Influentce of Production Environment and Condition on Rice Yield in China——An Empirical Study based on 1 540 Rice Farming Households in Hunan, Zhejiang and Heilongjiang
The rice production area in China is widely distributed with great differences in production environment and condition.Changes of different degrees have taken place in farmer household's annual rice production scale,production input,production environment and conditions.At the same time,the national rice policies were also changed.In 2015,investigation was carried out based on 1 540 farmer households in Hunan,Zhejiang and Heilongjiang Provincies,compared the quota varied differences of each production factor in different years,and studied the effect of rice production environment and condition factors on rice yield,so as to better understand the nature & degree intrinsic effect on rice production.By comparison,it was found that the main factors of rice production presented variation features of different degrees.There were significant correlation between rice yield and whether planting super rice variety,rice production environment and rice production conditions.Among all factors affecting rice production,at P＜0.01 level,3 factors had significant correlation with rice yield:whether rice grower satisfied with rice variety,were they willing to plant super rice variety,were they satisfied with rice policies and measures.At P＜0.05 level,besides above 3 factors,there were significant relations between rice yield and 5 factors:rice plantation scale,soil fertility level,basic irrigation and water conservancy conditions,water guarantee of peddy fields and degree of mechanization.Based on analysis and study,this paper put forward conclusions and suggestions for improving rice variety,vigorously developing super rice,improving production condition,and keeping the continuity of policies and measures.
