大棚小气候特征及其对大樱桃生长的影响

摘要

2012年在山东省临朐县开展了大棚种植大樱桃和露天栽培大樱桃观测试验，分析大棚内小气候特征及其对大樱桃生长发育的影响。结果表明，在观测期内，大棚内日平均气温、最高气温、最低气温、相对湿度均较棚外高；大棚内最高气温和最小相对湿度均出现在午后时段，最低气温和最大相对湿度一般都出现在早晨；棚内气温、相对湿度的日较差晴天时最大，阴天时最小。大棚内大樱桃开花期与成熟期均提早，使得大樱桃生长发育避开不利天气影响，增加产量。%The observation trials of sweet cherry in greenhouse and outdoor were carried out in Linqu County of Shandong Province in 2012.The characteristics of microclimate in greenhouse and their effects on growth and development of sweet cherry were analyzed.The results showed that during the observation period, the daily average temperature,maximum temperature,minimum temperature and relative humidity in green-house were all higher than those of outside.The highest value of air temperature and the minimum value of rel-ative humidity in greenhouse appeared in the afternoon,while the minimum air temperature and the maximum relative humidity generally appeared in the morning.The daily range of air temperature and relative humidity in greenhouse was maximum in sunny days,but minimum in overcast days.The blossom and mature stage of sweet cherry were earlier in greenhouse,which made the growth of sweet cherry avoid adverse weather to in-crease production.
