Study On Ecological Farm Planning Based On The Principle Of Agricultural Ecology

Based on a specific farm planning practice as an example, research onecological farm planning method.1.Through the analysis of the current structure of the ecological system of agriculture farm identification and function, studies the present situation of the system structure of species, primary productivity and potential, auxiliary energyinput and conversion characteristic and system of material circulationcharacteristics.2.Based on the concept of ecological management, using the geographic information system (GIS) technology, the main ecological factors in the soil on the farm environment,Including soil fertility factor:organic matter, nitrogen, phosphorus, potassium;cadmium, lead and other heavy metals harmful factor, through the grid soilsampling and analysis, on the characteristics of spatial distribution of geo statistical analysis.The results showed that the content of the farm, organic matter, available potassium of belongs to the medium level, which belongs to the low level ofnitrogen; Cadmium, lead, zinc, copper and belongs to the Second level.3.Through the analysis of spatial interpolation and digital technology of GIS,establish the precision distribution map of soil nitrogen, phosphorus, potassiumand other fertility factor and the cadmium, lead and other heavy farm space, fornutrient management planning and heavy metal farms refinement of the local control treatment planning and provide an important basis.Visually and accurately determine the spatial heterogeneity of farm soil. In order to arrange the crop rational layout in the planning of the farm.4.The principle and analysis of agricultural ecology based on the farm, the design of eco agricultural model, and through the comparison of the optimization, reform of the existing agricultural ecological system, ecological agriculture system design, established a relatively perfect ecological farm.Whether from the structure or function, system current is better than farecosystem after planning.Its main characteristics are as follows:(1)Ecosystem structure added, Chicken breeding system,Vegetable subsystem, biogas pool system, edible fungus systemand others.(2)The utilization rate of the light energy prediction planning farm, the ratio of output to input ratio, energy input structure, circulation index can be greatly improve.(3)Matter and energy can be reused and recycled many times use in the system,Within the system of nutrient ratio will be raised, soil nutrients will also continue to increase, the nutrient pool strengthen internal circulation.As far as possible to reduce the input, more output, to achieve economic,ecological, social benefits of the comprehensive effect.5.Method of integrated innovation ecological farm planning.Through the research and application of agricultural ecology principle, for thestructure and function of reasonable adjustment of farm ecological system, make full use of farm resources, realize the farm ecosystem sustainable and stable development, provides certain theoretical approaches.
