文摘[Objectives]Amygdalus tangutica is a new and excellent tree species for afforestation in arid areas of central China for soil and water conservation.It has the characteristics of drought resistance,cold resistance and tolerance to poor soil,and has strong ecological,landscape and economic value.To provide a theoretical basis for the propagation and application of A.tangutica in Minqin and similar arid sandy areas of Northwest China,this paper explored its introduction and cultivation technology through field experiments,considering the natural geographical conditions of the study area.[Methods]High-quality seeds were introduced from forest farms of Chankou Town,Anding District,Dingxi City,and Dian ga Town,Diebu County,Gannan Prefecture,and the introduction and cultivation experiments of A.tangutica were carried out in the greenhouse of Wuwei Oasis Station.[Results](1)Soaking treatment at different temperatures combined with gibberellin treatment and stratification germination could effectively break the dormancy of A.tangutica seeds,thereby accelerating germination and shortening the germination cycle.The germination peak appeared 15-20 d after sowing,and the final germination rate could reach about 50%.(2)In the introduction and cultivation of A.tangutica in arid areas,large fruit seeds with higher thousand-grain weight should be given priority.The emergence rate of large fruit seeds was significantly higher than that of small fruit seeds,with the highest reaching 57%,while the highest of small fruit seeds was only 20%.Soaking treatment at different temperatures had no significant difference in the germination performance and germination potential of A.tangutica seeds,but the germination index of large fruit seeds was higher than that of small fruit seeds.(3)Under the current conditions,seedling propagation is a reliable way to propagate A.tangutica in arid areas.The cutting propagation technology,particularly hardwood cutting which exhibits an extremely low survival rate,is not yet mature and is currently unsuitable for large-scale production.Consequently,future efforts should prioritize more in-depth research on softwood cutting techniques.[Conclusions]This study provides a theoretical foundation for the propagation and broader application of A.tangutica in Minqin and similar arid sandy areas of Northwest China.
文摘In the context of the new era,deepening education reform and improving the quality of talent cultivation are important measures for universities to align with industry trends and the development needs of students.With the continuous growth of the economy,the construction industry is undergoing rapid development and transformation,and there is an increasing demand for high-quality and high-level applied talents,which poses certain challenges to the architecture majors in universities.Therefore,universities should actively follow the industry development trends and the characteristics of talents,clarify the talent cultivation objectives,optimize the professional teaching system,and promote the high-quality development of education.The cultivation of applied talents in the architecture major of universities is not only an internal requirement for the development of the construction industry but also an important part of the country’s innovation-driven development strategy.It is of great significance for promoting scientific and technological progress,enhancing cultural confidence,and promoting the comprehensive development of the economy and society.
文摘Significant variations in global temperatures and weather patterns over time are known as climate change.Although it occurs naturally,human activities—particularly the burning of fossil fuels,deforestation,and industrial processes—are accelerating these changes,which have various detrimental effects on the environment.This review aims to highlight the edapho-climatic requirements of this cactus and the advantages and challenges of its cultivation to mitigate climate change.The prickly pear cactus is a plant with numerous financial and environmental advantages.It needs well-draining,sandy or gravelly soil to avoid root rot and do best in full sun.With a strong tolerance for dryness,they thrive in arid or semi-arid regions with scorching summers and prefer sparing watering.Despite being suited to tropical climates,some species can tolerate freezing temperatures and sporadic frost.Once established,these hardy plants require little care and thrive in nutrient-poor soils,which makes them perfect for xeriscaping or challenging growing environments.Because of its high water use efficiency ratio and low water requirements,prickly pear can be grown in marginally dry and semi-arid areas.The cactus does contribute to the ecological and socioeconomic fight against climate change.For instance,it supports sustainable agriculture,biodiversity preservation,soil restoration,carbon sequestration,and effective water usage.Demarcating dry and semi-arid zones and fostering employment in these areas is beneficial from a socioeconomic standpoint.The prickly pear’s traditional cultural heritage supports its current economic function as a crop that can withstand drought.While ecological threats necessitate balanced management,this adaptability promotes sustainable growth.Innovations in bioenergy and value-added goods build on its historical applications,increasing its socioeconomic advantages and,eventually,its worldwide significance.

文摘The Liaohe River Valley was one of the key centers of the origination and development of agriculture in northern China during the Holocene.To understand the long-term interaction among the evolutions of climate,agriculture,and human activities,it is essential to quantitatively reconstruct the spatiotemporal changes in regional prehistoric human land use.In this study,known archaeological sites and a prehistoric land use model(PLUM)were combined to reconstruct changes in land use in the Liaohe River Valley during 8-2 ka BP from a quantitative perspective.The land use area experienced two stages of increase(during 8-5 ka BP and after 4 ka BP)and one stage of decrease(during 5-4 ka BP);these periods were characterized by spatial expansions and contractions.The land use intensity level differed significantly in the western and eastern parts of the valley before 4 ka BP,but the situation changed as the distribution center of the human activity shifted to the southern part of the valley around 5-4 ka BP.Overall,the spatial and temporal changes in the land use areas in both the western and eastern parts of the valley responded well to variations in precipitation during 8-2 ka BP,which potentially provides useful insights into understanding the responses of human activity to future climate change.
文摘Climate variability significantly impacts agricultural water resources,particularly in regions like Vietnam's Plain of Reeds that heavily utilize rain-fed conditions.This study employs the FAO-AquaCrop model to estimate current and future irrigation water needs for rice cultivation in this critical subregion,aiming to identify optimal sowing schedules(OSS)that enhance rainwater utilization and reduce irrigation dependency.The model was driven by current climate data and future projections(2041-2070 and 2071-2099)derived from downscaled Global Circulation Models under RCP4.5 and RCP8.5 scenarios.The AquaCrop model demonstrated robust performance during validation and calibration,with d-values(0.82-0.93)and R²values(0.85-0.92)indicating strong predictive accuracy for rice yield.Simulation results for efficient irrigation water potential(IWP)under RCP4.5 revealed that strategic shifts in sowing dates can substantially alter water requirements;for instance,advancing the winter-spring sowing to December 5th decreased IWP by 15.6%in the 2041-2070 period,while delaying summer-autumn crop sowing to April 20th increased IWP by 48.6%due to greater reliance on irrigation as rainfall patterns shift.Similar dynamic responses were observed for the 2071-2099 period and for autumn-winter crops.These findings underscore that AquaCrop modeling can effectively predict future irrigation needs and that adjusting cultivation calendars presents a viable,low-cost adaptation strategy.This approach allows farmers in the Plain of Reeds to optimize rainwater use,thereby reducing dependency on supplementary irrigation and mitigating the adverse impacts of climate variability,contributing to more sustainable agricultural water management.
