Research On Forage Distribution And Development Model Of Herbivorous Animal Husbandry In Anhui Province

Herbivorous animal husbandry is an important industry related to the national economy and people’s livelihood.Meat,eggs and milk are important varieties of people’s "vegetable basket".At present,the problem of meat consumption structure is prominent,and herbivorous animal husbandry is in urgent need of development.At present,the development of herbivorous animal husbandry in Anhui Province is slow and the development mode is single.In the Opinions of General Office of the State Council on the Development of Herbivorous Animal Husbandry,it is clearly proposed to promote the high-quality development of animal husbandry and improve the forage feed supply system.The quantity and quality of forage in Anhui Province are unknown,and the total amount and distribution of forage in Anhui Province are not completely clear,which restricts the development of herbivorous animal husbandry.By studying the quantity and distribution pattern of forage in Anhui Province and combining with the development status of herbivorous animal husbandry,this paper analyzed the influence of forage distribution on herbivorous animal husbandry,and promoted the development of herbivorous animal husbandry in Anhui Province by optimizing the distribution of forage.According to the field investigation,the problems existing in the development of herbivorous animal husbandry in Anhui Province were analyzed comprehensively,and the development countermeasures and modes were put forward.In this paper,the influence of forage distribution on the development of herbivorous animal husbandry was studied as follows:Thirdly,In this study,3S technology and geostatistics related methods were used to extract a total of 3,563 forage plots(214,254.66 hectares)through remote sensing image data inversion and field investigation.Among them,3171 plots of forage grass were planted,covering an area of 48079.2 hectares.There are 392 contiguous grasslands over1000 mu,covering an area of 166175.46 hectares.A total of 2395 data of herbivorous animal husbandry points were extracted.Through field investigation,it was found that the main feeding modes of herbivorous livestock in Anhui Province were natural grassland grazing,artificial grassland grazing,cultivated forage intensive house feeding and purchased forage intensive house feeding.Secondly,The distribution pattern of forage was studied by the nearest neighbor analysis,regional analysis,function analysis and density analysis.The study showed that the expected average distance of forage distribution in Anhui Province was 2898.87 meters,the observed average distance was 1772.47 meters,and the average nearest neighbor of forage distribution was 0.478,lower than 1.Therefore,the distribution type of forage distribution in Anhui Province was cluster distribution.The expected average distance of herbivorous animal husbandry distribution is 2202.68 m,the observed average distance is4727.64 m,and the nearest neighbor is 0.466,lower than 1.The distribution type of herbivorous animal husbandry in Anhui Province is also cluster distribution.By comparing the total output value of animal husbandry in Anhui Province with the natural forage and cultivated forage of more than 1000 mu and the distribution pattern,it was found that the distribution of forage in each city of Anhui Province was uniform,and the mean value of the nearest neighbor between forage and herbivory animal husbandry in Anhui Province was only 99.68 meters.Forage has a great influence on the development of herbivorous animal husbandry.The distribution,yield and utilization rate of forage grass directly restrict the development of herbivorous animal husbandry.Thirdly,Through the study,it was found that the distribution of forage in Anhui Province was uneven and unreasonable.In northern Anhui Province,the distribution of forage was dense and there were many herbivorous animal husbandry enterprises,so there was a shortage of forage.The distribution of forage grass in many woodlands in southern Anhui is relatively dispersed,and it is difficult to utilize large areas of natural grassland.The breeding,planting and processing of high quality forage grass in the province are at a low level,and the mechanization degree is very low.Combined with the results of field investigation,it is concluded that there are some problems in the development of herbivory animal husbandry in Anhui Province,such as unscientific spatial distribution,serious problems in the utilization of natural grassland,low mechanization of forage variety,slow development of artificial forage industry and incomplete establishment of scientific development concept.The herbivorous animal husbandry in Anhui Province can achieve faster development by optimizing forage distribution.To solve above problems puts forward optimized forage grass resources distribution,the forage grass to mass production,enhancing professional and technical strength and promote the development of moderate scale cultivation,countermeasures,according to the situation of forage grass distribution pattern and plant-eating animal husbandry development in anhui province put forward four kinds of development model,key resource conservation,breeding production,combination,respectively according to the construction of industrial park for the gripper and four patterns beautiful ranch,It is expected to provide theoretical guidance for the development of herbivorous animal husbandry in Anhui Province,so as to realize the increase of farmers’ income and agricultural efficiency and optimize the construction of rural ecological civilization,which is of great significance for promoting the rural revitalization strategy.
