Results showed that FM treatment significantly improved the pollen viability especially under FM300 treatment. FM200 and FM300 treatments significantly improved leaf carotenoids, anther size and anther quality of 100 seeds compared with the control. The anther width was significantly increased by 0.13 mm at FM300. However, physiological indexes such as filament length, anther length, pistil development type, hundred leaves length, hundred leaves width, hundred leaves thickness, hundred leaves weight and pollen fullness were not affected by FM. It can be seen that FM had a greater effect on growth and physiology indicators of pearl oil apricot, while the effect on soil physicochemical properties was smaller.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139318232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Components of sludge from municipal wastewater treatment plants and its evaluation for land application in JiUJiang city of China","authors":"Qiyong Yang, Yanbin Zhao, Ji Wang, Han Zhou, Houfeng Xiong, Ming Zeng, Luliu Chen, Nanting Huang","doi":"10.56028/aetr.8.1.367.2023","DOIUrl":"https://doi.org/10.56028/aetr.8.1.367.2023","url":null,"abstract":"Municipal sewage sludge has a potential for widespread application on land, but the implementation of new standards for the agricultural use of sludge in China support a cautious approach. The organic matter, nutrients, and heavy metals in sewage sludge from four municipal wastewater treatment plants in Jiujiang City of China were continuously monitored. The feasibility for its land use was analyzed from three aspects such as sludge nutrients, heavy metal pollution levels, and potential ecological risks in soil. The average content of Cd, Cu, Zn, Cr, Ni, Pb, Hg and As in the sludge of Jiujiang City are 1.85, 305.25, 764.48, 170.57, 42.45, 42.27, 0.59, 28.79 mg∙kg-1, which are less than or close to mean value of heavy metals in China (except As), and all meet the minimum standards of heavy metal content in the sludge according to Chinese Quality of sludge from municipal wastewater treatment plant (GB24188-2009). The maximum content of Cu, Zn, Cr, and As exceed the control standards of pollutants in sludge for agricultural use, and the maximum value of Cu and Cr are close to the limit of landscaping standards. The average contents of organic matter, total nitrogen, total phosphorus, total potassium, and total nutrients in sludge are 385.16, 34.14, 11.05, 7.87, 53.06 g∙kg-1, respectively. The organic matter content meets the limit value (no less than 200 g∙kg-1) of Chinese Control standards of pollutants in sludge for agricultural use (GB 4284-2018), and the total nutrients content meets certain content limit (no less than 40 g∙kg-1) of total nutrients in China’s organic fertilizer. The single-factor pollution index and Nemerow’s synthetic pollution index methods were used to assess the pollution of heavy metals. The heavy metal pollution indexes (PI) are in descending order: Cd > Cu > Zn > Cr > As > Ni > Pb > Hg. The PI shows that Cd and Cu are in strong pollution level, Zn is in moderate pollution level, and As, Ni, Pb, Hg are in absolute safe level. The potential ecological risk levels of heavy metal are ranked in the following order: Cd> Cu> As> Ni> Zn> Cr > Pb. The monomial potential ecological risk coefficients reveal that Cd is in extremely strong ecological risk, Cu is in medium ecological risk and other heavy metals are in slight ecological risk. The results indicate that Cd and Cu are the main contributors to the pollution and potential ecological risks of heavy metals in soil, to which more attention should be paid during sludge disposal. Being rich in organic matter and inorganic plant nutrients，sewage sludge in Jiujiang City may be widely used on soil, but availability of potential toxic metals exceeding the limit value often restricts its uses. Before being harmlessly treated, the sludge in Jiujiang City should not be used on agricultural land and may be applied with highly caution on landscaping and land improvement, but it can be used as cover materials for co-landfilling.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139318125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samples were measured to compare the difference of plant height, stem width, and panicle length, straw biomass, effective panicle, spikelets per panicle, panicle weight, 100 grain weight, and grain yield. The results showed that compared with MTCS, RSSR can increase rice growth indicators and yield indicators, but had no significant difference. Only the panicle weight of RSSR was significantly higher than that of MTCS. Furthermore, the management of RSSR was more convenient, which can save water, herbicide and human labor.

XRD technique investigated the chemical composition of cement crystal phase, and SEM observed the micro-morphology of high temperature cement. Results showed that the loading metakaolin has reduced porosity by 12.86%, air permeability while greatly increased nanopore (＜50nm) by 36.47% and increased nanopore (＜10 nm) by 10.34%. Thus, the cement permeability reduced greatly or its anti-channelling enhanced, that is, such results improved the comprehensive performance of cement slurry. These observations, combined with the previously reported the remarkable enhancement of the MK cement compressive strength, represent a major step toward the development of strength retrogression-resistant material at high temperature.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"53 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139318140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The case results revealed that in case of a high penetration rate of new energy, there will be a gradual weakening in the improvement effect of increasing daily regulated energy storage on new energy consumption and there will be a gradual “saturation” in the utilization rate of new energy accompanied by the increase of energy storage scale. Nonetheless, measures such as the flexible transformation of thermal power and increase of external transmission channels to promote consumption are not related to the “saturation effect”. The conclusion of this article can be as a reference for other countries and regions in the allocation of flexible resources for promoting new energy consumption.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139317953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that with the increase of soil cover thickness, the germination rate of Salvia miltiorrhiza seeds significantly decreased. The thickness of covering soil was  0 cm, the germination of Salvia miltiorrhiza seeds was the best and the germination rate was 42.08%. When the thickness of covering soil was 1.0 cm, the germination rate of Salvia miltiorrhiza seeds significantly decreased, only 2.91%, which was 93.08% lower than the control. The appropriate concentration of seed coating agent can improve the germination rate of Salvia miltiorrhiza seeds. When the soil thickness was 0 cm+1.25 g∙L-1 fludioxonil, the best germination effect of Salvia miltiorrhiza seeds was observed, and the germination rate was 59.17%, which increased 40.61% compared to 0 cm soil alone. The germination rate of Salvia miltiorrhiza seeds treated with 0 cm+2.5 g∙L-1 fludioxonil was only 13.75%, which was 28.33% lower than the germinationg rate with the soil thickness of 0 cm alone. There was no significant difference in the germination rate of Salvia miltiorrhiza seeds treated with 0.05% carbendazim compared with the control group; The germination rate of Salvia miltiorrhiza seeds treated with 0.1% carbendazim was significantly lower than that of the control group covered with 0 cm soil alone. In summary, The best germination level of Salvia miltiorrhiza seed was the cover thickness of 0 cm soil and 1.25 g ∙ L-1 concentration of  fludioxonil, ( 0 cm+1.25 g∙L-1).
