Résumé partiel
The Party Central Committee and the State Council issued the strate gic plan for rural revitalization strategy(2018-2022),which proposed to e xplore advantageous ecological industries,promote the restoration of ecol ogical environment and the development of ecological industries,focus o n planning the industrial layout in karst rocky desertification areas,reason ably design the development model of ecological industries,and strive to build environment-friendly agriculture(background of the topic).At pres ent,the area of China’s ecological industry is about 10 million hm 2,accou nting for 12%of China’s cultivated land,with an annual output value of 100 billion US dollars.At the same time,the development of ecological in dustry in rocky desertification control areas is guided by economic growt h and ecological restoration.The research on water and fertilizer coupling mechanism and product quality improvement technology of ecological in dustry is of great significance to effectively solve the"issues concerning agriculture,countryside and farmers"and promote rural revitalization stra tegy in rocky desertification areas.This study uses the theories of geograp hy,ecology,pedology,soil fertilizer,botany,hydrology,regional econom ics and natural resource value to solve the scientific issue and scientific a nd technological needs of Zanthoxyhum planispinum var.dingtanensis w ater and fertilizer coupling,the mechanism of Zanthoxyhum planispinum var.dingtanensis quality on water fertilizer ratio sceme,formula fertilizat ion,water use strategy,water and fertilizer use efficiency.From 2018 to 2021,Guanling Zhenfeng Huajiang in the mountainous area of Guizhou Pl ateau was taken as the research area.Through continuous investigation,c ontrol experiment,ecological environment and pepper product data collec tion in the study area,the water and fertilizer coupling mechanism,comm on key technology research,application demonstration and industrializati on promotion of Zanthoxyhum planispinum var.dingtanensis are analyze d by using Bayesian equation,wavelet coherence analysis,input-output m odel.This study focuses on clarifying the water and fertilizer coupling me chanism of Zanthoxyhum planispinum var.dingtanensis,explaining the ut ilization characteristics and efficiency of water and fertilizer in Zanthoxyh um planispinum var.dingtanensis,and putting forward the key technologi es for improving the quality of Zanthoxyhum planispinum var.dingtanens is.The results provide scientific and technological reference for the water and fertilizer coupling mechanism of Zanthoxyhum planispinum var.din gtanensis,the improvement of product quality and the revitalization of ru ral ecological industry.
