Identification of Dominant Microbial Communities on the Foliage of Zimbabwean Tobacco Using a Novel Tobacco-containing Medium
QIU Yan-ling;ZHOU Rong;ZHU Xin-quan;In order to better identify the dominant microorganisms on the leaves of Zimbabwean tobacco, tobacco components at concentrations(volume fractions) of 0%,2.5%,5.0% and 10.0% were added to simulate the microbial growth environment on the surface of tobacco leaves, to screen the concentration of tobacco leaves suitable for microbial growth, to explore suitable tobacco culture medium preparation conditions, to analyze the differences in the composition of the microbial communities of tobacco leaves at different concentrations, to isolate and identify specific microorganisms.The results showed that more specific microbial communities could be isolated when the tobacco leaf culture medium was adjusted to pH 7.0 at concentrations of 2.5% and 5.0% after sterilization.Metagenomic sequencing technology was used to determine the community distribution of microorganisms on the surface of tobacco leaves in Zimbabwe.It was found that Bacillus had a high relative abundance in the culture medium at concentrations of 0%,2.5% and 5.0%,and after the addition of tobacco to the culture medium, Terribacillus became the dominant species.The genera with higher relative abundance on tobacco culture medium at concentrations of 2.5% and 5.0% included Piscibacillus,Amphibacillus,Margalitia,etc.Through isolation and sequencing, 15 kinds of dominant microorganisms on the surface of tobacco leaves were identified, such as Bacillus species of the genus Bacillus,Bacillus veleis and Bacillus subtilis.
Research Progress on Land Suitability Evaluation
OUYANG Shi-juan;LUO Ye;JIANG Guo-liang;Land suitability refers to the suitability of a particular type of land for a particular use. Global population growth and environmental problems pose serious challenges to land security. Currently, the uneven distribution of land resources in China affects agricultural production decisions and jeopardizes national food security and sustainable development. Land suitability evaluation is the key to ensuring the rational planning and utilization of land resources, which is of great significance in optimizing land production potential, alleviating human-land conflicts and achieving land sustainability. This paper systematically reviews research progress of land suitability evaluation on the connotation, spatial scale, indicator systems, methods and ideas by the literature review method, and points out its shortcomings and the direction of future research, with a view to providing reference for optimizing the structure of land resource utilization and achieving sustainable development goals. Future research should follow a path that includes learning from the theories of geography, ecology, economics and other disciplines to strengthen the basic theoretical research, focusing on ecological orientation, improving evaluation indicators, expanding application space of the research results, and innovating evaluation methods and models, etc.
Analysis of Yield Difference of Different Sesame Types at Different Harvest Periods
WEI Song-shan;WU He-min;LIU Mei-ru;In order to clarify the difference of yield reduction causes of different sesame varieties after maturity.In this paper, we took four sesame varieties(three conventional varieties, one non-shattering variety) as experimental material to study.The sesames were harvested in four stages(not open, just open, half open, full open) according to the degree of capsule dehiscent after maturity.We compared and analyzed the yield traits of these two types of sesame at different harvest periods.The results showed that the seeds per capsule, 1 000-seed weight and the seed yield per plant of three conventional sesame varieties decreased significantly with the increase of the capsule dehiscent degree.1 000-seed weight were the seed yield per plant of non-shattering sesame variety decreased significantly with the increase of capsule dehiscent degree.The results showed that the seeds per capsule and 1 000-seed weight were significantly and positively correlated with the seed yield per plant of three conventional varieties, therefore the seeds per capsule and 1 000-seed weight were the main factors that caused the decrease of the seed yield per plant of conventional variety.There was a significantly positive correlation between 1 000-seed weight and the seed yield per plant of non-shattering variety, so 1 000-seed weight was the main factor that caused the decrease of the seed yield per plant of non-shattering variety.
