Different Nitrogen Fertilization On The Yield And Qualities Of Radish Grown In Weixian

This experiments was carried out from july 2004 to november 2005 at shandong weifang technic college experiment site on Weixian radish. The effects of Studied ammonium nitrate, ammonium bicarbonate and urea nitrogen in three different fertilization volume of Weixian radish production, nutrition and quality of nitrate and nitrite content. The main results were as follows:1. Weixian radish leaf size shape had a significantly positive correlation with fertilization volumes. There were no significant difference that the impact of different types of nitrogen fertilizer on Weixian radish formation of leaf area.2. Weixian radish production volume are not positrively associated with fertilization; Weixian radish different types and the optimal nitrogen fertilization of different. In the context of a nitrogen consumption increased Shi Wei Xian radish conducive to improving the production of nitrogen fertilizer, but it will reduce production on the excessive use of nitrogen fertilizer.Ammonium nitrate more conducive to the formation of Weixian radish production, Weixian radish production, the choice of different types of nitrogen fertilizer used in the most different, Ammonium nitrate and urea to 300kg Chundan /hm2 appropriate, and ammonium bicarbonate is 450kg Chundan /hm2 appropriate.3. The nitrate content Weixian radish volumes are associated with fertilization, and nitrite concentration and fertilization capacity is not relevant. nitrogen fertilizer processing three to Weixian radish roots, Weixian radish roots, nitrate texture of the impact of the size of the order for the content...
