Technology of planting strawberries in greenhouse

1. Select suitable varieties or mixed planting of different varieties to choose Fengxiang and Mingbao with more flowering, large amount of pollen, large and neat fruit, good coloring, light sour taste and less abnormal fruit under the condition of low temperature. Varieties such as Qiuxiang, Baojiao Zaosheng and all-Star have less pollen and more abnormal fruits. Chunxiang, Dana and other varieties should be planted as pollination plants to facilitate pollination and fertilization, reduce abnormal fruits and improve the rate of big fruits.

two。 The disease-free strong seedlings have developed root system and strong disease resistance, and the strawberries produced are large, high yield and good quality.

3. Adequate application of high-quality basic fertilizer and high-quality mature farm manure can provide sufficient nutrients for strawberry growth, flower bud differentiation, flowering and fruit setting and fruit development, increase fruit number, and improve fruit sugar content and color. 2000 kg of rotten chicken manure is applied per mu, and ditch application is combined with spreading.

4. The implementation of crop rotation to avoid continuous cropping can improve the disease resistance of strawberries and reduce the number of deformed fruits and insect pests. The open-ground rotation between the shed and the shed can be made full use of.

5. The lack of light from 2 weeks before flowering to the flowering stage of strawberry will affect pollination and fertilization and produce deformed fruit. Lack of light during the coloring period will lead to light taste and poor color of the fruit. Under the premise of ensuring the temperature in the shed, the covered grass should be uncovered as early as possible. A reflective screen is hung on the north side of the greenhouse, which uses reflected light to increase illumination. On rainy or snowy days, incandescent lamps can be used to make up the light.

6. Ridging cultivation and plastic film mulching ridging cultivation can reduce fruit dripping contact with greenhouse film, enhance sunlight exposure to fruit, reduce the occurrence of Botrytis cinerea and promote fruit coloring. Plastic film mulching can increase soil temperature, reduce air humidity, avoid direct contact with soil, and help to keep fruit surface clean.

7. The suitable greenhouse temperature was 22: 25 ℃ at flowering day, 8: 10 ℃ at night, 20: 24 ℃ at day and 6: 10 ℃ at night during fruit expansion. Too high temperature in the greenhouse will shorten the fruit development period and make the fruit smaller.

8. Appropriate amount of watering and topdressing is suitable for drip irrigation in flowering and fruiting period. Insufficient moisture during flowering will lead to poor pollination and fertilization, resulting in deformed fruit. The lack of water during the fruit expansion period will affect the fruit expansion. During flowering and fruiting period, 0.3% potassium dihydrogen phosphate solution should be sprayed continuously for 3 times for 4 times.

9. Poor fertilization by auxiliary pollination is the root cause of abnormal fruit, and the use of bee-assisted pollination can effectively reduce the production of abnormal fruit. Generally, one case of bee pollination is put in each greenhouse during flowering.

10. Timely prevention and control of diseases and insect pests strawberry during flowering is easy to induce abnormal fruit. If diseases and insect pests occur during the flowering period, spray the beehive out of the greenhouse before spraying, and then move back to the greenhouse 1 week after spraying.

Japanese Strawberry Company in Fujita: the cultivated area is equivalent to the area of three football fields. And the size of a strawberry greenhouse is 1.7 hectares, which can be said to be the largest strawberry garden in Japan.

This strawberry orchard is located in Fujita City.

Agricultural production legal person "Japanese Strawberry" is a strawberry production group jointly established by three farmers in Zhitai Hazelwon area in the 15th year of Pingcheng.

I interviewed the person in charge of the representative, Mr. Yoshiyou Uamayama.

Yu Shangshan is now the chief director of the county agricultural management association.

"the three of us are tea farmers who grow tea and lettuce, tea and strawberries, and tea and mushrooms," he said. Of course, we still continue to grow tea. Our main goal of operating this large-scale strawberry production is to achieve "sustainable agriculture", to build an integrated system from production to sales, to expand employment opportunities and to achieve profitable operation. "

One member who had previously planted strawberries was in charge of cultivation techniques, the uphill was responsible for planning and business, and the other was in charge of accounting. Everyone gives full play to their own talents to carry out the operation of the strawberry garden in the form of division of labor and cooperation.

In recent years, strawberry farmers from China have even asked them to "give guidance" on the establishment of a large-scale management system and cultivation techniques.

The strawberry varieties cultivated here are "Red cheek Strawberry", "Zhang Yi", "Sagahonoka" and "Kaorino", all of which are cultivated by elevated construction.

They are committed to growing strawberries that are "as ripe as possible on strawberry trees" and "strong flavor".

Fresh strawberries and processed strawberry jam can be bought at the outlet store here.

In addition, they also ship goods directly to the and-style pastry shop and cake shop. The strawberries in the photo on the right are provided to Kashiharu, the dim sum shop, to make strawberry Dafu snacks.

It also serves as a sightseeing farm for tourists to pick strawberries. As soon as the weekend arrives, you can see many tour buses.

Go up the mountain and say, "because of the elevated cultivation and barrier-free design, even guests in wheelchairs can enjoy picking strawberries!"

Welcome to this spacious strawberry shed to taste fresh and delicious strawberries! "

It's great that the strawberry shed is so spacious.

Because the strawberry orchard is very clean, it is easy to pick strawberries standing up. The strawberries just picked are delicious!
