摘要
为探讨核桃青皮植物源营养液的优选配方，于2012年11月～2013年1月，选择草莓为试材，叶面喷施核桃青皮（Juglans regia）不同处理工艺（匀浆过滤、乙醇浸提、石油醚浸提）的2 mg/ml 粗提物及石油醚提取物的复配营养液：匀浆过滤液（处理1）；2 mg/ml 乙醇提取物（处理2）；2 mg/ml 石油醚粗提物（处理3）；2 mg/ml 石油醚粗提物＋0.2%尿素（处理4）；2 mg/ml 石油醚粗提物＋0.2%尿素＋0.2%硫酸锌（处理5）；2 mg/ml 石油醚粗提物＋0.2%尿素＋0.2%硫酸锌＋0.2%磷酸二氢钾（处理6）进行处理56 d，清水为对照，测定分析不同处理草莓果实可溶性糖含量、酸度、总蛋白含量、Vc 含量、Zn 含量等品质指标，采用平均权重法优选最优配方。结果表明：与对照组相比，不同处理草莓果实的可溶性糖含量和可滴定酸含量都增加，糖酸比均下降；除处理2、3和5外，其他复配营养液处理的草莓果实 Vc 含量均略有降低，最低为7.70μg/g；不同处理的复配营养液对草莓的总蛋白质含量无影响；不同复配营养液均有助于提高草莓果实含锌量，处理6含量最高，比对照增加7.72μg/g。综合衡量，草莓果实品质最佳果实品质分数为1.07，最低为0.70。所以，配方6为新型营养液的优选配方。生产制备兼具杀螨和提升果树品质的植物源复配营养液具有可行性。
Objective]In order to explore effects of the Juglans regia combination nutrient solution on fruit quality,the strawberry （Dianxue） was selected as materials for treatments. [Method]In this study , the soluble sugar content ,TA content,Vc content, all protein content and Zn content of strawberry were studied. [Result]The results showed that： the soluble sugar content and TA content of different treatments increased than CK . But the acid-sugar ratio of all treatments decreased .Except treatment 2, treatment 3 and treatment 5 , others displayed preventive effects on the Vc content.And the lowest content was 7.70μg/g .The Juglans regia combination nutrient solution has no effect on all protein content. In addition ,different treatments help to improve Zn content. Compare to treatment 7, Zn content of treatment 6 increased by 7.72μg/g,which reached to the max. The difference was significant in fruit quality . We valued the fruit quality based on averaging weight method,It showed the fruit quality of treatment 6 was the best ,that of treatment was the poorest（with 1.07, 0.70 respectively） .[Conclusion]The results indicated that the comprehensive functions of the treatments 6 was prior to the other treatments.It is possible to produce a kind of nutrient solution with acaricidal activity and nutrient effect.
