摘要
西南地区以旱地小麦为主,受生产生态条件限制,该区机械化水平低,播种质量差,产量不高不稳。旱地小麦机播技术适应性研究表明,2BJ-2型播种机和2B-4、2B-5型播种机体型小、重量轻,由人力或微耕机驱动,方便在丘陵旱地转运和作业。与传统播种技术稀大窝处理相比,机械播种的效率大幅提高,播种成本降低50%以上,产量提高4.8%~45.0%。小型播种机尤其是2B-4、2B-5型播种机在西南丘陵旱地有很好的适应性。
The wheat in the Southwest of China,mainly distributes in dry land in hilly region.Because of the limitation of ecological condition,the mechanization level of wheat production in this region is low,and the sowing quality is poor.Study of adaptabitity of wheat mechanical sowing technique in dry land in sounthwest region was conducted.The research showed that small seeders such as 2BJ-2,2B-4 and 2B-5 type seeder driven by human or micro-cultivator had light weight,were easily transited and operated.Compared with the conventional sowing technique,the sowing efficiency of mechanical sowing technique improved significantly,and the sowing cost decreased by more than 50%,and the yield increased by 4.8% to 45.0%.Small seeders especially 2B-4,2B-5 type had good adaptability in dry land in southwest region.
