丁岙杨梅上应用防虫帏与避雨棚结合技术对果实品质的影响

摘要

Maturation period of Myrica rubra cv. Dingao fruit coincides with the summer rainy season,high temperature and high humidity leads to preharvest drop seriously,drosophila number large occurance,fruit quality bad.In view of this situation,the pest control curtain and lew combination technology of cultivation test of Myrica rubra cv. Dingao single tree was carried out. Through the determination of fruit weight,soluble solids,titrable acid content,sugar content,the accumulation of drosophila number index in open cultivation and rain shelter cultivation Myrica rubra cv. Dingao,the effect of pest control curtain and lew combined technology on fruit quality of Myrica rubra cv.Dingao single tree was investigate.The results showed thatpest control curtain and lew combined cultivation technology of single tree fruit weight had not obvious difference,but the soluble solids content,titratable acid content,sugar content,the number of the accumulation of drosophila defense was better than the control,and this technology was worthy to be popularized in production.%丁岙杨梅果实成熟期恰逢夏季梅雨季节，高温高湿导致采前落果严重，果蝇数量大量发生，果实品质差，针对此情况采用防虫帏与避雨棚相结合技术对丁岙杨梅单树进行避雨栽培试验。通过测定露地栽培和避雨栽培丁岙杨梅果实的单果重、可溶性固形物、可滴定酸的含量、各糖成分积累量、果蝇数量等指标，探讨防虫帏与避雨棚结合技术对丁岙杨梅单树果实品质的影响和防虫效果。试验结果表明：经过防虫帏与避雨棚结合技术栽培的单树杨梅果实单果重与对照差异并不明显，但是可溶性固形物、可滴定酸含量、各糖成分积累、果蝇数量防御上均优于对照果实，生产上值得推广。
