The planting technology of strawberry in greenhouse is explained in detail! It is critical to control the temperature in the shed.

As a common fruit in autumn and winter, strawberries are loved by many people every year. Different varieties of strawberries are cultivated by farmers in many areas of our country. As a fruit of Rosaceae, it tastes sweet and juicy, and has high nutritional value. So do you know the cultivation of strawberries in the greenhouse?

Cultivation of strawberries in greenhouse

Growing strawberries in greenhouses is already common, with a short cycle and early fruit, which is easier than the old-fashioned method. The specific methods are as follows:

1. Soil

The soil in the greenhouse can be directly disinfected by the photosynthesis of the sun, and then applied a layer of organic fertilizer, sealed with a thin film for a week, can effectively kill the pests in the soil. Wait until a week later to uncover the film and then apply cake fertilizer and other compound fertilizers to loosen the soil and do the work of land preparation. This step is the same as our common strawberries, loosening the soil, ploughing and filling. It is enough to ridge the line width and spacing that have been budgeted in advance.

Note: the width of the face of strawberries planted in the greenhouse is 50 cm, and the width of the bottom is 60 cm. The width of the bottom of the ditch can be reduced to about 35 cm.

2. Colonization

The time for planting strawberries in the greenhouse is better in autumn and September, planting according to the triangle. As the follow-up growth, so planting should consider the strawberry growth density, not too tight, about 5000-7000 seedlings per mu is the most suitable. Remove residual leaves and weeds from the land before planting so as not to affect subsequent planting.

3. Management

After the planting is completed, watering is very important. It needs to be watered twice a day. The air in the greenhouse is not higher than outside, and the temperature will be higher. Until the small strawberry seedlings have survived, the work can not be relaxed. Wait until the seedlings have survived, you can start to apply fertilizer and water, adding nitrogen, phosphorus and potassium compound fertilizer can provide nutrition for strawberries.

4. Cover the membrane

Because the temperature in the greenhouse is higher than outside, it will keep strawberries warm, so it is necessary to cover the strawberries with plastic film. Cover film will generally choose opaque black vinyl film as the main, can be a good shade.

5. Diseases and insect pests

As the temperature in the shed is high, and the humidity is also relatively large, it is easy to breed powdery mildew, gray mold and so on. Don't panic when you encounter such diseases and insect pests. The purchase of sulfur fumigant and fumigation at night once a week can effectively control the above diseases and insect pests.

6. Temperature

During the expansion period of strawberries, temperature control is very important. During the day, the temperature in the shed needs to be controlled at about 25 degrees. It snows coldly in many areas of the north, and the temperature difference is great, so we can't underestimate the temperature difference. At night, the temperature should be controlled above 5 degrees and the humidity should be kept above 50%. If the temperature is too high, the strawberries will grow faster and the fruit will become smaller.

7. Harvest

After the strawberries slowly become red-eyed and grow to medium well, we can arrange the harvest. When harvesting, we should also pay attention to controlling the temperature of the storage room and keep the strawberries in good packaging before they can be safely delivered to dealers and customers.
