RESUMO
Arbuscular mycorrhizal fungi provided is beneficial to Salvia miltiorrhiza for increasing yield, promoting the accumulation of active ingredients, and alleviating S. miltiorrhiza disease etc. However, the application of fungicides will affect the benefit of arbuscular mycorrhizal fungi and there is little research about it. This article study the effect of four different fungicides: carbendazim, polyoxin, methyl mopazine, and mancozeb on mycorrhiza benefit to S. miltiorrhiza by the infection intensity of arbuscular mycorrhizal fungi, the growth of S. miltiorrhiza, and the content of active ingredients. RESULTS:: showed that different fungicides had different effects. The application of mancozeb had the strongest inhibitory effect on the mycorrhizal benefit to S. miltiorrhiza. Mancozeb significantly reduced the mycorrhizal colonization and the beneficial effect of arbuscular mycorrhizal fungi on the growth and the accumulation of active components of S. miltiorrhiza. The application of polyoxin had no significant effect on mycorrhizal colonization. Instead, it had a synergistic effect with the mycorrhizal benefit to promoting the growth and accumulation of rosmarinic acid of S. miltiorrhiza. The inhibitory strengths of four fungicides are: mancozeb>thiophanate methyl, carbendazim>polyoxin. Therefore, we recommend applying biological fungicides polyoxin and avoid applying chemical fungicides mancozeb for disease control during mycorrhizal cultivation of S. miltiorrhiza.

By comparing the effects of soil pH on the efficiency of mycorrhizal symbiosis on Salvia miltiorrhizaï¼ the study is aimed to provide guidance for the use of mycorrhiza in the cultivation of S. miltiorrhiza. In this experiment, the inoculant treated and the non-inoculant treated control were grown in different soil pH. The data was collected after 60 days of cultivation including rate of mycorrhizal infection, biomass, and three chemical constituents with known medicinal action. The results showed that Glomus versiforme was more apt to infect S. miltiorrhiza (F>94.00%; M>69.45%; m>73.66%) and promote the growth of S. miltiorrhiza under pH 5-9 soil. The mycorrhizal contribution to the growth of S. miltiorrhiza was the highest when grown in pH 8 soil. Plants grown with mycorrhiza in pH 8 soil had above-ground biomass more than 2 times and root biomass more than 5 times. The uninoculated plants grew better under acidic and neutral conditions, but the inoculated plants grew better under alkaline (pH 8) conditions. This result showed mycorrhiza can play a role in the adaptability of S. miltiorrhiza to the environment. Inoculation of mycorrhiza significantly increased the accumulation of rosmarinic acid, salvianolic acid B, and dihydrotanshinone by 6.59,5.03 and 2.20-folds. Based on our results alkaline soil (pH 8) is most suitable for the cultivation of S. miltiorrhiza by inoculation with the mycorrhiza G. versiforme.

Lepidium meyeniiï¼macaï¼was a herbaceous plant of the family Cruciferae. It is native to the andes region of South America where the local people had been growing and consuming maca for centuries. The unique chemical composition and physiological function of maca were widely concerned worldwide. It was introduced to China in 2002, and were cultivated successfully in Yunnan, Tibet, Sichuan, Jilin and other places with a certain size. Maca contained not only rich nutrition such as protein, vitamin and mineral matter, but also lots of secondary metabolites as maca alkaloids, glucosinolates, volatile oils, sterols polyphenols and macaenes. Numerous studies suggested that maca may serve effects in resisting oxidation, fatigue resistance, raising fertility, regulating endocrine, enhancing immunity, tumour suppression, treating osteoporosis, regulate blood sugar and protection of nervous system. Maca was approved by the Ministry of Health as a new resource food in 2011, and its related products include food, health foods, cosmetics, etc. Certain exploratory researches were carried to take better advantage of maca's medicinal value. This paper briefly reviewed the research and application progress of maca in recent years from the aspects of botany, chemical composition, function, resources situation and related products development, which was supposed to provide reference for scientific research and utilization of maca.

Traditional Chinese medicine industry product a lot of herb residue. Herb residue was treated as household waste. This treatment leads to environmental pollution and resource waste. For this case, we study the effect of different herb residues on the growth and active ingredient content of Licorice by random control experiment. Our results showed that the effects of different herb residues were difference. Atractylodes macrocephala residue and Forsythia suspense residue had the stronger effect and the effect of A. macrocephala residue was inferior to the effect of F. suspense residue. A.macrocephala residue significantly improved the shoot biomass banch number, leaf number, root diameter and root biomass by 0.53-1.81 fold. A. macrocephala residue also increased the glycyrrhizic acid content of root by 1.54 fold. F. suspense residue significantly improved the shoot biomass,branch number, root diameter and root biomass by 0.43-1.13 fold. Four kind herb residues all improved the shoot biomass by 0.43-1.81fold. So, the authors recommand to considered that we can apply A. macrocephala residue and F. suspense residue in Licorice cultivation.

Herb residue is post-decoction material that can be used as organic fertilizer. Unfortunately, it is currently disposed of as solid waste. This method of disposal is a waste of this resource and a source of environmental pollution. For this case,we studied effects of six different herb residues compost on growth and phenols of Perilla frutescens by pot experiment. Our results show that all six herb residues can improve the growth of P. frutescens. The order of their efficiencies was as followsï¼ Salviae Miltiorrhizae Radix residue>Hordei Fructus germinates residue>Forsythia fructus residue>Atractylodis Macrocephalae Rhizome residueï¼Sophorae Flavescentis Redix residue and Moutan cortex residue. Effects of Sophorae Flavescentis Radix residue and Moutan Cortex residue weren't significantly different from CK. Six herb residue all improve root system architecture and leaf area. To phenols of P. frutescens, six herb residues all increased the rosmarinic acid and caffeic acid content of root, and accumulation of four phenols. All the analysis showed herb residues compost can improve the growth and four phenols accumulation of P. frutescens, and Salviae Miltiorrhizae Radix residue had the most pronounced effect on P. frutescens.

In order to obtain the fungicides with minimal impact on efficiency of mycorrhizal symbiosis, the effect of five fungicides including polyoxins, jinggangmycins, thiophanate methylate, chlorothalonil and carbendazim on the growth of medicinal plant and efficiency of mycorrhizal symbiosis were studied. Pot cultured Glycyrrhiza uralensis was treated with different fungicides with the concentration that commonly used in the field. 60 d after treated with fungicides, infection rate, infection density, biomass indexes, photosyn- thetic index and the content of active component were measured. Experimental results showed that carbendazim had the strongest inhibition on mycorrhizal symbiosis effect. Carbendazim significantly inhibited the mycorrhizal infection rate, significantly suppressed the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. Polyoxins showed the lowest inhibiting affection. Polyoxins had no significant effect on mycorrhizal infection rate, the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. The other three fungicides also had an inhibitory effect on efficiency of mycorrhizal symbiosis, and the inhibition degrees were all between polyoxins's and carbendazim's. The author considered that fungicide's inhibition degree on mycorrhizal effect might be related with the species of fungicides, so the author suggested that the farmer should try to choose bio-fungicides like polyoxins.
