| 摘 要： | 本研究旨在探究寒旱百合种植区地表覆草技术对土壤水热状况、理化性质、百合生长和产量的影响。采用随机区组设计，试验处理为露地（CK）、地表覆草（S）、地膜覆盖（M），3次重复，共计9个处理。结果表明，百合地表覆草技术可以明显改善土壤水热状况，提高土壤理化性质指标含量，增加百合产量。相对于对照露地处理，表层土壤温度和含水量分别增加了18.86%、16.01%，土壤有机质、碱解氮、速效磷、速效钾含量分别提高了75.61%、18.12%，21.04%、10.41%，株高、茎粗、球横径、球纵径、单球重和产量分别增加了8.26%、22.22%、16.55%、23.47%、32.83%、35.07%。综上所述，在寒旱百合种植区，地表覆草技术是一项重要的田间管理措施。

| Abstract: | The aim of this study is to investigate the effects of surface grass covering technology on soil water and heat conditions, physicochemical properties, lily growth, and yield in cold and arid lily planting areas. Using a randomized block design, the experimental treatments were open field (CK), surface grass cover (S), and plastic film cover (M), with 3 replicates for a total of 9 treatments. The results showed that the surface grass covering technology of lilies can significantly improve the soil water and heat conditions, increase the content of soil physical and chemical properties indicators, and increase the yield of lilies. Compared with the control open field treatment, the surface soil temperature and moisture content increased by 18.86% and 16.01%, respectively. The content of soil organic matter, alkaline nitrogen, available phosphorus, and available potassium increased by 75.61%, 18.12%, 21.04%, and 10.41%, respectively. The plant height, stem diameter, ball diameter, ball longitudinal diameter, single ball weight, and yield increased by 8.26%, 22.22%, 16.55%, 23.47%, 32.83%, and 35.07%, respectively. In summary, in cold and arid lily planting areas, surface grass covering technology is an important field management measure. |
