Northern facilities cultivation of strawberries, usually in early October will be shed, in order to inhibit the dormancy of strawberries, we must artificially create conditions to promote the "early awakening", now introduce two methods for reference: Gibberellin to promote "early awakening" Afterwards, the old leaves and yellow leaves of the bottom of the strawberry were removed and the first gibberellin treatment was performed at a concentration of 5 mg/kg when the two leaves were not deployed (within a specific time within 5 days after the baiting). The concentration of dormant deep varieties can be higher, generally 10 mg/kg, and the interval between them is 7 to 10 days. The main leaf is sprayed, and the dosage should not be too large, otherwise it will cause the petiole to be too long, the leaves to stand upright, and the stalks to be slender. , resulting in reduced fruit set rate. Gibberellin is just a hormone, not a fertilizer. Underground management must not be neglected. Otherwise, imbalances in ground and underground growth balance will result. In the case of strawberries treated with gibberellin, only when they are under high temperature conditions will they receive the desired effect. Therefore, relatively speaking, the temperature of the greenhouse penicillin-fermented strawberries should be higher, usually 28 to 28 during the day. 30 degrees Celsius, no more than 35 degrees Celsius, 12 to 18 degrees Celsius at night, and no less than 8 degrees Celsius at minimum. As the facility's strawberries are warmed up in the middle and early October, the temperature during the daytime is still high. During the day, it is necessary to pay attention to ventilation and cooling. At night, look at the weather and cover the haystacks. The indoor air humidity is kept between 85% and 90%.
