摘要
以里格尔87-5番茄为材料,研究了膜下滴灌与沟灌两种方式的田间小气候特征,结果表明:滴灌番茄生育前期提高土壤温度,旺盛生育期有降温效应,保持土壤湿度,防止灌溉水渗漏,光照强度和光合速率优于沟灌,明显改善了番茄生育期的生态小气候条件。
The experiment was conducted in two different irrigation patterns （drip irrigation under membranes and furrow irrigation） with Liger87-5 tomato. The results showed ：drip irrigation under membranes could obviously raise soil temperature in earlier growing stage, drop soil temperature during healthy growth stage, keep soil humidity, prevent irrigative water leakage, illumination intensity and photosynthesis exceeded furrow irrigation. In addition, drip irrigation under membranes could remarkably improve eco-microclimatical condition in tomato growing period.
