The Study On The Influencing Factors Of Rapeseed Production In Hubei Province Based On Grey Correlation Analysis

Rape is one of the 4 major oil crops,because of its high oil content,high nutritional value and characteristics of planting has a long history of cultivation in our country,and the products of rapeseed oil because of its abundant nutrition has become the necessities of daily edible oil,the rapeseed is the most important oil crops in China;Hubei province is the province rapeseed planting area in China,the largest rapeseed yield the largest,with the development of rape industry in Hubei Province,the development of rapeseed production has gradually formed a complete series of rape planting,processing and sales of rapeseed rapeseed oil industry chain,study on the factors of rapeseed production in Hubei is affected not only directly related to the rape yield level is closely related with the healthy development of Hubei rape industry and national grain safety.Through using the method of grey correlation analysis,were selected for rapeseed in Hubei Province total yield and yield of rape,rape planting area,planting cost and rapeseed oil prices five aspects of the impact factors of the grey relational analysis,expect to strengthen improvement of rapeseed production in Hubei Province as well as the development of oil industry to provide a reference.The first chapter is the preface part.The second chapter is the analysis of the present situation of rapeseed production in Hubei Province,respectively,to study the its growing regional distribution characteristics,1978-2013 total yield,yield,planting area of the data change,production advantages and rapeseed production existing problem was analyzed,such as the relatively low efficiency of rapeseed production,rape quality poor,rape production mechanization degree low.The fourth chapter through earlier rapeseed production in grey system theory elaboration and the introduction of calculation method of grey correlation degree,respectively,to construct the grey correlation model of 2008-2012 total yields of rapeseed production in Hubei Province,yield,the planting area,planting cost,the price of rapeseed,according to the calculation method for grey correlation degree that influence on rape total production,yield,planting area,the leading factor of the cost and the price of rapeseed planting.The fifth chapter is the conclusion and suggestion.According to on the basis of previous research on enhancing the Hubei Province rape yield,enhance rapeseed farmers in the acquisition price of three point of view put forward countermeasures and suggestions of initiative and control the rapeseed plant.By using the grey relation theory of rapeseed production in Hubei Province in the total yield,yield,the planting area,planting cost,rapeseed price influencing factors were studied,results show,to promote the use of rape planting area,rape varieties and Fertilizer on yield of rapeseed in Hubei Province the influence degree of the larger;the end of cultivated land resources,rapeseed yield and Mu rape planting cost larger;input factors of production data,operating lease fees and acres of artificial cost to the extent of the impact of rape planting in Hubei Province cost larger;rape production and per capita consumption of vegetable oil effect on rapeseed prices degree larger factors having effect on the rape planting in Hubei Province area.Therefore,in order to improve the yield of rape must increase investment in science and technology,R&D rape high yield new varieties and to ensure that rape planting area;at the same time,enhance the cultivation of rapeseed farmers enthusiasm,reduce rape planting cost,stability of rapeseed purchasing price,the most fundamental is to the stable yield of rape.Therefore,increasing investment in science and technology,strengthen the research and development of high yield of rape seed pest resistance,improve the level of mechanization of rape production,is the key to the stability of rapeseed production in Hubei province.
