Study on artificial cultivation of moss crust in Horqin sandy land
摘要
Abstract
[Objective]The purpose of the study is to explore the key influencing factors and optimal combina-tions of moss crust in Horqin sandy land,and to provide theoretical support for ecological restoration of large-scale crust crust in this area.[Method]Through orthogonal experiment design,considering 6 factors,such as inoculation amount,litter species,sandy soil amount,water addition interval,light transmittance and planting addition method,the response of moss crust coverage,plant height and dry weight to different factors was analyzed.[Result]1)Inocula-tion amount,litter species,sandy soil amount,water addition interval,light transmittance and planting method had sig-nificant effects on the cover,plant height and dry weight of moss crust(P<0.05),and different factors had different effects on each index.2)In terms of coverage,the maximum was 96%under the conditions of inoculation amount of 150 g,organic fertilizer 15 g,sandy soil 250 g,water addition interval of 5 days,light transmittance of 70%,and plant-ing addition method(upper seed soil in the middle of litter and lower sandy soil).Under the conditions of inoculation amount of 90 g,organic fertilizer 15 g,sandy soil 0 g,water addition interval of 5 days,light transmission of 70%,planting addition method(between the upper seed soil and the litter of the lower sandy soil),the maximum was 3.38 mm.In terms of dry weight of the layer,The maximum inoculation amount of 150 g,biochar 15 g,sandy soil 100 g,water addition interval of 5 days,light transmission of 40%,and planting addition method(mixed addition)condition was 0.69 g/cm2,which was significantly higher than that of other treatments.[Conclusion]Because the coverage could directly reflect the growth status of moss crust,the optimal combination for rapid cultivation of moss crust in Horqin sandy land was 150 g inoculation amount,15 g organic fertilizer,250 g sandy soil,5 d water addition interval,light transmittance of 70%,upper seed soil,middle litter and lower sandy soil,and 50 d greenhouse cultivation,the coverage of moss crust could reach 85%.关键词
