抑制翠冠梨果实锈斑产生的研究

Studies on Improvement of Appearance Quality in Cuiguan Pear

根据梨果锈发生的原因分析,于2001～2003年对翠冠梨果实一方面通过套不同纸袋类型和采取不同套袋时间,另一方面通过套袋前的不同处理,采用综合处理技术进行了提高翠冠梨果实外观品质的试验。从综合效果上看,在花后3～4周期间,采用自制果面涂布药剂涂布果面,待药液干后,套用外黄褐内黑双层b纸袋能有效地抑制翠冠梨果面锈斑产生,达到乳白色果面的全无锈果,无锈果率可达80.0%。

Based on analysis of causation of rust spot on pear surface, the orchard tests on improvement of appearance quality in fruit surface of Cuiguan pear were conducted by integrated treatments of putting on different kinds of bags at different period with different disposals to fruit before bagging in 2001 to 2003. Results showed that during 3 to 4 weeks after flowering, the self-made drug liquid was smeared on the fruit surface, then after the drug liquid was dry, bagging the double-layered paper bag b with outer yellow and brown and inner black on the pear fruit could effectively prevent the production of rust spot on pear surface and make the surface purely white with no rust, with the no rusty fruits of 80.0 %.
