| 1 | Soil Fertility,Microbial Biomass,and Microbial Functional Diversity Responses to Four Years Fertilization in an Apple Orchard in North China显示文摘Soil microbial communities play an essential role in maintaining soil fertility and are considered as ecological indicators to evaluate soil health.In the present study,we examined the influence of almost 4 years of fertilization[no fertilizer(CK),nitrogen alone(N),nitrogen,phosphorus and potassium chemical fertilizer(NPK),organicmanure(M),nitrogen plus organic manure(NM),and NPK plus organic manure(NPKM)]on soil fertility and the functional diversity of soil microbial communities in an apple orchard.Compared to CK,fertilization increased soil organic carbon,total nitrogen,and available nutrients,but reduced soil pH in N and NPK treatments.The highest microbial biomass carbon and nitrogen,most probable number of actinomycetes,bacteria,and fungi occurred in the NPKM treatment.The average well color development(AWCD)values followed the order of NPKM>M>NPK and NM>CK and N.The Shannon index in organic manure treatments were significantly higher than in control and in treatments without organic manure.The principal component analysis showed that manure treatment was significantly separated from other treatments.These results indicated that organic manure applied alone or in combination with chemical fertilizers would increase soil fertility and functional diversity of soil microbial communities.Moreover,applying balanced N,P,K fertilizer in combination with organic manure was found to be superior to the use of a single fertilizer in improving soil microbial community quality. | Zhanling Zhu Yan Bai Minglu Lv Ge Tian Xin Zhang Li Li Yuanmao Jiang Shunfeng Ge | 2020 | Horticultural Plant Journal2020,6,4: | 13 |
| 2 | Soil Nutrient Status and Leaf Nutrient Diagnosis in the Main Apple Producing Regions in China显示文摘Soil and leaf nutrient analysis are widely used as effective methods of diagnosing nutrient deficiency in fruit trees,the results of which are used to properly manage fertilizer application.Therefore,a survey was conducted for assessment of the soil nutrient status and leaf nutrient concentration in 2 827 apple orchards in the Bohai Bay and Loess Plateau apple production regions of China.The soil organic matter,alkali hydrolyzable N,available P,and available K were 10.91 g·kg^(-1),73.21 mg·kg^(-1),70.22 mg·kg^(-1),and 169.23 mg·kg^(-1)in the Bohai Bay region,respectively,and 11.72 g·kg^(-1),56.46 mg·kg^(-1),14.91 mg·kg^(-1),and 135.78 mg·kg^(-1)in the Loess Plateau region,respectively.Soil organic matter was at a medium-to-low level in both regions,whereas the soil alkali hydrolyzable N was low.In the Bohai Bay region,soil available P was high,but soil available K was deficient.In contrast,both soil available P and K were insufficient in the Loess Plateau region.The Diagnosis and Recommendation Integrated System(DRIS)diagnostic results indicated that the most deficient elements were Ca and K in low-yielding orchards(<35 t·hm(-2))of the Bohai Bay region followed by Fe,N,and Zn;however in the Loess Plateau region,the most deficient elements were P and K followed by N,Zn,and Cu.The findings imply that the application of Ca,K,Fe,N,and Zn fertilizer should be increased in the Bohai Bay region,whereas P,K,N,Zn,and Cu fertilizer should be enhanced in the Loess Plateau region.Meanwhile,use of organic manure is recommended to improve soil quality in the two apple producing regions. | GE Shunfeng ZHU Zhanling PENG Ling CHEN Qian JIANG Yuanmao | 2018 | Horticultural Plant Journal2018,4,3: | 12 |
| 3 | Fate of PM2.5-bound PAHs in Xiangyang, central China during 2018 Chinese spring festival: Influence of fireworks burning and air-mass transport显示文摘Variations of levels,possible source and air mass transmission were investigated for 16 USEPA priority-controlled PAHs in PM2.5 during 2018 Chinese Spring Festival(CSF)in Xiangyang City,central China which is the North-South pollutant airmass transport channel of China.Totally 37 samples were collected.Mass concentrations of 16 PAHs for the Pre–CSF day(Pre–CSFD),during the CSF day(CSFD)and after the CSF day(Af–CSFD)are 33.78±17.68 ng/m3,22.98±6.49 ng/m3,and 8.99±4.44 ng/m3,respectively.High resolution samples showed that 16 PAHs are higher in the morning(06:00–11:00)or afternoon(11:30–16:30),than those in the evening(17:00–22:00)and at night(22:30–05:30),whereas the result is reversed during the CSFD.Fireworks burning can obviously increase the mass concentration of PAHs.Air mass trajectory indicated that Xiangyang is a sink area of pollutants for northwest and southeast,and the sources of the northeast and southwest.The air mass only can be transmitted out through northeast and southwest.It is effective for improvement of air quality in Wuhan and Hunan to control fireworks emission in Henan and local areas.Fireworks burning was an important source for PAHs during CSFD,biomass,coal combustion,and traffic emission were the main sources of PAHs for Pre–CSFD and Af–CSFD periods.The health risk on the CSFD was higher than the acceptable levels,especially during the intensive fireworks burning,the risk value far exceed 1.0×10^-4,controlling burning fireworks is required. | Tianpeng Hu Yao Mao Weijie Liu Cheng Cheng Mingming Shi Zhanle Chen Qian Tian Jiaquan Zhang Shihua Qi Xinli Xing | 2020 | Journal of Environmental Sciences2020,32,11: | 6 |
| 4 | Predicting the solar maximum with the rising rate显示文摘The growth rate of solar activity in the early phase of a solar cycle has been known to be well correlated with the subsequent amplitude (solar maximum).It provides very useful information for a new solar cycle as its variation reflects the temporal evolution of the dynamic process of solar magnetic activities from the initial phase to the peak phase of the cycle.The correlation coefficient between the solar maximum (R max) and the rising rate (β a) at Δm months after the solarminimum (Rmin) is studied and shown to increase as the cycle progresses with an inflection point (r=0.83) at about Δm=20 months.The prediction error of R max based on β a is found within estimation at the 90% level of confidence and the relative prediction error will be less than 20% when Δm 20.From the above relationship,the current cycle (24) is preliminarily predicted to peak around October,2013 with a size of R max=84±33 at the 90% level of confidence. | DU ZhanLe WANG HuaNing | 2012 | Science China(Physics,Mechanics & Astronomy)2012,55,2: | 3 |
| 5 | Influence of boron contents on properties of AlMgB films prepared by RF magnetron sputtering显示文摘Ternary AlMgB thin films were synthesized on silicon (100) substrate at 573 K by radio frequency (RF) magnetron sputtering method using one Al/Mg co-target and one boron target. The thickness of the as-deposited thin film was controlled to 500 nm by adjusting deposition time. The influences of sputtering powers on the elemental contents and structural and mechanical properties were investigated by electron probe microanalysis (EPMA), X-ray diffraction (XRD), high-resolution transmission electron microscopy (HR-TEM), and nanoindentation system. At the same time, the ball-on-disk tribometer was used to measure the friction behavior of the films. Experimental results indicate that the as-deposited boron-rich films are primarily amorphous structure and possess a dramatic high hardness up to 39 GPa with 99.03 at.% boron. Obviously, it has exceeded the hardness value of 32 GPa of pure AlMgB 14 bulk material prepared by sintering method. Furthermore, the friction coefficients of the thin films exhibit an average value as low as 0.3, which is considered as the effect of self-lubricating. | Qu, Wenchao Wu, Aimin Wu, Zhanling Bai, Yizhen Jiang, Xin | 2012 | Rare Metals2012,31,2: | 3 |

| 11 | Remove volatile organic compounds(VOCs) with membrane separation techniques显示文摘Membrane separation, a new technology for removing VOCs including pervaporation, vapor permeation, membrane contactor, and membrane bioreactor was presented. Comparing with traditional techniques, these special techniques are an efficient and energy saving technology. Vapor permeation can be applied to recovery of organic solvents from exhaust streams. Membrane contactor could be used for removing or recovering VOCs from air or wastewater. Pervaporation and vapor permeation are viable methods for removing VOCs from wastewater to yield a VOC concentrate which could either be destroyed by conventional means, or be recycled for reuse. | ZhanL WangHX | 2002 | Journal of Environmental Sciences2002,14,2: | 1 |

| 20 | Is a higher correlation necessary for a more accurate prediction?显示文摘A higher correlation tends to yield a more accurate prediction,so that a correlation as high as possible has been searched for and employed in the prediction of solar activity.Instead of using geomagnetic activity during the descending phase of the solar cycle,the minimum annual aa index (aa min) is used as an indicator for the ensuing maximum amplitude (R m) of the sunspot cycle.A four-cycle periodicity is roughly shown in the correlation between R m and aa min.The widely accepted Ohl's precursor prediction method often fails due to the prediction error relative to its estimated uncertainty.An accurate prediction depends on the positive variation of the correlation rather than a higher correlation.Previous experiences by using this method indicate that a prediction for the next cycle,R m (24)=80 ± 17,is likely to fail,implying that the sunspot maximum of Cycle 24 may be either smaller than 63 or greater than 97. | DU ZhanLe WANG HuaNing | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,1: | 1 |
