免耕播种机开沟器的适应性分析

目前,国内外免耕播种机开沟器种类较多,但性能与实际生产要求存在着相当大的差距,表现出适应作物单一、通过性能差、破茬能力弱、对地表破坏率较大、调节困难、使用可靠性及适应性较差等问题。为推广保护性耕作,实施有效免耕播种,以研究开沟器适应性为主题,在不同地表田间对北方地区使用的免耕播种机开沟器进行了试验、测试、分析、研究,对其适应性进行了探讨,认为在实施免耕播种作业时,开沟器必须有较强的破茬和清草能力,需配备切草与清草装置。单纯依靠增加机具的重量来加强开沟器的入土能力,其适应性较差。通过实验可知,采用动力型平面条旋开沟器性能可靠,实现了在土壤硬度较高、含水率较低、土壤板结严重、秸秆覆盖条件下进行免耕开沟作业,其适应性可靠,可以满足免耕播种农艺要求。

Exempts Ploughs the Seeder Furrow Opener the Compatible Analysis

At present,domestic and foreign exempts ploughs the seeder furrow opener type many,but the performance and the actual production request have the quite big disparity,displays the adaption crops solely,passing energy balance,broken stubble ability weak,is bigger to the surface destruction rate,adjustment difficulty,use reliability and compatible more inferior question.In order to promote the protection cultivation implementation effectively to exempt ploughs sowing seeds,take studies the furrow opener compatibility as the subject,exempted in the different surface field to the northern area use ploughs the seeder furrow opener to carry on the experiment,the test,the analysis,the research,carried on to its compatibility has controlled asks for,thought exempted when the implementation ploughed the sowing seeds work,the furrow opener must be supposed to have a stronger broken stubble and the clear grass ability,had to provide cuts the grass and the clear grass installment,the pure dependence increased the machines and tools the weight to strengthen the furrow opener to be buried the ability,its compatibility was worse.May know through the experiment,uses the power even noodles to turn on lathe the furrow opener performance reliably,has realized in the soil degree of hardness high,moisture content lower,the soil hardens seriously,under the straw cover condition carries on exempts ploughs the ditching operation,its compatibility is reliable,may satisfied exempt ploughs the sowing seeds agronomy request.
