临河区施用狮肥宝试验研究

Study of Shifeibao Application in Linhe District

[目的]通过田间试验,研究狮肥宝在春小麦不同时期上的长效作用。[方法]设6个处理,4次重复,随机区组排列,小区面积40m2。小区与小区之间筑堰埂,开挖灌水毛渠,小区单灌单排,外围设置1.5 m保护行。[结果]与普通尿素相比,狮肥宝在本地有施肥增产的效果,同时节约劳动成本。[结论]狮肥宝的缓释效果较好,能在作物的生长过程中不断释放氮肥,为作物整个生育期提供充足均衡的氮素营养,起到提高肥料利用率、节约肥料用量、增加产量的效果,而且一次性表施,比普通尿素分期追施减少施肥的劳动成本。

[Objective] The research aimed to study the long-acting effects of Shifeibao in different period of spring wheat through the field trial.[Method] 6 treatments were arranged,and 4 repeats were set.Randomized block was adopted.The plot was 40 m2.Weirs were built between the plots,and irrigation sublateral was digged.Single irrigation and single drainage were adopted,and 1.5 m guard row outside was set.[Result] The slow release effects were good,which could release nitrogen fertilizer constantly in the growth of the crop,and provide the adequate and balanced nitrogen in the whole growth period.One-time top application of Shifeibao could reduce the labour cost compared with the top dressing of common urea.[Conclusion] Compared with the common urea,the application of Shifeibao had the effect of the increase of the production and the reduction of the labour cost.
