The Research On Cultivation Techniques Of Purple Yam In Cui Ping District,Yibin City

In recent years,As the reform agricultural supply side,people have more requirements on the variety and quality of vegetables,demand for organic vegetables,specialty vegetables,and experiential growing is increasing.Purple yam is a herbaceous creeping plant of Dioscoreaceae,It is a new variety developed through cultivation in recent years.Purple yam have Anthocyanins,polyphenols etc,have high development of the research of quality resources,the planting area keeps increasing,the planting technology is constantly improved,continuously promote deep processing field.In recent years,there are also planting in Yibin area,but there are problems such as low yield,insufficient refinement of planting technology,and weak pertinence of pest control programs.In order to promote the healthy development of purple yam industry in Yibin area.In this experiment,Baihua town,Cuiping district(formerly Baihua town,Yibin county)with planting experience and suitable climatic conditions was selected for planting experiment.By setting up four factors of transplanting treatment,seedbed treatment,soil treatment,and planting trough treatment,16 treatments and 48 plots of comparative experiments,the yield and quality were determined,and the occurrence of diseases and insect pests were recorded.Through the experiment,it was found that the optimal treatment was seedling transplanting,transplanting in the planting groove in the right direction,planting in the sandy loam,filling cow manure in the planting groove(that is,treatment 12).Production on 2101 g/strain,3151.5 kg / 667 ㎡,more than one year(1700 kg / 667 ㎡)increased by 85.38%,Compared to the regular planting of Gaochu 46.58 %,The anthocyanin content is 4.89 mg/100 g,the polysaccharide content is 0.75 mg/100 g,and the polyphenol content is 43.55 mg/100 g,are the highest test,corresponding to the pest control scheme can effectively improve the control effect.Through summarizing and forming a set of effective planting techniques in cuiping district of yibin city,we have done a good job in seedling transplanting,seedbed treatment and fertilizer and water management,paid attention to disease and insect pest control,which can effectively improve the yield and quality,and can be widely used in field production.
