Analysis On Current Situation And Benefits Of Ecological Agriculture In Guangxi

At present,there are some problems in Guangxi's agricultural development.For example,the capacity of ecosystems to resist natural disasters has weakened,droughts and floods have been very serious;soils have been compacted and land fertility has declined;crop structures have become monotonous,and light energy utilization has been low;the processing capacity of agricultural and sideline products is weak,and agricultural waste has not been used at multi-level;excessive use of pesticides and fertilizers,making agricultural non-point source pollution aggravate,etc.These problems hinder the development of agriculture,and ecological agriculture is an effective way to solve these problems.In this paper,literature research methods,qualitative and quantitative analysis methods,case study methods are used to study the ecological agriculture in foreign countries,the types of ecological agriculture in Guangxi,and the benefits of agriculture.Combined with examples,the "Paddy Fish Farming" ecological agriculture model and the conventional planting model are carried out.For comparative research,the main research contents and results are as follows:(1)The development of eco-agriculture can not be separated from the innovation of various eco-agricultural models.This paper classifies Guangxi eco-agriculture into six types according to the type of land and the characteristics of eco-agriculture in Guangxi:hilly mountainous,plain,suburban,courtyard,water area type and tourism type,each type is divided into different modes of ecological agriculture.(2)Through the analysis of Guangxi's current agricultural efficiency,it can be concluded that Guangxi has made tremendous progress in economic construction,ecological protection,and social stability through more than 30 years of ecological agricultural construction.By analyzing the economic benefits of the "Guangxi Sanjiang Model",the net income for 2015-2017 was:46380 yuan · hm-2,48352.5 yuan · hm-2,43252.5 yuan · hm-2,and the net income of conventional planting pattems was:637.5 yuan · hm-2,-307.5 yuan · hm-2,and-1282.5 yuan · hm-2.The "Sanjiang Model of Guangxi" has also made the income level of farmers better under the premise of ensuring the income of farmers;Reduce the use of pesticides and fertilizers to reduce agricultural non-point source pollution,improve soils,reduce rice weeds and pests;Stabilize food production,improve rice quality,enrich consumers' traditional table culture heritage and have great social value.(3)Through the study of Guangxi's ecological agriculture,it is found that there are problems in the six aspects of technology,capital,policy,industrial chain,service system,and sales channels in Guangxi's ecological agriculture construction,and relevant countermeasures are proposed for these problems.
