近年,本市从台湾、日本等地引进了东升、埃皮斯等南瓜杂种1代,由于其肉质致密,食味绵甜而受到消费者的广泛欢迎。然而,这类南瓜新组合收获期短而集中,且不耐高温,因此,市场供应期也较短。为了延长优质南瓜的供应期以及提高菜农的生产效益,我们开展了南瓜涂胶保鲜试验。 一、材料与方法 1996年在嘉兴市农科所进行试验。以东升南瓜作试材,由浙江省农作物引种中心乔司农场试验场提供。5月17日收获,当天运回嘉兴,并选择成熟度接近的大小为1kg左右的无病南瓜。涂胶分三种处理方式:A处理:成膜剂为淀粉,配方为淀粉45g,多菌灵8g,2,4-D1g,水4000ml。混合后加冷水200ml调成稀糊状,然后加开水,边加边搅拌,冷却后即为涂被剂,现配现用。B处理:成膜剂为紫虫胶。配方为:紫虫胶 120g,多菌灵 4g,2,4-D0.5g,水 1500ml。将虫胶投到 70％的 200ml酒精中加热搅拌,待虫胶溶解冷却后加入多菌灵和2.4-D,施用时在上述 In recent years, the city from Taiwan, Japan and other places introduced Dongsheng, Episia and other pumpkin hybrids on behalf of the 1st generation, due to its meat quality, sweet taste and consumers by the widely welcomed. However, this new pumpkin combination has a short, concentrated harvest period and is not resistant to high temperatures and therefore has a shorter market supply period. In order to prolong the supply period of high-quality pumpkin and increase the production efficiency of vegetable farmers, we conducted a pumpkin coating preservation test. First, materials and methods In 1996 Jiaxing City Agricultural Experiment. To Dongsheng pumpkin for the test material, introduced by the Center for Crops in Zhejiang Joe Division farms test site. May 17 harvest, shipped back to Jiaxing the same day, and choose the approximate maturity of about 1kg of disease-free pumpkin. Glue treatment in three ways: A treatment: film-forming agent is starch, the formula is starch 45g, carbendazim 8g, 2,4-D1g, water 4000ml. After mixing add 200ml of cold water into a thin paste, and then add boiling water, while stirring, cooling is coated, now with the current. B treatment: film-forming agent for the purple shellac. Formulation: purple shellac 120g, carbendazim 4g, 2,4-D0.5g, water 1500ml. The shellac cast into 70% of the 200ml of alcohol heating stir until shellac dissolved cooled and added carbendazim and 2.4-D, when applied in the above
