为提高草莓产量和质量,生产中除采用各种栽培技术和保护措施外,还可用植物激素调节草莓的生长发育。 1、促进花芽分化低温和短日照条件能促进草莓花芽形成。但保护地栽培,或定植时气温过高,植株会生长矮化,花芽分化减少,开花结果亦少。为促进花芽分化,定植后每株喷洒5~10PPm赤霉素溶液5毫升,间隔7~10天后新芽萌动时可再喷洒1次。据试验表明,在花芽分化前两星期,用25~50PPm赤霉素喷洒,能使花芽早分化5~10天。但喷洒过早,效果不明显,而过迟,虽能提早开花,却易发生畸形果。
In order to improve strawberry yield and quality, besides using various cultivation techniques and protection measures in production, plant hormones can also be used to regulate the growth and development of strawberries. 1, to promote flower bud differentiation Low temperature and short-day conditions can promote strawberry flower bud formation. However, when cultivated in protected areas or when the temperature is too high at the time of colonization, the plants will grow dwarfed, flower bud differentiation will be reduced, and the flowering result will be less. In order to promote flower bud differentiation, spray 5 ml of gibberellin solution 5 ~ 10PPm after planting, and sprout 1 time after 7 ~ 10 days interval. According to the test, two weeks before flower bud differentiation, spraying with 25-50 g gibberellin can make flower buds prematurely differentiate for 5-10 days. However, spraying too early, the effect is not obvious, but too late, although early flowering, but prone to deformities.
