With the development of greenhouse planting technology, fresh strawberries can be eaten during the New Year. So if you want to have a high yield of strawberries during the New Year, you must act now. Weeding and repairing borders In October, weeds on strawberry borders should be removed in time to avoid competing with strawberries for nutrients. Due to frequent weeding and watering, the strawberry borders are damaged, the borders become narrow, and the borders rise. At this time, the strawberry borders should be repaired. After soil, fertilizer and water management, water control and slow seedling, watering should be based on the principle of "seeing dry and seeing wet". In autumn, there is a lot of rain and soil moisture is high, so special attention should be paid to water control and disease prevention. In the management, it is necessary to control water and keep a certain soil humidity to prevent the soil from being too dry and affecting the normal growth of strawberry seedlings. Watering should be carried out at around 8 in the morning. Fertilizer control This period of strawberry enters the flower bud differentiation period. In order to prevent excessive growth and delay flower bud differentiation, it is necessary to appropriately control the use of nitrogen fertilizer, increase the use of phosphorus and potassium fertilizer, and promote flower bud differentiation. It is advisable to use foliar fertilizer and extra-root topdressing, and spray potassium dihydrogen phosphate on the leaves to supplement nutrients, increase resistance and promote growth. When the strawberry is about to be shed, the compound fertilizer is applied once in a furrow, and the dosage is 10-20 kg/mu. The first cultivating depth of cultivating is about 1 cm, and only the hard crust part of the topsoil of the pine border is ploughed, and the depth of the second cultivating should be about 2 cm. In actual operation, the principle of not harming the strawberry root system is the principle. New seedling management When the new strawberry leaves grow out, the dry and old leaves should be removed in time, and the creeping diameters should be removed in time to save nutrients and promote flower bud differentiation and plant growth. The withered old leaves should be removed from the sheath. If the leaves have not withered, cut the leaves first, and then remove them from the sheath when the petiole is yellow. Replenishing seedlings due to heavy rain in autumn and many fields have been soaked by rain. If the medicament control is not timely, strawberry seedlings will carry pathogenic bacteria seriously, which will cause seedlings to die after planting. Seedlings should be supplemented in time to ensure that seedlings are lacking and dead. Qi Miao Zhuang. The best time to buckle the mulch film and the greenhouse film in the northern area is from early October to mid-to-late October, when the minimum outside temperature drops to 8℃～10℃. After buckling the film, buckle the mulch to reduce the air humidity to keep the moisture in the soil and prevent the ground temperature from falling. Too early heat preservation is not conducive to the differentiation of flower buds. Once the plants enter the dormant period after heat preservation, they will cause the plants to dwarf. Strengthen the prevention and control of plant diseases and insect pests In autumn, there is more rain and high humidity, which is beneficial to the occurrence of diseases. For places where strawberries are planted late, fusarium wilt, powdery mildew and anthracnose are more serious, and timely control should be paid attention to. After strawberry planting and slow seedlings, apply Nutrition Sterilization No. 1 with auxiliary agent No. 1 and Quanbufei No. 1, alternate spraying every 5 to 7 days. During the spraying process, not only the strawberry seedlings and border surface, but also the exposed Spraying on the ground at the same time can completely prevent the spread of germs, until the strawberry shed is blocked, which can effectively prevent and control the occurrence of diseases. Prevention and control of aphids: Imidacloprid or Aphids Thistle No. 1 etc., spray it every 7 to 10 days. At the same time, weeds in and around the greenhouse must be removed in time to remove the habitat of aphids.
