日光温室是以塑料薄膜为透明覆盖材料、以太阳能为主要热源的保护地栽培形式,在我国北方地区规模很大,是解决人们冬春季节蔬菜需求的主要途径。日光温室内的小气候特点从总体上可以概括为昼夜温差大、湿度高、光照强度分布不均匀。如何有效地利用好日光温室内的各种小气候条件,使其在不增加投资的情况下,可以提高蔬菜的产量 Solar greenhouse is a transparent plastic cover material, with solar energy as the main source of protected cultivated forms in northern China is very large, is to solve people’s winter and spring vegetables the main way demand. Microclimate characteristics of sunlight greenhouse can be summarized as a large temperature difference between day and night, high humidity, uneven distribution of light intensity. How to make good use of various microclimate conditions in solar greenhouse so that it can increase the yield of vegetables without increasing the investment
