Strawberry fertilization technology in greenhouse
Strawberries are important cash crops, and the cultivated area in China has gradually increased, of which greenhouses occupy 2/3. Long-term continuous cropping in greenhouses will cause soil salinization and salinization. Therefore, in order to fundamentally change the strawberry planting phenomenon in the greenhouse, in accordance with the growth characteristics of the strawberry and the need for fertilization, provide systematic fertilizer technology to the strawberry in the greenhouse, thereby promoting the high yield of the strawberry in the greenhouse. Fertilization management after transplanting One week after the strawberry is transplanted, various fertilizers such as potassium nitrate, potassium dihydrogen phosphate, magnesium sulfate, and zinc sulfate are sprayed multiple times. Wait until early October to apply urea and potassium dihydrogen phosphate, depending on the growth of the strawberry, take a small amount of more application. In early November, gibberellin was sprayed during sunny periods and high temperatures to effectively break the strawberry's sleep period and promote flowering. When flower buds appear, spray trace elements such as boric acid in a timely manner, and fertilize reasonably according to the growth conditions of strawberries to reduce the incidence of deformed fruits. Two weeks before the picking, three times of foliar fertilizer containing stevioside must be applied. The main role of stevioside is to increase the sugar content of berries and adjust the sweet and sour ratio of strawberries. During the entire growth process of strawberry, liquid silicon fertilizer is sprayed to promote the growth of plant and fruit cell walls, increase the thickness of the leaves, increase the fruit's firmness, and play an important role in ensuring transportation and freshness after the fruit is harvested.

Fertilization before transplanting opened the film in August to deepen the land. During the process of ground turning, 15 kg of diammonium phosphate and 10 kg of potassium sulfate were applied. Because strawberry grows vigorously and reproductive growth is too slow in the early growth stage, it is very important to adjust the input of nitrogen and phosphorus properly. Finally, the soil should be raked down and ready for ridge cultivation.
