以“红颜”草莓作为试验材料,用遮光度为40%、60%、80%的遮阳网分别对草莓幼苗进行遮阴处理,研究遮阴对草莓花芽分化的影响。结果表明:遮阴对草莓花芽分化时期有明显影响,但不影响植株正常的生长发育。不同程度的遮阴处理都促进了草莓花芽的提早分化,其中遮阴度为40%的处理效果最好,比对照提早9d开始花芽分化,其他处理均提早6d开始花芽分化。
Strawberry was used as test material to shade the strawberry seedlings with shading degree of 40%, 60% and 80% respectively. The effects of shading on flower bud differentiation of strawberry were studied. The results showed that shading had a significant effect on strawberry flower bud differentiation but did not affect the normal growth and development of the plants. Different degrees of shade treatment promoted the early differentiation of strawberry flower buds, of which the shading degree of 40% was the best, the flower bud differentiation started 9 days earlier than the control, and the other treatments all started flower bud differentiation 6 days earlier.
