用扑海因(Iprodione)、Metamedan和敌菌丹(Captafol)在开花期和果实形成期,田间每周喷药一次,模拟海运后上市的过程作10天贮藏(2℃)和置货架2天(20℃)后,草莓(品种Aliso)的灰霉病明显减少。未经药剂处理小区中收获的新鲜草莓封存在能渗通空气的聚乙烯(PVC)塑料袋内,能明显改进贮藏期草莓的品质、更好地保持草莓硬度、降低水份损失、延缓草莓花萼干燥、明显降低草莓灰霉病的发病率。草莓贮藏品质的改进与PVC装内Co_2的富集有关。PVC膜使Co_2积累至高浓度(10.5％),是控制贮藏期草莓灰霉病最有效的措施。在此Co_2浓度下,草莓的本味不会丧失。采果前用扑海因杀菌剂处理与PVC封藏相结合,比单用PVC袋藏更能提高对灰霉病的防治效果,而且延长存贮期中亦能非常有效地延缓生理性和病理性腐烂。
Iprodione, Metamedan and Captafol were sprayed once a week in the field during the flowering and fruit-forming phases to simulate the process of going to sea after 10 days of storage (2 ° C) and shelving for 2 days (20 ℃), the gray mold of strawberry (Aliso species) decreased significantly. Fresh strawberries harvested in a non-medicated area can be stored in a polyethylene (PVC) plastic bag infiltrated with air to significantly improve the quality of the strawberry during storage, to better maintain the hardness of the strawberry, to reduce the water loss and to delay the growth of the strawberry calyx Dry, significantly reduce the incidence of strawberry gray mold. The improvement of storage quality of strawberry is related to the enrichment of Co_2 in PVC equipment. The accumulation of Co_2 to high concentration (10.5%) by PVC membrane is the most effective measure to control gray mold disease in strawberry during storage. In this Co_2 concentration, the natural flavor of strawberry will not be lost. Pomegranate fungicide treatment with pvc closure combined with pvc bagging can improve the control effect of botrytis cinerea, and also prolong the storage period can also be very effective in retarding the physiological and pathological rot.
