Zhonghuang 35 with low salt tolerance and Zheng 1311 with high salt tolerance were selected respectively, and NaCl solutions with concentrations of 0.250, 0.250, 0.125, 0.0625 and 0 mol L-1 were set for hydroponics, the effect of NaCl concentration on soybean germination was determined by variance analysis. The results showed that the concentration of NaCl was significantly correlated with the germination rate of Zhonghuang 35 and Zheng 1311 soybean varieties. The health of soybean is inversely proportional to NaCl concentration. The effect of NaCl concentration on germination in Zhonghuang 35 was more obvious than that in Zheng 1311. This study provides a theoretical basis for soybean growth in saline-alkali soil.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"37 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139271305","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}

Influence law of wheat straw on performance of cement insulation mortar was discussed. Influence factors included pretreatment method, dosage and length of straw. Features of straw surface pretreated by NaOH solution and bonding interface were observed by scanning electron microscopy. Dry density, compressive strength, thermal conductivity coefficient reduce with the increase of straw length and the decrease of soak time. When straw dosage increases, they decrease firstly, increase later. Straw reduces the mass loss of cement insulation mortar treated at temperature below 500℃. Straw surface pretreated by NaOH solution becomes rough. There are trenches with widths about a few microns. It makes a better interface combination between straw and cement matrix.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"108 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139315916","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}
