Strawberry management measures in winter

Strengthen the management of fertilizer and water. After planting, it should be watered thoroughly and watered continuously for 3 times to keep moist, conducive to survival, enter the rainy season, pay attention to drainage. After the planting survived, the seedlings were raised with 5 kg urea per mu and entered the vigorous growth period (stolon occurrence period). The ternary compound fertilizer was applied twice and the dosage per mu was controlled at 5 kg per mu.

Remove inflorescences, old leaves, diseased leaves. After the strawberry seedling is planted, the inflorescence of the flower bud on the mother plant is often removed to concentrate nutrients and promote the vegetative growth and stolon of the mother plant. And often remove the old leaves and diseased leaves, which is conducive to plant ventilation, light transmission, and promote the healthy growth of mother plants and seedlings.

Stolon finishing. After the mother plant is planted, it should be checked in the field frequently, and the stolons should be kept at a certain distance. When a large number of stolons occur, the stolons that are close to each other are pulled apart to make them evenly distributed and prevent crossing or overlapping. At the same time, in order to make the adventitious roots on the stolon nodes go into the soil in time, the adventitious rhizome segments on the stolons are stabilized with soil.

Ploughing and weeding. Strawberries are sensitive to herbicides and should be used with caution. In general, manual weeding is safe, from mother plant colonization to stolon occurrence, the soil is easy to harden due to frequent irrigation, so shallow ploughing and loosening soil should be adopted to facilitate the occurrence of seedlings to take root.

Pest control. The common pests of strawberry propagation seedlings are grubs, aphids, Spodoptera litura and so on. The main diseases are snake eye disease, anthrax and so on.

Grub: irrigate and kill with 1000 times of 90% crystal trichlorfon or 1000 times of phoxim EC.

Aphids: Spodoptera litura is sprayed with 10% imidacloprid 1000-1500 times or 1.8% avermectin EC 3000 times.

Anthrax, snake eye disease: use 1000 times of 70% methyl topiramate wettable powder or 75% chlorothalonil wettable powder alternately, spray once every 7 days, spray 3 Mel 4 times. Duan Yunxin
