Glycyrrhiza inflata Bat. is a leguminosae belonging to the genus Glycyrrhiza medicinal plants, licorice have a longer growth cycle, it needs to grow three to five years before they can sell, on cash flow growers difficult, therefore, how to make more economic benefits before the first or two years of licorice is a key. According to local market demand, this study used interplanting technique between Glycyrrhiza inflata and Cucumis melo var. Saccharinus, jiashi muskmelon to study the influenceunder intercropping patterns about soil physical and chemical properties, soil enzyme activity, soil microbial quantity in their yield and quality of soil microbial community diversity. In order to improve the economic efficiency of the farmers, at the same time, In addition to provide a scientific basis for the ecological restoration. The results are as follows:1. Effects of the interplanting between Glycyrrhiza inflata and Cucumis melo var. Saccharinus, jiashi muskmelon on soil physical and chemical properties, affecting the activity, microbes and microbial community functional diversity.Planting glycyrrhiza inflata and Cucumis melo var. Saccharinus, jiashi muskmelon can improve the physical and chemical properties of soil.Compared with the Cucumis melo var. Saccharinus, jiashi muskmelon plots which was be monocultured,The interplanting between glycyrrhiza inflata and Cucumis melo var. Saccharinus, jiashi muskmelon increased soil total nitrogen, total phosphorus, nitrogen, phosphorus, organic matter content.In three consecutive years of growth process, plots interplanted increased soil total nitrogen, nitrogen, potassium, organic matter content compared with monoculture plots;The p H value and conductivity of the soil which been monocultured and interplanted plots are declining, soil moisture upward trend with the increasing expansion of cropping years locorice, in which the soil water content in 3-year-old licorice interplanted plots highest than 3 years old licorice monoculture plots improved 31%(P<0.05).Different treatment about the plots improved the activity of soil urease, phosphatase, sucrase, cellulase and catalase enzyme.The enzyme activities between Jiashi melon interplanted plots and monoculture plots have a little difference;Interplanting plots soil urease, phosphatase, invertase and catalase activity in varying degrees of increase,compared with monoculture plots licorice.Interplanting increased the number of soil bacteria, fungi and actinomycetes, and the number of fungus on the rise,with the increasing planting years.Interplanting affected the soil microbial community functional diversity, The 1-year-old and 2-year-old plots which was been interplanted by Cucumis melo var. Saccharinus, jiashi muskmelon, their AWCD, Shannon-Wiener diversity index, Simpson dominance index and carbon as source richness index were significantly higher in monoculture plots licorice(P <0.05). Principal component analysis show:The main cause of soil microbial carbon utilization differences are sugars, amino acids and Carboloy acids.2.Correlation between soil physical and chemical analysis, enzyme activity and the number of microorganisms and the stepwise regression analysis.The results showed that: The enzyme activity,total nitrogen, nitrogen, organic matter and moisture in soil have a good correlation, the correlation coefficient between 0.503-0.932, beside these they also have a significant level(P <0.01); the relationship between micro-organisms and total nitrogen, nitrogen, water content in soil has a significantly positively correlated(P <0.01), the relationship between micro-organisms and their total phosphorus showed a significant positive correlation(P <0.05); The urease, phosphatase, invertase have a good correlation with their microbial in soil.By stepwise regression analysis, The increasing of nitrogen,organic matter content of nutrients in soil can improve the enzyme activity in soil; Using microorganisms and organic matter, conductivity, total potassium, total nitrogen, nitrogen, and other physical and chemical factors member in soil regression equation, consistent with the results of simple correlation analysis.3. The interplanting between Glycyrrhiza inflata and Cucumis melo var. Saccharinus, jiashi muskmelon on crop yield and qualityThe interplanting between Glycyrrhiza inflata and Cucumis melo var. Saccharinus, jiashi muskmelon can improve the quality of Cucumis melo var. Saccharinus, jiashi muskmelon, The fruit weight, flesh thickness and water content improved 48.8%, 7.6% and 3.5% between the Cucumis melo var. Saccharinus, jiashi muskmelon which was been interplanted, and their soluble solids, organic acids and soluble sugar content increased by 3.1%, 15.9% and 1.3%; compared with the monoculture plots, The glycyrrhiza inflata in the interplanting plots have a small change about their acid content, and their total flavonoid content was increased.In summary, throughthe interplanting glycyrrhizainflata and Cucumis melo var. Saccharinus, jiashi muskmelon not only improved the physical and chemical properties of soil, but also improved the microbial enzyme activity and quantity in soil, future more the interplanting conducived to expansionglycyrrhizainflata and Cucumis melo var. Saccharinus, jiashi muskmelon quality improvement. It also has a greatly improving of the value by planting licorice, increased the enthusiasm of farmers plantinglocorice.
