Effect of three furrow openers for no-till wheat seeder on crop growth performance;
小麦免耕播种机开沟器对作物生长的试验研究
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.
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。
The soil load characteristics of the furrow opener of no tillage planter were measured in the soil bin.

As the acute angle styled opener often tends to hang the roots and jam during direct seeding in the corn field with big roots, we adopt a new way which uses the stagger double-disk opener.
针对在玉米根茬较大,田地免耕直播时锐角式开沟器易出现挂茬、堵塞等问题,提出了采用错开双圆盘开沟器的方案。
The soil load characteristics of the no-tillage planter opener were measured in the soil bin.
在土槽上对免耕播种机单体开沟器空间受力特征测定分析表明：在土壤硬度为１６～２６ｋｇ／ｃｍ￣２范围内，开沟器入土阻力为７０～１００ｋｇ，牵引阻力为４５～８０ｋｇ；随工作速度和附加配重的增加，入土阻力和牵引阻力均增大。
