At present, strawberries are mainly planted in greenhouses. Strawberries in greenhouse should be selected with shallow dormancy, good quality, high pest resistance and high yield, which are suitable for greenhouse planting, such as Zhangji, Hongyan and Fengxiang. In addition, in the strawberry field, it is best to plant 4-5 varieties, multiple varieties, and the yield of strawberries can be greatly improved. In the process of mixed planting in strawberry fields, early-maturing strawberries and middle-maturing strawberries should be mixed to disperse the peak picking period.
2. Site selection
Fields that have not been planted with strawberries for many years should be chosen as Honda for strawberry production in greenhouse.
3. Base fertilizer
Apply sufficient organic base fertilizer in the field, and about one month before planting, generally apply 1500 ~ 2000 kg of fully decomposed organic fertilizer per mu as base fertilizer, and plough and harrow for many times.
Step 4 make a cup of tea
Before construction, 50 kg of imported ternary compound fertilizer and 50 kg of calcium superphosphate were applied as surface fertilizers, and phoxim granules 10 kg were applied per mu to control grubs and other pests.
5. Planting time
Strawberry growers basically adopt the planting method of "planting one plant a year", that is, planting in early September, picking up the shed in late April of the following year, then flooding the garden and sealing the shed, leaving it idle until mid-August to start fertilizing, ploughing and ridging to prepare for strawberry seedling cultivation in September.
6. Planting method
The row spacing of greenhouse cultivation is 25-30cm, the plant spacing18-20cm, and the double-row triangular planting is implemented, with 6500-8000 plants per mu. In addition, to master the planting depth, it is required to be deep without burying the heart and shallow without exposing the roots. The suitable distance between seedling center and soil surface is 0.5~ 1.0cm. Strawberry seedlings should be planted after 3 pm on cloudy or sunny days, and old leaves should be planted before planting.
