Abstract:

In order to improve the fertilizer utilization ratio, to improve and enhance QuanFei one-time fertilization techniques, the corn application SRFS technical support in layered fertilization, one-time base fertilizer, according to the whole growth period of corn, not the growth, development and yield and influence factors of yield components. The results showed that: the use of sulfur slow-releasing function and coating urea fertilizer, using disposable layered base to meet the whole growth period of corn, plant nutrients needed than conventional staging decent, fertilizer production 12.1%. This method broke the traditional pattern of conventional staging fertilization, reduced the surface application caused by volatile loss, improved the Fertilizer utilization ratio reached more than 70 percent, increased production, reduced the production processes to achieve cost saving time save work, which could increase the purpose of pure economic benefit about 1600 yuan/hm2.
