Winter Management Techniques of Strawberries in Steel Sheds

Strawberries are highly nutritious and highly effective products. In recent years, the area for planting strawberries has been expanding year by year, which has become an effective way for farmers to adjust planting structure and increase income. Here are the highlights of the winter management techniques for the strawberry steel racks.

First, the greenhouse temperature and humidity management throughout the growth period to reduce the humidity within the greenhouse as much as possible, especially in the winter flowering period when the relative humidity dropped to 50% to 60%. After buckling the greenhouse for 7 to 10 days, the black mulch is covered on the surface of the mulch and all or part of the mulch is covered, which can effectively reduce the humidity in the shed, but also has the effects of heat preservation and weeding.

Second, water and fertilizer management years before fertilization 1 time intervals of about 20 days, once a year can be a month. Fertilization is often combined with irrigation. Irrigation generally uses under-film drip irrigation to reduce the humidity in the greenhouse. It is also possible to perforate the mulch at 20 to 25 cm along the middle of the hoe surface, and then apply water on the mulching film. The side of the river seeps into the bowl.

Third, the management of the plant The top inflorescence of each strawberry plant 6 to 7, after the inflorescence of the amount of fruit depending on the growth and harvest conditions may be. Before and after the size of the fruit should not be more than 15 students. The removal of old leaves and harvested peduncles at any time in combination with sparse buds and sparse flowers.

Diseases, pests, and weeds The disease prevention and control mainly includes powdery mildew and gray mold. Powdery mildew was sprayed with 20% triadimefon WP 1000 times. The control of gray mold was selected after the baiting, and the smoking agent such as smoked smoke or smoked spirit was mainly smoked. Aphids were sprayed with 1500-fold solution of 5% beta-cypermethrin.
