湘东边缘的炎陵县,以中山地貌为主,境内海拔悬殊,气候多样。(?)李种植面积近1 000 hm2,常年产量4 500 t左右。由于南方诸省(?)李成熟期多在7 月中下旬,上市集中,应市期短,销价低,导致生产效益严重滑坡。我县2001—2002年连续两年在海拔350、850 m的区域进行套袋试验,旨在探讨套袋对(?)李成熟期、品质的影响,摸索出山区(?)李的套袋栽培技术。2003-2004年推广套袋面积120 hm2。
Yanling County, on the eastern edge of the eastern part of Hunan Province, is dominated by the mountainous terrain and has a variety of climates at different altitudes. (?) Lee planting area of nearly 1 000 hm2, perennial output of 4 500 t or so. As the southern provinces (?) Lee mature period and more in late July, the concentration of the market should be short period, low selling prices, resulting in serious loss of production efficiency. In 2001-2002, our county carried out the bagging test in the area of 350,850 m above sea level for two consecutive years in order to explore the influence of bagging on the maturity and quality of plum plum technology. 2003-2004 promotion bagging area of 120 hm2.
