摘要
通过深翻深松 ,使耕层达到 30cm左右 ,有利于甜菜块根膨大生长 ,并使根腐病发病率降低 2 2 6 %。利用限深轮 ,使甜菜播种深度控制在 3cm为宜。按 7cm、1 2cm和 1 7cm分层施肥 ,能提高肥料利用率。苗期行间深松 2 5cm以上 ,可大大促进幼苗生长。机械起甜菜的机具入土深度以 30cm为宜。采用本项农机农艺配套技术 ,可使每亩增加 0 81t甜菜 ,单产提高 38 9% ,并使块根含糖率增加 0 6 8°S。
This paper adopts a new method which is combined agronomy with agricultural implements.It can increase sugarbeet yield 0.81t per mu,and root sugar content increases 0.68°S. The method has 3 characters.Firstly,it adopts deep ploughing and subtillage technics.The plough depth is 30cm,which is good for sugarbeet root enlarged growth and decreases root rot 22.6%.Secondly,it utilizes special agricultural implements that can control the sowing seeds depth,as well as manuring layer by layer with 7cm,12cm and 17cm respectively.The fertilizer efficiency was increased.Thirdly,agricultural implement plugs down soil 30cm depth while harvesting beet root.
