摘要：为了提升草莓生产后期果实品质，通过叶面喷施不同浓度（0.5、1.0、1.5 mmol/L）硅酸钠，研究草莓生长后期植株长势以及果实硬度、品质和产量的变化情况。结果表明：喷施1.0 mmol/L硅酸钠处理效果最好，生长指标、品质指标和产量指标均表现较好，且抑制了植株徒长，与CK相比较，草莓株高显著降低11.1%，茎粗显著增加15%；喷施后10 d新叶叶绿素生长量增大80%，果实硬度变化幅度增加 6%；8成熟、9成熟、10成熟果实硬度分别显著提高65.9%、81.5%、86.8%，果实糖度分别增加8.70%、3.17%、10.77%；平均单果质量、行产量、测产行产量分别增加2.8%、12.9%、8.0%，畸形果率则降低3.6百分点。建议在草莓结果后期酌情使用。

Abstract: In order to improve the fruit quality of strawberry at the later stage of production, different concentrations of sodium silicate (0.5, 1.0, 1.5 mmol/L) were sprayed on the leaf surface to study the changes of plant growth, fruit hardness, quality and yield at the later stage of strawberry growth. The results showed that 1.0 mmol/L sodium silicate treatment had the best effect, and the growth indexes, quality indexes and yield indexes were better, and the plant spindling was inhibited. Compared with CK, the plant height of strawberry significantly reduced by 11.1%, and the stem diameter significantly increased by 15%. After 10 days of spraying, the chlorophyll growth of new leaves increased by 80%, and the change range of fruit hardness increased by 6%. The hardness of 8 ripened, 9 ripened and 10 ripened fruits significantly increased by 65.9%, 81.5% and 86.8%, respectively, and the sugar content increased by 8.8%, 1.9% and 10.8%, respectively. The average fruit weight, row yield and measured row yield increased by 2.8%, 12.9% and 8.0% compared with CK, respectively, and the malformed fruit rate decreased 3.6 percentage points. It was recommended to use at the later fruiting stages of strawberry.
