The Breeding And Cultivating Techniques Of New Radish Variety "Su Zhou Qing"

China is one of the origins of radish,has the most abundant radish germplasm resources in the world,and owns a rich variety of types formed by the long-term evolution and selection.Green radish contains a variety of nutrients,can be cooked,can be processed,can be used for medicine,but also can be used as fresh fruit,favored by the vast number of consumers.All parts of the country have remained more local varieties,and most excellent local breeds is still local cultivars,such as Shandong WeifangQing,Tianjin WeiQing,Anhui Maosan radish,Baozhuang radish,Gaotan radish are all typical representative.In order to select suitable green radish varieties for planting in northern Anhui proivnce areas,this study through mining the local variety resources,combined with market from the extensive collection of domestic varieties and planting test and strict test,screening for bolting tolerance,resistant to diseases,high yield,root shape,peel green meat,succulent crisp green radish as breeding material using conventional breeding methods,plant selection,lines between pollination and lines in hybrid pollination,varieties comparison test,regional test and production test,quality identification bred new varieties of green radish,Suzhou green radish fruit,and the main fanning the identification of new varieties in Anhui Province.The variety has the following prominent advantages:1,good merchandise traits:Fleshy Root cylindrical,green green meat,dense meat,sweet crisp,not hollowing,resistant storage;2,good quality:taste good,rich in nutrition,high content of Vc;3,high yield:fleshy root of uniform size,high commodity rate,test more than 4000kg per mu;4,disease resistance:no disease occurred in many trials.Effects of nitrogen,phosphorus and potassium on the growth,yield and quality of Suzhou green radish.The experiment can see,and quality indexes of nitrogen,phosphorus,potassium and carrot nitrate content,soluble sugar content,Vc content and soluble protein content has close relationship,different nitrogen,phosphorus and potassium nutrition is through a series of physiological and metabolic activities to influence the quality parameters of vegetables.The quantitative relationship between them adjustment mechanism,should be the future of physiology of vegetable quality research key content:at the same time,nitrogen,phosphorus and potassium nutrition on the quality parameters of vegetables,such as amino acids,organic acids,vitamins and other compounds of research need to be further strengthened,broaden vegetable quality factors of content,in order to have a more comprehensive,objective and scientific study explain effect of nitrogen,phosphorus and potassium nutrition on quality;nitrogen,phosphorus and potassium nutrition on Radish Growth Index RGR,NAR and lar is complex,pending further study.Light illumination,temperature,moisture,CO2,O2 and inorganic nutrients such as photosynthesis,respiration and organ growth environmental factors can affect the RGR,LAR and NAR,so under different growth conditions,the growth index of the value of the can is relatively poor;at the same time,these parameters available to the analysis of plant growth responses to environmental conditions.Also,people focus more and effect of nitrogen,phosphorus and potassium on the quality of vegetables,the next step,of other mineral elements such as calcium,magnesium,boron,zinc,effects on quality of vegetables on should also become the focus of research,further understand the factors that influence the quality of vegetables,in order to further improve the vegetable quality to meet the needs of the masses of the people.
