| 中文摘要: |
| 梨黑斑病是梨树重要的病害之一，本文以翠冠梨为试材，在生长季节喷施HSAF生物产品研究HSAF在田间防治梨黑斑病的效果。结果表明：田间喷施20礸/mL HSAF对翠冠的梨黑斑病有显著的防治效果，控制翠冠梨的病情指数在3.80以下；喷施HSAF能够显著提高翠冠梨的果实品质，喷施后可溶性固形物含量提高1%、可滴定酸含量提高0.02%、可溶性糖含量提高1%。 |
| 英文摘要: |
| Pear black spot is one of important diseases of the pear. Pyrus pyrifolia Cuiguan pear was used as experiment materials in this paper, effect of HSAF on controlling pear black spot in the field was studied by spraying HSAF biological products in the growth season. The results showed the effect of spraying 20礸/mL HSAF on controlling pear black spot was most significant in the field. Index of disease of Cuiguan Pear was controlled below 3.80. The fruit quality of Cuiguan Pear could be significantly improved by spraying of HSAF. After spraying the soluble solids content was increased 1%, the titratable acid content was increased 0.02%, and the content of soluble sugar was increased 1%. |
