Using Yunyan 87 as the test material, the “3414” field experiment design was used to analyze the agronomic characters, chemical components and economic indicators of flue-cured tobacco, and the NPK fertilizer rate was fitted by the fertilizer effect function equation. The agronomic characters and chemical components of different treatments are quite different. Comprehensively analyzing the growth and development of flue-cured tobacco and the performance at maturity, as well as the analysis of improving the yield and economic benefits of flue-cured tobacco in the later period, the effect of treatment T5 is the best. The established equation model can predict that the maximum fertilizer rates of N, P and K are 12.83 kg/666.67m 2 , 35 kg/666.67m 2 and 34.04 kg/666.67m 2 , respectively. From the perspective of comprehensively improving the economic benefits of flue-cured tobacco, the optimal fertilization rate is 12.5 kg/666.67m 2 of urea, 18 kg/666.67m 2 of superphosphate, and 33.2 kg/666.67m 2 of potassium sulfate.","PeriodicalId":16596,"journal":{"name":"Journal of Organic Chemistry Research","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84056545","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 experimental results showed that the single treatment of rutile TiO 2 -NPs had little influence on rice chlorophyll content with the concentration of rutile TiO 2 -NPs. Single Cd treatment resulted in an increase in chlorophyll content and the toxicity of high concentration and small size Cd and rutile TiO 2 -NPs had great influence on chlorophyll content in rice. Under rutile TiO 2 -NPs single treatment, single Cd treatment and both, rice transpiration rate and stomatal conductivity gradually increased, but net photosynthetic rate and intercellular CO 2 concentration significantly decreased. The transpiration rate, intercellular CO 2 concentration and stomatal conductivity were not significantly different from the control, but the net photosynthetic rate changed differently under the combined stress of rutile TiO 2 -NPs and Cd. The content of Cd and Ti in roots of rice were much greater than those in the leaves. The rutile TiO 2 -NPs could reduce the mobility of Cd, but increase the mobility of Ti. These experimental results can provide some help and reference for exploring the single and joint effect of TiO 2 -NPs and Cd on rice.","PeriodicalId":16596,"journal":{"name":"Journal of Organic Chemistry Research","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84286093","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}

Driven by various non-covalent interactions, supramolecular systems based on host-guest interactions exhibit fascinating properties due to the introduction of macrocyclic agents.

The characteristics of the total and available content of Fe, Mn, Cu, and Zn in the soil and their profile distribution were analyzed. The results show that the content of iron, copper and zinc in the soil has a very significant negative correlation with the soil sand content, and a very significant positive correlation with the clay content. Shale > quartz sandstone; manganese content is significantly positively correlated with silt content, on average, sand shale > old weathered crust > quartz sandstone on soils developed from different parent materials. In soils developed from different parent materials, there is little difference in the average content of available iron; the average content of available Mn is sand shale > old weathered crust > quartz sandstone; the average effective Cu content of sand shale is greater than that of old weathered crust and quartz sandstone; the average Zn content in sand shale and quartz sandstone is greater than that in old weathering crust.
