摘要
实验表明,多效素等4种叶面喷施物均有提高套袋果实含糖量的作用,其原因是它们可增加叶片厚度及叶绿素含量,提高叶片光合速率,同时还降低套袋鸭梨果实的过氧化物酶活性及呼吸强度。其中叶肥1号和多效素在提高光合作用效果方面效果显著,而氨基酸复合微肥及云大-120则在降低呼吸强度方面效果较突出。
The experiment showed that 4 kinds of foliar - spraying substances such as Duoxiao-su etc increased the sugar content of Yali pear fruits. This was because they increased width, chlorophyll content and photosynthesis rate of leaves, and reduced peroxidase activity as well as respiration rate of fruits. Among these substances, Yefei 1 and Duoxiaosu had a significant effect for increasing photosynthesis rate. However, amino acid microelement fertilizer and Yunda 120 greatly reduced respiration rate of fruits.
