新疆无霜期短 ,为了实现一年两熟 ,改变传统的耕播方式 ,从而研制出 2 BCM- 6型茬地免耕播种机 ,实现了新疆麦茬地免耕覆盖播种油葵。主要介绍该机的组成、工作原理、主要部件设计 ,并对田间试验进行了研究分析。试验结果表明 :该机平均每穴粒数为 1.6 9粒 ,合格指数大于 98.7% ;穴长在 1～ 3cm内的占 99.3%以上 ;整机平均粒距为 19cm,变异系数小于 19.6 % ,粒距合格指数大于 94.9% ,重播指数小于 1.8% ,漏播指数小于 2 .9%。该机各项性能指标达到设计要求 ,并且较为稳定 ,工作可靠性较高。与传统耕播相比 ,可抢时播种 ,减少水分蒸发 ,减少径流 ,增加土壤的蓄水、保墒能力 ,作业质量完全满足新疆复播油葵的农艺要求 Xinjiang frost-free period is short, in order to achieve two crops a year, changing the traditional farming methods, so as to develop 2 BCM-6 stubble no-tillage planter, wheat planting in Xinjiang to achieve no-tillage coverage of oil sunflower. Mainly introduces the composition of the aircraft, working principle, the main components of the design, and field experiments conducted a research analysis. The results showed that the average grain number per grain was 1.6 9, the pass index was more than 98.7%, the hole length was above 99.3% within 1 ~ 3cm, the average grain distance was 19cm, the coefficient of variation was less than 19.6% The passing index is greater than 94.9%, the replay index is less than 1.8% and the leakage index is less than 2.9%. The aircraft performance indicators meet the design requirements, and more stable, high reliability. Compared with the traditional farming, sowing time to grab, reduce evaporation, reduce runoff, increase soil water, soil moisture retention capacity, quality of work fully meet the sunflower sowing in Xinjiang agronomic requirements
