Prevent early buds and early flowers
In winter, in order to prevent early buds and early blooms of strawberries, the following points should be done in the production: First, select suitable varieties. For greenhouse cultivation, select varieties with less dormancy. If you choose a variety with strong dormancy, it should not be too early to keep warm and cover. The second is to fertilize reasonably, strengthen management, and cultivate strong seedlings in the process of raising seedlings. Measures such as removing old leaves, removing inflorescence, straightening out stolons, spraying gibberellin, etc., strengthen the management of mother plants and produce high-quality and strong seedlings. The third is to pay attention to temperature control after the shed.
Anti-deformed fruit
Mixing some varieties with a lot of pollen among the main varieties is an effective measure to prevent strawberry deformities in greenhouses. Pesticides should not be sprayed during strawberry flowering period. Drugs can be used to prevent and control the disease before the strawberry blooms, and the diseased plant can be removed in time after the flowering, and the diseased leaves and inflorescences can be removed to control the spread of the disease. When the moisture content is insufficient, the ridges should be irrigated in time with film mulching. When there is a shortage of fertilizer, apply 15 kg of 45% ternary compound fertilizer per mu with watering and do not use ammonium bicarbonate. After the fertilizer is diluted with water, the perforated topdressing effect is better. When each batch of flower buds of strawberry in the greenhouse is formed, put bees in the shed, and stock 5,000 in each standard shed, so that the pollination rate can reach 100%. The bee release time is 8-9 am and 3-4 pm.
