“…The dry basis moisture of the soil decreases from eastern to western China. The components and particle size of all the soil types are totally different in China, even in one province due to the regional difference [28][29][30] The Yangtze river, Yellow river, Heilongjiang river, Songhua river, Huai river, Liaohe river, Haihe river and Pearl river are the major natural rivers in China. The Beijing-Hangzhou grand canal is the famous artificial river in China.…”

The unmanned underwater tracked bulldozer (UUTB) is an indispensable equipment for dredging and cleaning obstacles on the river bed in the flood season. The investigation on the interaction properties between the UUTB tracks and sediments provides foundation for the evaluation of operation performance when it works on the inland river bed. Based on the current worldwide research, the sediments mixed by sand, bentonite and water with sand content 0%, 10% and 20% were configured in this study to replace the real sediments on the inland river bed in China. The current pressure-sinkage model and shear stress-shear displacement model were discussed. Three different tracks were tested for the pressure-sinkage and the shear stress-shear displacement on the platform. The relationship between pressure and sinkage under sand content 0%, 10% and 20% are revealed based on the experimental results. The modulus of cohesive deformation and friction deformation of the sediments under said sand content are presented. The curves of shear stress and shear displacement are also obtained, which demonstrates the properties between the tracks and configured sediments under sand content 0%, 10% and 20%. The relationship between the tractive force and slip ratio with three different tracks under said sand content is also presented based on the quantitative analysis, which provides reference for the dynamics control and performance evaluation of UUTB on the inland river bed.

Plant can establish a mutualistic symbiosis with arbuscular mycorrhizal (AM) fungi to improve plant growth and resistance to environmental stresses. The aim of this study was to evaluate the effect of AM on nutrient accumulation of wheat (Triticum aestivum L.) plants under combined elevated CO2 and soil salinity. The effects of CO2 elevation (700 ppm) and salt treatments (0, 1, and 2 g NaCl kg−1 dry soil) on the nutrient accumulation of wheat plants inoculated with AM fungus (Rhizophagus irregularis) were investigated. The AM root colonization was decreased by salt treatment and increased by elevated CO2. AM symbiosis significantly increased shoot dry weight and the accumulation of total C, N, K, Ca, Mg, and Na under elevated CO2 and salt stress. Plant dry biomass was positively correlated with total N, K, Ca, and Mg accumulation, whilst it was negatively correlated with Na accumulation. The concentrations of soluble sugar and glucose in shoots and roots of the AM plants were higher than of the non‐AM plants. It is suggested that AM enhances carbohydrate assimilation and nutrient accumulation in wheat exposed to elevated CO2 and soil salinity.

Optimizing the antenna size by reducing the chlorophyll (Chl) content is an effective strategy to improve solar energy conversion efficiencies in dense crop monocultures. To elucidate the physiological and molecular mechanisms that regulate Chl biosynthesis and understand the effects of lower Chl content on the photosynthetic process, a light-intensity-dependent yellow-green wheat mutant (Jimai5265yg) was characterized to determine its morphological, histological, physiological, and transcriptional differences with wild type. In addition to lower Chl content with a higher Chl a/b ratio, Jimai5265yg has spherical chloroplasts with few plastoglobule. It is counterintuitive that the photochemical quantum yield of both photosystem I and photosystem II and the following CO assimilation rate significantly increased, but the value of nonphotochemical quenching decreased, indicating a reduction of the photoprotective capacity of this yellow-green mutant. Analysis of intermediate pools and the expression of genes in the Chl synthesis pathway indicated that Mg-protoporphyrin IX (Mg-Proto IX) synthesis was partially blocked due to the imbalanced expression of Mg-chelatase subunits. Interestingly, the expression of photosynthesis-associated nuclear genes (PhANGs) was upregulated, resembling gun mutants which have defects in the Mg-Proto IX-mediated plastid-to-nucleus signaling pathway. A genetic analysis indicated that the yellow-green phenotype was controlled by two nuclear recessive genes located on chromosomes 4AL and 4BL. Jimai5265yg is a novel chlorina mutant which could be used for understanding photosynthesis improvement mechanisms.
