将京优葡萄从花前至果实采收进行不完全封闭的普通钢筋大棚覆盖,研究了大棚内的小气候环境.结果表明:1997年7月中旬上午6时至下午16时棚内温度高于露地对照,下午16时至次日上午5时低于对照;上午6时至下午13时棚内相对湿度低于露地,13时至次日上午5时高于露地.棚内京优葡萄与露地相比,座果率提高35.2%,单果重增加22.1%;至成熟采收时,果汁中可溶性固形物提高了12.7%,酸度降低,果实品质得到明显改善. The Jingyou grape was harvested from the anterior floret to the fruit and covered with ordinary steel shed which was not completely closed. The microclimate environment in the greenhouse was studied. The results showed that the temperature in the greenhouse was higher than that in the open field from 6:00 a.m. to 16:00 p.m. in mid-July 1997, from 16:00 in the afternoon to 5:00 a.m. in the middle of July 1997, and lower than that in the open field between 6:00 a.m. and 13:00 p.m. , 13 am to 5 am the next day than the open field. Compared with the open field, the fruit-setting rate increased by 35.2% and the fruit weight increased by 22.1%. The soluble solids in fruit juice increased by 12.7%, the acidity decreased, the fruit quality Obvious improvement.
