    摘要:

    針對(duì)我國(guó)西北綠洲農(nóng)業(yè)區(qū)現(xiàn)有固定壟免耕播種機(jī)種類少，且在玉米秸稈地固定壟免耕播種小麥易堵塞、破壞壟形等問題，提出了動(dòng)力甩刀碎、拋茬和刀刃型開溝器破茬結(jié)合防堵及雙翼型犁鏵修壟的方法。設(shè)計(jì)了動(dòng)力甩刀破茬式小麥固定壟免耕播種機(jī)，并確定了L型甩刀、開溝器、雙翼型犁鏵等關(guān)鍵部件的參數(shù)。在玉米秸稈覆蓋地試驗(yàn)結(jié)果表明，動(dòng)力甩刀破茬式小麥固定壟免耕播種機(jī)能有效地解決秸稈堵塞問題，具有較強(qiáng)的防堵能力；該機(jī)在減少動(dòng)土量的情況下，其產(chǎn)量與2BMF-5型固定壟免耕播種機(jī)基本持平，且修壟效果更好。

    Abstract:

    According to the problems of few available no-till seeders and residues-blocking and bed-damaging during the seeding of wheat in maize residues cover fields in permanent raised beds (PRB) in northwest oasis farming areas, the new anti-blocking (residue-chopping and throwing by powered L-type hammering blade and residue-cutting by knife type opener) and bed renovation (bed-reshaping by double-wing plough) ideas were put forward. The powered hammering blade no-till wheat seeder for PRB was designed. The key parameters for L-type hammering blade, opener and double-wing plough were determined. The experiment in maize residue cover fields showed that the seeder was effective in solving residues blocking. Compared with 2BMF-5 no-till wheat seeder, the spring wheat yield was similar and bed renovation effect was better with the decreased soil disturbance. 
