| 中文摘要: |
| 以湘南梨为试材，于盛花期喷施PBO和福星不同处理，研究PBO和福星对湘南梨脱萼果率、果实品质和单株产量的影响。结果表明：喷施浓度为300倍 PBO和6000倍福星混合处理脱萼效果差异最为显著，脱萼果率为73.90%；单独使用PBO处理脱萼率为47.60%；两种脱萼处理均能够显著提高梨果的可溶性固形物和可溶性糖的含量，增加梨果的果肉硬度，降低果形指数，改善梨果外观品质，但对梨树的单株产量的影响差异不显著。 |
| 英文摘要: |
| Pyrus pyrifolia Xiangnan pear was used as experiment materials in this paper, and effect of PBO and nustar (40% Flusilazole EC) on the ratio of the fruit without calyx, fruit quality and per plant yield were studied by spraying at full bloom stage. The results showed the effect of shed calyx was most significant by spraying with 300 times PBO and 6000 times nustar solution, and the ratio of the fruit without calyx was 73.90%. The ratio of the fruit without calyx was 47.60% by spraying 300 times PBO alone. Two calyx treatment could significantly increase the soluble solids content of pear and soluble sugar, increased fruit flesh firmness, reduce the fruit shape index, improve the appearance quality of pear, but did not significantly affect the per plant yield of pear. |
