2种防雨棚对空气温湿度及周年蔬菜生长的影响
Effects of Air Temperature/Humidity and Vegetable Growth Under 2 Types of Rain Proof Cover
摘要
Abstract
The effects of temperature,humidity as well as vegetable growth under 2 types of rain proof cover annually were studied.Cropping twice with Chinese flowering cabbage and then tomato/pepper under three treatments rain proof cover with empty around (RPC),insect proof net around (RPC+IPN),the outside,at the same time monitor temperature and humidity was used.The results showed that temperature in RPC and RPC+IPN was higher than the outside in the daytime yearly,but differences less than 3 ℃.The average relative humidity of RPC was the highest,while the RPC+IPN was close or lower to outside in the daytime yearly.The length ratio of relative humidity among 40%-80% under the three treatments was 50.4% (RPC),38.6% (RPC+IPN),43.3% (outside),respectively.RPC significantly increased Chinese flowering cabbage yield (by 33.0%-57.5%),as well decreased insects.RPC+IPN increased Chinese flowering cabbage yield without significant difference to RPC and the outside.The insect proof of RPC+IPN was outstanding,the insect leaves rate was lower than 7% and the pest index was lower than 2.Tomato death seedling rate of RPC and RPC+IPN decreased 64%,tomato yield increased by 3 times and pepper yield nearly doubled.The temperature and relative humidity fit for vegetable growth in south China,and the vegetable rotation pattern in the experiment is suitable to promote in RPC and RPC+IPN.关键词
