Abstract Flue-cured tobacco ( Nicotiana tabacum L.) is a major cash crop in Yunnan, China, and the yield, chemical components, their proportions decide quality of leaves. To understand effects environmental factors (soil climatic factors) on yield flue-cured determine main regulating factors, we selected three cultivars [K326, Yunyan87 (Yun87), Honghuadajinyuan (Hongda)] grown Honghe Tobacco Zone. Indices related to economic traits, component properties, soil physical at different planting...
Abstract Fertilization can be optimized and managed during the flue-cured tobacco growing period by studying response of soil microbial biomass stoichiometric characteristics to fertilization. In this study, we investigated effect compound fertilizers combined with fertilizer treatments on rhizosphere limitations resources period. The results indicated that C:N:P varied greatly sampling time was usually greater than fertilization treatment, did not vary resource ratio. metabolism...
Abstract The excessive application of nitrogen (N) has caused a series environmental problems. Brown earth (BE) is one the main soil types in China, and specific soil‐forming conditions make it high risk nutrient leaching. Determining fertility BE optimal N rates for crops’ production important to reduce Based on China's second national survey, basic level was defined, effects four management methods [one‐time base fertilizer (BF), topdressing (TF), combined organic (OF) controlled‐release...
Abstract Categorization of soil organic carbon (SOC) into different functional subpools according to their recalcitrance and protective mechanisms helps better understand ecosystems (OC) dynamics, various attempts have been made explore the suitable experimental fractionation method for such purpose. However, most previous studies neglected influences environmental factors on effectiveness varying methods. Density has shown great promise in elucidating SOC immobilization mechanisms. Here, we...
Abstract By studying the response of soil and microbial biomass stoichiometric characteristics to fertilization, it is possible optimize effective fertilization management during flue-cured tobacco growing periods. In this study, we studied effect compound fertilizers combined with fertilizer treatments on rhizosphere limitation resources growth The results indicated that C:N:P varied greatly period, sampling time was usually greater than treatment, C: N:P did not vary resource ratios. With...
Abstract Background: Because soil organic carbon (SOC) variation is a result of its physicochemical protection, fractionating SOC into different functional subpools according to protection mechanism and studying the fractions’ responses environmental change will help guide study dynamics. Therefore, we conducted an analysis density-based fractionation 107 sites from 35 literature sources answer following questions: (1) Will methods yield amounts in three pools: free (FOC), occluded (OOC)...
Abstract An in-situ corrosion rate monitor using a carbon steel tube, rod or wire as the sensing element has been developed. The was tested both in an inert system at room temperature and high-temperature high-pressure loop with LiOH solution. Experimental results from tests showed that calculated thinning based on resistance signal of agreed well measured values. responded to changes when air sulfuric acid added. precision under simulated nuclear coolant conditions found be ±0.04 μm ±1...
