Discussion On Comprehensive Utilization Status And Development Strategy Of Crop Straws In Yan Jiagang Farm

China is a large agricultural country,rich in straw resources.In recent years,there has been a continuous "fog ting" weather in most areas of China,which has brought a lot of harm to people's production and life.One of the main reasons for this phenomenon is straw burning.Straw burning not only pollutes the environment,but also endangers human health.Therefore,reasonable and effective straw comprehensive utilization is particularly important.Crop straw,as an important biological resource and scarce resource,is a natural renewable energy.With the progress of science and technology,the comprehensive utilization of straw resources has become the focus of modern agricultural development.But yanjiagang farm crop straw is discarded at will,and the phenomenon of on-site burning is relatively serious.The straw resources cannot be effectively integrated and utilized.Therefore,this paper provides a reference for the efficient material conversion and energy recycling of the farm in the agricultural production system,and also conforms to the modern development concept of resource conservation,energy conservation and emission reduction.Based on Yan jiagang farm actual situation,the methods of literature review,case study analysis on the current situation of comprehensive utilization of crop straw combed through farm straw comprehensive utilization present situation analysis,find the problems existing in the straw utilization,combining objective factors such as natural condition and development of the farm,targeted,practical and feasible countermeasures and Suggestions.At present,there are five ways of straw comprehensive utilization in yanjiagang farm,including straw mechanical return to the field,straw production of organic fertilizer,straw resource forage,intelligent greenhouse substrate cultivation,and straw cultivation of edible bacteria.In terms of comprehensive utilization of straw,there are some problems,such as imperfect policies and measures,insufficient understanding of farmers,lack of technology,lagging industrialization level and lack of supporting equipment.Yan jiagang farm near Harbin metropolis,it is suggested that in the process of comprehensive utilization of straw give full play to the characteristics of geographical location,on the premise of perfecting the use way,should be produced with straw cultivation matrix as the use of a key,and other forms,melon,fruit,flowers,food,edible fungi,such as organic farming industry,promote the sightseeing agriculture,picking the development of agriculture,ecological agriculture,to make more effective and reasonable use of farm of straw,to improve the economic benefits of straw utilization,ecological and social benefits.
