寒地水稻井水增温技术研究

摘要

Test of increasing well water temperature with coverage showed that covering material and covering method had a significant impact on water temperature. Transparency of suspension membrane was positively correlated with water temperature, but it performance not obvious on pastes membrane, so it should use suspension membrane which had high transmittance on heightening well water temperature.%通过水体覆盖试验研究，结果表明：覆盖材料及覆盖方法对水体增温都有显著影响。采用悬膜覆盖水体增温悬膜的透光率，同水体增温变化呈正相关。而在贴膜覆盖中表现不明显，因此在生产上应采用透光率高的密闭材料悬膜覆盖对井水增温。
