    摘要:

    以河北壩上地區(qū)羊草草地為研究對(duì)象，采用野外取樣與實(shí)驗(yàn)室分析相結(jié)合的方法研究了原地放垡振動(dòng)間隔松土對(duì)羊草草地的影響,。結(jié)果表明,，羊草草地經(jīng)過原地放垡振動(dòng)間隔松土處理后,，土壤容積密度降低,、毛管持水力升高和土壤含水率增加,，同時(shí)土壤養(yǎng)分也呈現(xiàn)不同程度的優(yōu)化,；植物高度,、蓋度,、密度和地上,、地下生產(chǎn)力提高，優(yōu)良牧草所占的比例有所增加，草地群落的植物多樣性得到提高,；在草地處理3年內(nèi)平均每公頃每年增加收入

    Abstract:

    155元,。Based on zone tillage theory, a paired-site design was adopted to qualitatively and quantitatively evaluate the effect of situ-vibration tillage on Leymus chinensis grassland, which would be applied to provide theoretical reference and technical support for restoring degraded Leymus chinensis grassland. Results showed that the soil bulk density decreased, soil water holding capacity and water content increased and the content of soil nutrient increase to some extent after the grassland scarified; the height, cover, density of grass vegetation, above and below-ground yield, proportion of excellent and good forges and grassland plant diversity all increased, the yearly average economic benefit from the grassland soil scarifying was 155 RMB/hm2 in next 3 year.
