日光温室最常用的外覆盖材料是蒲席和草苫，其保温性能好，但笨重，易污染，易损坏薄膜，浸水易腐烂，所以需要更新。本研究的目的是选出１种～２种日光温室新型保温外覆盖材料，其保温性能接近于草苫，质地轻、不易浸水、寿命长、价格合理。一、室内实验筛选阶段首先经严... The most commonly used outer cover materials in solar greenhouses are cotton and straw, which have good thermal insulation properties, but they are bulky, easily contaminated, easily damaged by membranes, and immersed in perishable water. Therefore, they need to be updated. The purpose of this study is to select one or two kinds of new types of insulation materials for solar greenhouses. The insulation properties of the materials are close to those of grasshoppers, and they are light in texture, difficult to inundate, have a long life, and are reasonably priced. First, the indoor experiment screening stage first strictly...
