潢川县萝卜“2+X”肥效对比试验研究
"2+X" Fertilizer Controlled Test Research of Radish in Huangchuan County
摘要
Abstract
In order to optimize the radish fertilizer in Huangchuan region and determine the appropriate application,allocation and application of fertilizer.In this experiment,we set"Nentouqing"carrot as material,and"2+X"dynamic optimization of fertilization as manages.The result showed that in the range of 63.2~180.0 kg/hm2,Nitrogen fertilizer play a optimistic role in promoting on radish seedling growth and development.Different treatments of Nitrogen ratio can significantly improve the yield of radish,and shows the same trends that with the increasing use of Nitrogen amount,the yield increased,and then decreased. Wherein the treatment of Nitrogen slow-release fertilizer was the highest treatment yield was 29 133.33 kg/hm2,which was increasing production 3 866.66 kg/hm2,an increasing rate of 15.30% of same Nitrogen fertilization.It was not significant among treatments of optimistic Nitrogen+boric fertilizer,normal fertilizer and optimistic Nitrogen.However,the treatment of Nitrogen slow-release fertilizer reduced of fertilizer 2 times for application,saved the labor costs 900.00 yuan/hm2,increased economic efficiency 28.46% than normal treatment,and 19.34%compared to optimizing nitrogen treatment.According to the result of curve of radish average output and applying Nitrogen content effect,when the pure Nitrogen application is 150.7 kg/hm2,the yield reached 23 791.0 kg/hm2,which is the maximum yield. As a result,the optimum fertilizer treatment was slow-release fertilizer,which showed highest yield and the best economic benefits,and the trial provides a scientific basis for the high yield,efficient,environmental protection and light simplified fertilization of radish.关键词
