遮阴处理对草莓生长发育及果实品质的影响

Effects of shading on the growth and quality of strawberry

设计不同遮阴度处理对春夏季草莓(Fragaria ananassa Duchesne)生长情况进行试验,研究不同遮阴处理对草莓生长发育及果实品质的影响。结果表明,不同遮阴处理对春夏季成熟草莓的生长发育、花期质量、果实产量和果实品质都有明显影响。在20%轻度遮阴处理下,草莓植株生长发育状况、花期、果实产量和品质都达到最佳;在40%中度遮阴处理下,草莓叶片叶绿素a和叶绿素b含量最高;在60%重度以上遮阴处理下,草莓各项生长指标均有明显下降。

The growth of strawberry(Fragaria ananassa Duchesne)in spring and summer was studied under different shading treatments. The results showed that different shading treatments had significant effects on the growth and development,flowering quality,fruit yield and fruit quality of mature strawberry in spring and summer. Under the condition of 20% light shade,the growth and development status,flowering period,fruit yield and quality of strawberry were the best;Under 40% moderate shade,the content of chlorophyll a and b in strawberry leaves was the highest;Under the condition of more than 60% shade,the growth indexes of strawberry decreased significantly.
