【摘要】：林參復(fù)合經(jīng)營(yíng)是遼東山區(qū)典型的林下經(jīng)濟(jì)模式之一,而林下參的生長(zhǎng)對(duì)于環(huán)境條件要求很高,其中,土壤質(zhì)量是制約人參生長(zhǎng)的重要因素之一,并對(duì)人參產(chǎn)業(yè)的健康發(fā)展至關(guān)重要。目前,闊葉混交林、針闊混交林和蒙古櫟純林是遼東山區(qū)廣泛分布的林參復(fù)合經(jīng)營(yíng)林分類型,選擇3種林分下立地特征相似、人參種植年限不同的樣地,測(cè)定土壤物理、化學(xué)和生物學(xué)因子共25項(xiàng)指標(biāo),采用方差分析、主成分分析、相關(guān)分析等統(tǒng)計(jì)學(xué)方法和專家經(jīng)驗(yàn)法構(gòu)建了林參復(fù)合經(jīng)營(yíng)土壤質(zhì)量評(píng)價(jià)最小數(shù)據(jù)集(MDS),并利用模糊數(shù)學(xué)法對(duì)不同樣地土壤質(zhì)量進(jìn)行了定量評(píng)價(jià)。結(jié)果表明,研究區(qū)林參復(fù)合經(jīng)營(yíng)土壤質(zhì)量評(píng)價(jià)最小數(shù)據(jù)集包括容重、pH、有機(jī)質(zhì)、速效K、全Zn、微生物量N、酸性磷酸酶和細(xì)菌共8項(xiàng)指標(biāo)。此外,土壤質(zhì)量值由高到低依次為針闊混交林對(duì)照樣地(0.764)蒙古櫟純林對(duì)照樣地(0.745)針闊混交林14a人參樣地(0.614)蒙古櫟純林20a人參樣地(0.385)闊葉混交林12a人參樣地(0.361)闊葉混交林對(duì)照樣地(0.354)闊葉混交林6a人參樣地(0.323)闊葉混交林9a人參樣地(0.308)闊葉混交林3a人參樣地(0.230),說(shuō)明林分類型特征和人參種植年限對(duì)土壤質(zhì)量會(huì)產(chǎn)生不同程度影響。今后,在遼東山區(qū)林參復(fù)合經(jīng)營(yíng)發(fā)展過(guò)程中,可以該最小數(shù)據(jù)集為基礎(chǔ),充分考慮土壤質(zhì)量狀況,并適當(dāng)進(jìn)行管理,以保障人參健康生長(zhǎng),促進(jìn)人參產(chǎn)業(yè)可持續(xù)發(fā)展。
[Abstract]:The compound management of forest ginseng is one of the typical understory economic models in the mountainous area of Liaodong, and the growth of the forest ginseng requires very high environmental conditions, among which, the soil quality is one of the important factors restricting the growth of ginseng. At present, broad-leaved mixed forest, coniferous and broad-leaved mixed forest and pure Quercus mongolica forest are widely distributed in the mountain area of Liaodong. In this paper, 25 soil physical, chemical and biological factors were measured in three stands with similar site characteristics and different planting years of ginseng. The variance analysis and principal component analysis were used to analyze the soil physical, chemical and biological factors. Correlation analysis and other statistical methods and expert experience method were used to construct the minimum data set of soil quality evaluation of forest ginseng compound management (MDS). The results showed that the minimum data set of soil quality evaluation of forest ginseng compound management in the study area included pH of bulk density organic matter available K and total Zn. Microbial biomass N, acid phosphatase and bacteria a total of 8 indicators. Soil quality value from high to low was 0.764 for coniferous and broad-leaved mixed forest, 0.745 for pure Quercus mongolica forest and 0.745 for coniferous and broad-leaved mixed forest, and 0.614 for coniferous and broad-leaved mixed forest. Quercus mongolica pure forest 20 a ginseng sample land 0.385) broad-leaved mixed forest 12a ginseng sample land 0.361) broad-leaved mixed forest 0. 354) broad-leaved mixed forest 6a ginseng sample land (. 0.323) 9a ginseng sample plot 0.308) broad-leaved mixed forest 3a ginseng sample plot 0.230). It is concluded that the characteristics of stand types and the planting years of ginseng have different effects on soil quality. In the future, the minimum data set can be used as the basis in the process of compound management and development of forest cucumber in the mountainous area of Liaodong. In order to ensure the healthy growth of ginseng and promote the sustainable development of ginseng industry, the soil quality should be considered and managed properly.
