| 摘 要： | 为了提高设施温室种植草莓的生产效率和产品附加值，以草莓品种‘红颜’为试材，在冬季设施温室内，通过叶面喷施的方式以秸秆源提取物对草莓植株进行处理，探讨不同喷施量的处理对草莓的产量、单果质量、感病率和采后果实的可溶性糖、尤其是抗坏血酸、花青素、总酚物质等抗氧化性营养指标的影响。结果表明：叶面喷施秸秆源提取物的最适喷施方法为：用量1 200 mL/（hm2·次），每隔10 d喷施1 次，共喷施3 次，能够显著提高草莓果实的产量、单果质量和营养品质，尤其对果实抗坏血酸含量的提高作用最明显，草莓果实的商品价值得到了显著提升。 |

| Abstract: | Straw extract was sprayed on the leaves of strawberry fruits to explore the effect of different treatment doses on the yield, single fruit weight, infection incidence, and soluble sugar content, especially antioxidants (ascorbic acid, anthocynidin, and total phenols) of strawberry fruits. The results showed that the optimum spraying conditions of straw extract were 1 200 mL per hm2 once every 11 days for three doses. Under these conditions, the yield, single fruit weight, and nutrients, especially ascorbic acid of strawberry fruits were significantly improved, and the commercial value of strawberry fruits was greatly enhanced. |
| Keywords: | strawberry yield disease antioxidant ascorbic acid |
