However, if you plant a greenhouse, you must transplant new seedlings every year. Because the greenhouse is damp and cold, it is easy to breed bacteria. After strawberry bears fruit, it is necessary to disinfect the greenhouse to solve the control diseases, which can increase the yield and achieve high quality. In addition, there should be a certain area between rows and plants in the greenhouse, and crawling is not allowed, so new seedlings should be planted every year.
Under normal circumstances, all the original seedlings will be shoveled off every year, and then new seedlings will be replanted. This is the key cultivation method in production and manufacturing at present, that is, one-year planting system. Generally, strawberry seedlings are sown from early August to early September of the previous year, and the first fruit is gradually harvested from 65438+February, and the fruit harvesting period can last from May to June of the following year. After the fruit is picked, the main stem is removed, other food crops are planted, and new seedlings are planted in this place.
When buying strawberry seedlings, choose more roots and leaves that look fresh. When you dig out strawberries under transplant, be careful not to hurt the roots. Better bring more layers of soil. It's easier to survive that way. Pull up dead leaves. The withered roots are also removed.
In order to sell better before the Spring Festival, strawberries can be transplanted into greenhouses every September. You can't transplant it casually during the transplant process. If you don't plant them for a long time, it will bring problems to the seedlings. Knowing the relative density of planting can be transplanted. Generally 1 mu can plant 12000 plants, and it must be watered every day after planting. Moreover, it is very important to use water for irrigation and planting. In addition, in the case of transplanting, to ensure that the roots have penetrated into the soil, it is best to buckle the shed. The tent-fastening period is generally 1 1 month.
Moisturize and replenish water in North China, from mid-late September to mid-early June, 10, and gradually buckle the membrane to keep warm. In winter, strawberries can be covered with leaves in addition to two-way heat preservation in greenhouses and small plastic greenhouses. According to the temperature and humidity management regulations, maintaining 25℃ ~ 30℃ during the day and 12℃ ~ 17℃ at night in the early stage after planting is beneficial to early fruiting. Results The temperature should not exceed 20℃ ~ 25℃ during the white ceiling period and not lower than 5℃ at night (the total temperature control goal is 10℃). The air humidity should be about 50%, and the ambient humidity should be controlled by ventilation.
