日光温室以其结构简单，造价低廉，节省能源，效益可观等优点而迅猛发展。但日光温室存在着一个普遍的缺点，就是气温高而地温低，并且越是寒冷的时期表现越突出，这样就大大的限制了根系生长，使作物头重脚轻而长期处于病态生长。在实践中我们探索应用了太阳能暖沟回流阳... Solar greenhouse with its simple structure, low cost, energy saving, considerable benefits and other advantages of the rapid development. However, there are common shortcomings of solar greenhouse, that is, the high temperature and low temperature, and the more prominent the performance of the more cold period, thus greatly limiting the root growth, crop weight-bearing and long-term in a pathological growth. In practice, we explore the application of solar warm ditch back to the sun ...
