maintain sufficient soil fertility, soil fertility can be increased by fertilization, soil replacement and adding organic fertilizers. But be careful not to over-fertilize and cause soil acidification and salinization, which will affect the growth of vegetables.
5. Pest control
The pests and diseases in the greenhouse are relatively easy to breed. Regular inspections are required to detect and deal with the pests and diseases in time. Various methods such as biological control, physical control and chemical control can be used. But we should pay attention to avoid using too much chemical pesticides, which are harmful to vegetables and human body.
6. Reasonable planting
When growing vegetables in greenhouses, it is necessary to plant them reasonably according to their growth habit and growth period, avoiding overcrowding and excessive close planting, which will cause competition between plants and affect growth and development. Reasonable planting methods can make vegetables grow healthier and yield more abundant.
7. Prune and pick regularly
Regular pruning can promote vegetable growth, control plant height and branching, increase ventilation and light, and improve vegetable quality and yield. At the same time, timely picking can stimulate plant growth and ensure the quality and taste of vegetables.
8. Pay attention to management details
Planting vegetables in a greenhouse requires attention to some details, such as cleaning up fallen leaves and weeds in time, keeping the greenhouse clean and tidy; regularly checking the operation of the irrigation and ventilation system to ensure normal operation; timely adjusting the sunshade net and reflective film to ensure light And the appropriate temperature and so on.
9. Reasonable greenhouse design and layout
Reasonable greenhouse design and layout can improve the production efficiency and quality of vegetables. According to the types of vegetables and the planting area, the appropriate greenhouse type and layout should be selected to make full use of the greenhouse space and reduce waste. At the same time, attention should be paid to the setting and operation of the ventilation, sunshade, irrigation and lighting systems of the greenhouse to ensure the needs of vegetable growth.
