In high slope site, the yield ended up being significantly correlated with soil water content (SWC), earth organic matter (SOM), available potassium (AK), with AK showing the most important effect. The yield of pear in center and reduced pitch websites had been significantly correlated with SWC, SOM, and total nitrogen (TN), with SWC getting the most significant effect on yield. The items of SWC, SOM, offered phosphorus (AP) and TN in high slope website had been more than in center and low slope sites, while AK ended up being the highest in center slope web site. 2) Among different earth depths, soil nutrient contents had been the highest within 0-20 cm soil layer, but the lowest within 20-40 cm soil layer. The SWC ended up being dramatically reduced within 0-20 cm as compared to various other earth layers and had been the highest within 20-40 cm soil layer. 3) Among different growth durations, the articles of SOM, AP, and TN had been the best in flowering duration, the SWC had been the best in fruiting period, and AK content had been the highest in maturing period. It absolutely was recommended that in the foreseeable future management of pear liquid and fertilizer in the area, more K fertilizer should really be used when you look at the high slope internet sites when you look at the flowering period, while N and P compound fertilizer must certanly be applied within the fruiting period, to enhance irrigation in middle and reduced slope sites to decrease the restriction of liquid with 300 m3·hm-2. Our outcomes could supply theoretical assistance and data refe-rence for growing accuracy irrigation and scientific fertilization of pear grown in loess hilly places.We reviewed the growth dynamic and bolting price of Angelica sinensis, soil high quality and enzyme activities biogenic nanoparticles and weed density and control effect in a field research under different mulching patterns, to provide theoretical foundation for the application of plastic movie in genuine producing area of A. sinensis. The sowing habits were performed as gap seeding under ridging with plastic-film mulching (LS), trenching and slant sowing under film-side cultivation (MC) and trenching and slant growing in open field (LD). Our outcomes revealed that, 1) compared with LD, soil natural matter content in top layer underneath the treatments of LS and MC ended up being increased by 4.4per cent and 14.3%, respectively, with this under MC becoming statistically considerable. Earth volume density was significantly diminished by 11.6per cent and 8.5%, while pH ended up being significantly diminished by 4.6% and 1.7%. The activities of soil sucrase, phosphatase and urease were dramatically increased because of the two mulching methods, but compared to catalase had been inhibited to a certain extent. 2) Mulching film improved the speed of coming back green after transplanting, early bolting price, plus the specific medicinal high quality of A. sinensis. MC showed the quickest, the most uniform, plus the greatest greening rate. LS bolting price had been the greatest, together with fresh mass of MC and LS was dramatically increased by 20.4per cent and 58.4%, respectively. 3) Weed density under the treating MC and LS was significantly reduced by 34.0per cent and 25.8%. Compared with LS, MC considerably enhanced the control effect of plant and fresh size by 21.7% and 63.4%, correspondingly. In summary, movie cultivation techniques could improve the environment for root growth, reduce weed thickness, improve weed control effect, and advertise development process and compound buildup, but could advertise the bolting of A. sinensis at the beginning of stage.A field experiment had been carried out using Hanfu apple grafted on 10 dwarfing interstocks to evaluate plant development, yield, and fruit top-notch different apple-interstock combinations in Hulu-dao, Liaoning Province, so that you can choose the the best option apple-interstock combinations within the research location. The outcomes revealed that tree vitality, yield, and fruit quality were largely afflicted with Papillomavirus infection the interstocks. Among the list of interstocks examined here, plant level, branch figures, leaf fresh weight, branch fresh body weight, root fresh body weight, complete root volume, normal root diameter and total root tip numbers had been the biggest on GM256, while the highest trunk diameter, part size, complete root size and total root area had been observed on CX5, the highest fruit firmness, dissolvable solids and soluble sugar items were seen on M26, in addition to greatest fruit straight diameter, transverse diameter and solitary good fresh fruit check details weight had been observed on GM256. The fuzzy analysis outcomes showed that the comprehensive personality scores diminished if you wish of GM256, CX5, B9, JM7, CG80, Liaozhen 2, M26, Qingzhen 3, SH38 and MD001. Our outcomes indicated that interstock GM256 and CX5 was better for the cold climate region.As a clean and green renewable energy source, wind power lures more and more attention globally, and quickly expands its usage scale. There are disputes between wind power development and bird defense. The effects of wind farms on wild birds is a hot subject for ecologists and conservationists. To estimate the consequences of wind generators on avian species diversity and their particular useful and phylogenetic diversity, we carried out line transect studies in January, March, April and May 2019. Thirty-two line transects had been divided into four gradients in line with the distance from the wind turbines, i.e., 100-300 m (6 transects), 300-500 m (13 transects), 500-700 m (8 transects), >700 m (5 transects). The results showed that a total of 76 resident reproduction birds were recorded, belonging to 11 instructions and 31 people.
