摘要
1999～ 2 0 0 0年进行了在草莓的盛花期、幼果期分别喷施 30 0 0倍、4 0 0 0倍 5 0 0 0倍云大— 12 0水溶液的试验。结果表明 ,喷施后可提高草莓叶片的叶绿素含量和净光合速率 ;增大单果重 ,提高果实含糖量、Vc含量 ,降低果实的含酸量 ;增大果实糖酸比。以 4 0 0 0倍处理的经济效益最高。
The changes of physiology factors in leaves and fruit qualities in strawberry were studied by spraying on leaves during full bloom and young fruit stage respectively in 1999-2000?Results showed that the content of chlorophyll,net photosynthetic rate in leaves, the individual fruit weight and the content of sugar and Vitamin C and sugar-acid ratio in fruit were increased. While the content of acid in fruit was decreased. The economic effect was the highest by spraying 'yunda-120'in 4000X in strawberry.
