The Summer Radish Productive And Efficient Cultivation Technology In Taibai Mountain Area

The unique cold climate in Taibai mountain areas provides favorable conditions for the development of mountain vegetables.The planting of summer radish as the backbone for the local development of vegetable industry has developed more than 7 million square meters in Taibai county, It has played a positive role to support the development of vegetable industry in Taibai.But there is lacking of resources suitable varieties, cultivation methods and irrational in the production process, so we need use the scientific experiment to obtain a set of productive and efficient cultivation techniques that can be used in production of summer radish.In this study, the summer radish suitable seeding time experiment, bolting resistant radish varieties comparison experiment, the influence of different density cultivation of radish yield experiment, different fertilizer experiment, the following conclusions:1.In Taibai mountain areas radish production process, the sowing time should be strictly controlled to prevent bolting phenomenon.In Taibai mountain area,the soil temperature should stable to above 12 ℃ that after this time, generally the security planting dates after May 10.2.Considering all the varieties of yield, Bolting tolerance, disease resistance,market ability and other factors,’Ling Chui’, ’LB-2011’, ’YR angel’, ’Xue Chun Bao 2’, ’Shi You Qing Guang’, ’Qing Sen’, ’Jingfu’ seven varieties were screened out,this varieties was suitable for planting in taibai mountain area.3.Different density cultivation of radish yield and marketability have a greater impact,In the Taibai mountain areas summer radish cultivation process, the optimal density is: line spacing 40 cm, plant spacing 20 cm.4.In the case of the right amount of fertilizer,In the case of the right amount of fertilizer, with the application of organic fertilizer to improve the radish yield have a certain role;Nitrogen is a key factor restricting radish increased yields.The optimum amount of fertilizer is Per 667m2 N fertilizer(urea) 14 kg, P fertilizer(super phosphate) 16 kg, K fertilizer(potassium sulfate) 10 kg, with 400 kg organic fertilizer applied Per 667m2.
