不同灌溉方式对土壤质量的影响

Effects of Different Irrigation Methods on Soil Quality

为研究不同灌溉方式下对土壤质量的影响,试验设计全膜平作畦灌(FB)、全膜双垄沟灌(FI)和全膜膜下滴灌(FD)三种方式,研究了土壤温度、水分和养分的变化特征,结果表明,不同灌溉方式对土壤影响不同,和全膜平作畦灌、全膜膜下滴灌相比,全膜双垄沟灌方式能够增加土壤温度和含水量,提高土壤速效磷和速效钾含量,而做生长受到土壤水热和养分的影响较大,因此,全膜双垄沟灌方式具有较大的优势。

In order to study the effects of different irrigation methods on soil quality,three methods were designed to study the changes of soil temperature,moisture and nutrient.The results showed that different irrigation methods had different effects on soil.Compared with the different irrigation methods in border irrigation and drip irrigation under film film,full-film double-ridge irrigation can increase soil temperature and water content,and increase soil available phosphorus and available potassium content.However,soil growth is greatly affected by soil water,heat and nutrients.Therefore,full-film double-ridge irrigation has greater advantages.
