Using greenhouses to grow strawberries has the advantages of small investment, quick results, low risk, and easy to obtain high yields. It has become the main cultivation method of strawberry. Today I will introduce to you the greenhouse strawberry growing technology and management methods.
Greenhouse strawberry planting technology
- Choose good varieties
Greenhouse strawberry have a long growth period. Be sure to choose ones with good cold resistance and resistance to low temperatures and low light. It also has strong disease resistance, easy fruit setting and high yield. And good quality strawberry varieties. Such as Toyoka, Hongyan, Zhangji, Tochiotome, etc. It is easier to obtain high yields by planting these varieties.
- Cultivate strong seedlings
Choose healthy, disease- and insect-free seedlings for planting. Planting in autumn has a high survival rate and a short seedling recovery period. And the results come early in the second year.
- Preparing and fertilizing the land
Strawberries have shallow root systems and strong fertilizer requirements. Therefore, it is important to choose soil that has strong water and fertilizer retention capabilities and is rich in organic matter.
- Colonization management
The planting time is based on strawberry variety characteristics, climatic conditions and other factors. Generally, the northern region is suitable for planting in early to mid-September. The planting density is about 7,000 plants per acre, and the spacing between plants is generally 20 cm × 30 cm. during the colonization process. Pay attention to placing the arched back of the strawberry seedlings toward the outside of the ridge. And determine the depth of the plant in accordance with the principle of “not burying the heart deeply, not exposing the roots shallowly”.
- Temperature and humidity management
During the growth period of strawberries, careful temperature and humidity management. Maintain the temperature inside the shed by covering it with mulch and adding straw curtains. At the same time, pay attention to ventilation. Especially at noon when the temperature is higher. The vents on both sides of the greenhouse need to reduce the temperature inside the greenhouse. In terms of humidity, pay attention to keeping the soil moist and avoid being too dry or too wet.
- Cultivating and weeding
During the growth of strawberries, cultivating and weeding keep the soil loose and eliminate weed growth. Generally, the appropriate cultivating depth is 5-10 cm, and should not be too deep to avoid damaging the strawberry root system. When it comes to weeding, manual weeding or selective herbicides can be for removal.
- Pest and disease control
Strawberries are susceptible to pests and diseases, so be sure to prevent them during planting. Common strawberry diseases and insect pests include anthracnose, powdery mildew, gray mold, etc. Prevention can be carried out by measures such as strengthening ventilation and reducing humidity. Once pests and diseases are discovered, corresponding measures need to be taken promptly for treatment. Such as using chemical spraying, etc.
- Plant adjustment
During the growth of strawberries, plant adjustments need to be made to promote improved fruit quality and increased yield. Generally, it is necessary to remove leaves, remove stolons and other treatments. To reduce nutrient consumption and promote ventilation and light transmission. At the same time, excess side buds and flower buds need to remove in time to avoid affecting the flowering and fruiting of the main buds. during the fruit ripening stage. Some old leaves, diseased leaves and residual leaves can be appropriately cut off as needed. to promote fruit development and ripening.
