中文摘要	在宁南山区海原县关庄乡高台村试验田,采用膜下滴灌节水技术,研究了覆膜不滴灌、滴灌不覆膜、膜下滴灌和不滴灌不覆膜(CK) 4种方式下马铃薯生育期的土壤养分、酶活性以及马铃薯产量的差异。结果表明:在0~20 cm和20~40 cm土层中,膜下滴灌种植条件下,与CK相比较,有机质含量分别提高了3.88%、18.23%,碱解氮提高了10.71%、18.75%,速效钾提高了 5.92%、2.55%,生育期内土壤脲酶活性提高了27.05%~ 69.37%、0.17%~ 38.33%,碱性磷酸酶活性提高了12.70%~23.90%、6.99%~28.93%,转化酶活性提高了5.65%~ 68.12%、8.41%~ 31.63%,纤维素酶活性提高了8.33%~32.94%、19.98%~108.82%,产量提高了107.90%;土壤养分与酶活性及马铃薯产量间存在显著正相关。研究得出,膜下滴灌可以改善土壤微生态环境,提高土壤酶活性,改善土壤养分循环能力,增加产量,是干旱半干区马铃薯旱作节水栽培的有效措施之一。
英文摘要	In order to explore the most suitable potato planting method in the arid and semi-arid areas of southern Ningxia,this experiment used the experimental field of Gaotai Village,Guanzhuang Township,Haiyuan County,Southern Ningxia Mountain,using drip irrigation,and water-saving technology under the film,and studied four cropping methods including mulch without drip irrigation and drip irrigation without mulching,drip irrigation under mulch,and no drip irrigation or mulching (CK) on the growth characteristics of soil nutrients,enzyme activity,and potato yield of potato during the growth period.The results showed that:in the 0 ~ 20 cm and 20 ~ 40 cm soil layers,drip irrigation under mulch,compared with no drip irrigation or mulching (CK),the organic matter content increased by 3.88% and 18.23%,respectively,and alkali-decomposed nitrogen increased by 10.71%,18.75%,the available potassium increased by 5.92% and 2.55%;soil urease activity increased by 27.05% to 69.37%,0.17% to 38.33% during the growth period;alkaline phosphatase activity increased by 12.70% to 23.90%,6.99% to 28.93% during the growth period;Invertase activity increased by 5.65%~68.12%,8.41%~31.63% during the growth period;Cellulase activity increased by 8.33% ~ 32.94%,19.98% ~ 108.82% during the growth period;Yield increased by 107.90%;There was a significant positive correlation between soil nutrients and enzyme activity and potato yield.Drip irrigation under mulch improved soil micro-ecological environment,increased soil enzyme activity,improved soil nutrient cycling ability,and increased yield.It was one of the effective measures for potato water-saving cultivation in arid and semi-dry areas.
