Study on Effects of Organic and Conventional Planting Modes on Quality and Economic Benefits of Rice in Yunnan
摘要
Abstract
The aims are to develop green organic agriculture,promote organic planting models,vigorously advance sustainable development strategies,explore effective organic planting models,and study the cultivation of organic and conventional rice under the rotation mode of'rice+broad bean+rice'.The experiment adopted adjacent planting in the field,set up duplicate and control groups,and the detection of various indicators was determined according to the corresponding national standards.Based on the experimental results,the impact of different planting modes on the quality and economic benefits of rice in Yunnan was analyzed.The results showed that the cadmium and arsenic levels in the organic planting mode were lower than those of the conventional rice,and the contents of lead,chromium,and copper were all higher than those of the conventional rice.The organic+mode had higher contents of other heavy metals except for cadmium,which was lower than that of the conventional rice.Through analysis of variance,P>0.05,the differences in various safety quality indicators between different treatments were not significant;the nutritional quality of rice was higher than that of conventional planting,except for dietary fiber,which was lower than that of conventional planting.All nutritional quality indicators of the organic+mode were higher than those of conventional planting.The overall nutritional quality of the organic planting mode was higher than that of conventional planting.Organic planting could improve the nutritional quality of rice to a certain extent,but after analysis of variance,P>0.05,the difference was not significant;Organic planting had high initial production input costs and lower yields than conventional planting.However,the market price advantage of organic rice was obvious,and the final profit was 2.5 times that of conventional planting,with good economic benefits.By comparing the two different modes of conventional planting and organic planting,this study provides a theoretical basis and practical reference for further optimizing the rice industry structure in Yunnan and improving the planting mode in some areas.关键词
