Key Points of Strawberry Management in October In October, strawberry planting has basically been completed. The management of plant before mulching and related technologies before mulching is also the flowering preparation period. Good management can lay a good foundation for future high yield.~ 10Moon Festival: Cold Dew First Frost 1Fertilizer and water management Watering: After planting, the soil should be irrigated with enough fixed-root water. After planting, the soil surface should be dry and wet, and small water should be irrigated regularly to keep the root moist and prevent drought until the seedlings survive. After returning to seedling, it is necessary to strengthen the management of fertilizer and water, control water and nitrogen, and prevent seedlings from growing too long.In order to form a good root system, but also conducive to flower bud differentiation.Growing at the same time3-5After a new leaf, control water properly7-10Squat seedling treatment in Tianyi Fertilization Promotes Flower Bud Differentiation After strawberry stems and leaves began to grow, after about a month, about four new leaves, inflorescence began to appear. Fertilizer fertilizer should be applied before flower bud differentiation of strawberry. Fertilizer application in this period can ensure the normal growth of strawberry plants and flower bud differentiation.Major Application of Phosphorus and Potassium Fertilizer Spraying potassium dihydrogen phosphate on the leaves when three new leaves were fully expanded could inhibit the excessive absorption of nitrogen fertilizer in strawberry and prevent the delayed flower buds caused by excessive vegetative growth of strawberry seedlings.800times+Hai Ke Lai1000times After 45 days of planting, the first topdressing was carried out. Balanced water-soluble fertilizer was applied per mu. According to the actual growth of strawberry seedlings, the amount of fertilizer could be fixed, and a small amount of topdressing could be applied many times.10kg+Melefon500times One or two times of liquid boron (1500 times) and calcium glycol were used half a month before flowering to ensure the smooth differentiation of flower buds and prevent the deficiency of calcium and boron in budding stage. 2Agricultural operations Timely cultivation and weeding, removal of old leaves and seedling repairWait for work. For the first time, the depth of middle tillage is about 1 cm, and only the hard crust part of the topsoil on the surface of the loose border is tilled in middle tillage. In the middle of this month, the depth of middle tillage is about 2 cm. In practice, the principle is not to damage the root system of strawberry. In order to save nutrients and promote flower bud differentiation and plant growth, it is necessary to remove dry and old leaves in time and the creeping path that emerges at the same time.Old leaves that have already withered should be removed from the sheath. Leaves that have not withered should be cut off with scissors first, and then removed from the sheath when the petiole is yellow. Where seedlings are deficient or dead, the seedlings should be repaired in time to ensure that the seedlings are well-developed and strong, and the roots should be irrigated in time to prevent diseases. 3Disease and pest control Before mulching, we should focus on the prevention of anthrax, root rot, powdery mildew, thrips, aphids, spiders and other highly pathogenic pests. We should focus on the prevention and control according to the actual occurrence of diseases and insects. After transplanting7To proceed within days1Sub leaf spray (first disinfectant).3Take pesticides the next day, and then each time.7Heaven beating1second。 anthraxProchlorazole spraying, spraying through the base of stem and surrounding soil, combined with Difenoconazole leaf spraying control.

It is suggested that the best medicine should be sprayed at the middle a
