Effects of different fertilization patterns of three slow-release fertilizers on wheat yield and economic benefits
In order to understand the application effects of different slow-release fertilizers on wheat production cost saving,yield increase and efficiency increase,and to explore the effects of different fertilization modes on yield and efficiency,the supporting application technologies of different slow-release fertilizers in wheat production in Jiangdu District were studied.The results showed that the slow-release fertilizer had the ability to slow down and control the release of nutrients in wheat production,which could change the traditional habit of multiple fertilization,and the three kinds of slow-release fertilizer were used as basal fertilizer and top dressing for secondary application,and the reasonable ratio could save labor and cost,increase yield and efficiency.Under the premise of equal nitrogen,slow-release fertilizer + urea base application,compound fertilizer + urea booting stage topdressing was more effective than conventional fertilization to increase yield and efficiency,it was not recommended that slow-release fertilizer in wheat production one-time base application,it can save labor,but it can't save cost,due to the long growth period of wheat,the fertilizer effect in the later stage can not be connected,it was easy to lack fertilizer and premature aging,affect the yield.In the appropriate sowing period,the yield and efficiency increase of Hanfeng slow-release fertilizer was the most obvious,and the topdressing treatment of slow-release fertilizer + urea base application and compound fertilizer + urea booting stage was the second in yield and the first in benefit.Under the premise of equal nitrogen content on different sowing dates,the application of slow-release fertilizer and fast-acting urea in the ratio of base fertilizer can significantly reduce costs and improve economic benefits.
