October strawberry management can produce high yield
Weeding and repairing
In October, the grass on the strawberries must be removed in time to avoid competing with the strawberries for nutrients. Due to frequent weeding and watering, the strawberry squash is damaged, the scallops are narrowed, and the indole swells. At this point, the strawberry sorghum should be refurbished.
Soil and Fertilizer Water Management
After controlling the water, the watering is based on the principle of "see dry see wet". There are more rains in autumn, and the soil has high humidity. In particular, we must pay attention to water control and disease prevention. Management should not only control the water but also maintain a certain degree of soil moisture to prevent the soil from overdrying and affect the normal growth of the strawberry seedlings. Watering should be performed around 8:00 AM.
Fertilizer control During this period, the strawberry enters the flower bud differentiation stage. In order to prevent overgrowth and delay flower bud differentiation, it is necessary to properly control the use of nitrogen fertilizer, increase the use of phosphorus and potassium fertilizers, and promote flower bud differentiation. Foliar supplements and top-dressing fertilizers should be used. Foliar potassium dihydrogen phosphate should be used to supplement nutrients, increase resistance and promote growth. When the strawberries are about to be buckled, the compound fertilizer will be applied once and the dosage will be 10-20 kg/mu.
The first cultivator cultivator has a depth of 1 cm or so. When cultivating, only the topsoil of the topsoil of the pine buckwheat noodles will be ploughed by about 2 centimeters during mid-cultivation in the middle of this month. The actual operation does not harm the strawberry roots.
New seedling management
Removal of Old Leaf Disease Leaf When the new leaf of strawberry grows, the dry old leaf is removed promptly, and at the same time, the diameter of the extracted borer must be removed in time to save nutrients and promote flower bud differentiation and plant growth. The old leaves that have withered must be removed from the leaf sheaths. The leaves that have not withered must first be cut with scissors and then removed from the leaf sheaths when the petiole is yellow.
Supplementary seedlings due to more rain in autumn, many fields were soaked in rain, if the pharmaceutical control is not timely, strawberry seedlings with serious disease, will result in seedlings after planting death, the lack of seedlings and dead seedlings should be promptly filled seedlings to ensure seedlings Qi Miao.
Timely buckled plastic film and film
The best time of greenhouse insulation in the northern region is from early October to mid-to-late October. At this time, the minimum ambient temperature is reduced to 8°C to 10°C. The insulation of the southern greenhouse shed is generally before the first cold air arrives, probably from the end of October to the beginning of November, when the average temperature of the outside world drops to 15°C.
About 1 week after the film is buckled, the film should be buckled to reduce the humidity of the air to keep the soil moisture and prevent the ground temperature from decreasing. Insulation is not conducive to flower bud differentiation too early. Insulation is too late Once the plant enters dormancy, it is difficult to release dormancy, which results in dwarfing the plants.
Strengthen pest control
Due to the fact that there is a lot of rain this autumn, the humidity is high, which is conducive to the occurrence of diseases. For places where strawberry is colonized later, the occurrence of yellow wilt disease, powdery mildew, and anthrax is relatively serious. Attention should be paid to timely prevention and treatment.
After the strawberry is planted and vegetated, the nutrient bactericidal No. 1 combined with adjuvant No. 1 and full complement fertilizer No. 1 are sprayed alternately every 5 to 7 days. During the spraying process, not only the strawberry seedlings and sorghum but also bares are sprayed. The ground is sprayed together and the spread of germs is completely eliminated until the strawberry shed is covered, which can effectively prevent and control the occurrence of diseases. Control locusts: imidacloprid or wolfberry No. 1, etc., spray once every 7 to 10 days, at the same time we must timely remove the greenhouse and surrounding weeds, get rid of locust habitat.
Disposable gloves are available in latex and synthetic materials, in sterile and non-sterile forms and with and without powder. Sterile disposable gloves should be worn during invasive procedures and when the hands are in contact with wounds. Non-sterile disposable gloves are recommended when the hands are in contact with blood and other body fluids and for indirect contact with wounds.
