Biological Observation And Research Of Bagging Techniques Of Introduced Varieties Peach In Biyang County

The biological characteristics, bagging were studied of 10 peach cultivars in this paper, such as'Zhongguoshahong','Ribensongsen','Xinchuanzhongdao','Mantanghong'and so on, which were introduced to biyang county as new cultivars. The results showed that:Firstly, the'Zaomei'displays the early mature and high yield in this area, the colorful surface, longer shelf life and transportation and compatible, so the comprehensive character surpasses'Chunlei'obviously, but its develops in a proper scale, because the period of fruits mature are different, which pay more attention to pick at different times. the performance of'Chuyan'is opened, high fruit–setting rate, the crop stable production, the crisp and sweet fruit and goes on the market when are mature in July, which is completely mature when the feeling in the mouth is better and the prematurely dropped fruit and dehiscent fruit phenomenon before picking is uncommon, longer shelf life and ease of transportation, which overcome the shortcomings of'Chunlei'peach slightly, weak taste and soft nucleus, so it is worth promoting. The comprehensive character good varieties are'Shahong','Ribensongsen'and'Mantanghong'. Its show vigorous and healthy of the tree condition, flower formation, high output, big and neat fruit ,the sweet color, high fruit hardness and the long shelf life in three cultivars, so its develops massively. otherwise the output is very low. In this local peach, using bag technology played role in the reduced dehiscent fruit, the disease-carrying insect fruit and the promotion coloration.Secondly, Due to the problems of poor fruit quality disease and pest fruit rate sharply increasing after bag removed as well as paper hag broken by rains etc., laying light reflecting film, choice of date of removing the bag and kind of bag used were carried out in a peach orchard for studying their effects on the fruit quality in this experiment. The results showed that laying light reflecting film on the ground could improve fruit quality and decrease the bad effects of weak light in Biyang. Removing bag 3 to5 days, no more than 7days before harvest could get fruit with ideal appearance and suffer from less pests and diseases. Peach fruit bagged with double—layer paper bag(with red inner layer and brown outer one)could make the fruit skin smoother, coloration brighter, diseases and pests fewer and as well as cracking fruit fewer.
