Biomass Energy Group Report in August 2019
Place: Room 318, 3rd Floor, School of Energy and Environmental Science, Yunnan Normal University
Meeting time: 9:00 to 17:45 , August 24th, 2019 (Saturday)

Host: Zhanyao Zheng
Report 1. Experimental Study on Different Additives of Anaerobic Dry Fermentation
Speaker: Zhen Zhang
Zhen Zhang reported in detail on the experimental results of different assistants for dry anaerobic fermentation. During the discussion, the concept of anaerobic dry fermentation was questioned, and it was suggested that high concentration fermentation be more suitable. For the classification of additives, it was necessary to verify that the types of additives were dispersed and lack of pertinence. It was suggested that the types of additives should be classified reasonably and their effects on acidification should be studied. It was suggested that the gas production rate of fresh cow manure fermentation after adding additives should be compared with that of fermentation without additives and analyzed with the literature. It was also pointed out that VFAs was more conducive to methane production in biogas fermentation.
Report 2. Study on Technical Feasibility and Extension Strategy of Vegetable Planting with Biogas Fertilizer in Qujing City
Speaker: Jiaolin Li
Jiaolin Li reported on the effect of hot water pretreatment on the biogas production of Eupatorium adenophorum Spreng. During the discussion, Questions were raised about the specific treatment methods of the experiment, and the specific reasons for the influence of hot water immersion on gas production of Eupatorium adenophorum Spreng were speculated. Hot water treatment may lead to changes in some components of Eupatorium adenophorum Spreng and then affect gas production. The Latin name of Eupatorium adenophorum Spreng should be correctly written and the relevant literature should be read in depth and carefully.
Report 3. Exploration on the Construction of Circulating Agricultural Model of Combination of Planting and Nurturing-Taking Mountain Village of Qujiang as An Example
Speaker : Li Song
First of all, Li Song reported on the feasibility of vegetable planting technology with Biogas Manure in Qujing City and the contents of promotion strategies. During the discussion, it is proposed that the number of words should be simplified in the ppt, and the text should be as good as possible. The form should adopt the proposal of three-line format. It is necessary to further consider the proportion of bio-fertilizer instead of chemical fertilizers. It is recommended to further analyze the different substitution ratios when calculating economic benefits. The economic benefits; it is suggested that when expounding the feasibility, the soil quality of the biogas fertilizer should be discussed first to affect the quality of the vegetables. The paper should increase the vegetable planting situation in the county. The literature review should supplement the varieties of the biogas fertilizer planting and analyze the application effects.

It is recommended to deeply explore local cultural legends and special festival forms before the construction of the model; The current centralized farming is more centralized management, the status quo of small-scale farming is gradually banned, and the development of the breeding industry should focus on brand building; it is necessary to increase the description of geological landforms in describing the general situation of geography and River trends and local Party construction, and to actively play the role of Party members in the construction of the local beautiful rural model.
Report 7. Study on Gas Production Potential of Gerbera jamesonii by Anaerobic Fermentation
Speaker: Guang Yang
Guang Yang mainly reported on the experimental contents of exploring the biogas potential of Gerbera jamesonii. In the discussion, some suggestions were put forward for the experimental results. The analysis of the low methane content in the experimental process and the lack of scientific results suggested that further experiments should be carried out.
