蓝莓土肥水管理及病虫害防治

蓝莓栽植对土肥水要求严格，适宜土壤pH值在4．5～5．5之间，要施入硫酸铵等肥料，最好进行滴灌供水，并覆盖黑膜，以保证地面潮湿度。蓝莓容易感染枯焦病、急性坏死病、介壳虫、蛆虫、黄刺蛾等病虫害，需注意加强防治。

Effect of the Juglans regia Husk Combination Nutrient Solution on Strawberry Quality in Greenhouse

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.
