- W2381450787 abstract "Considering the facts of the low benefit and nitrogen utilization efficiency for stagger-season vegetables in arid and cold regions,screening out the safe and efficient controlledrelease nitrogenous fertilizers suitable to Bashang region,Hebei,China,is the key technology to improve the quality and effectiveness of stagger-season vegetable and reduce agricultural area pollution.Field and lab experiments in Shangyi were carried out and conducted to study the effects of different controlled release nitrogenous fertilizers on the yield,economical benefit and soil nitrogen.The results showed that the yield reached the maximum 116 362.96kg/hm2 for the stable compound fertilizer of Shikefeng(16-8-18),which was increased by 63.82%and8.43%than that of no fertilizer and compound fertilizer treatments.According to the local traditional economic benefits package price calculation,the economic benefit reached the maximum 18 299.9yuan/hm2 for the coated film of controlled release fertilizers of Shikefeng(22-9-11)with the highest VCR 1.7.According to the weight computation,the economic benefit reached the maximum 79 638.2 yuan/hm2 for the stable controlled release fertilizers of Shikefeng(16-8-18)with the most VCR 4.2.Compared with other fertilizes,stable controlled release fertilizers of Shikefeng(16-8-18)leaded to a maximum of soil total N and alkali-hydrolyzable N,and a minimum of NO3-N content which is environmentally friendly.So,it is recommended for local radish farmers to use controlled release fertilizers of Shikefeng(16-8-18),and convert the local traditional economic benefits package price calculation to the weight computation for selling their products.This research also provides scientific basis for energy efficiency and increasing nitrogen-utilized for controlled release nitrogenous fertilizers to staggerseason white radish." @default.
