大型耕整播种机械节能增效机械化技术模式试验研究

Study on Energy Saving and Efficiency Increasing Mechanization Technology of Large Machinery Tillage and Seeding Operation

我国是农业大国,新时代应以绿色发展引领农业生产。为此,结合玉米秸秆粉碎还田生产需求,在东北松嫩平原齐齐哈尔富拉尔基黑土区进行了深翻、深松、松旋和旋耕4种耕整播种节能增效机械化技术模式试验研究。结果表明:在活动积温和降水较好的碳酸盐黑钙土生境条件下,深翻耕整播种机械化技术模式土壤和产量性状指标表现最优,但节能性能与深松耕整播种机械化技术模式相比差别显著。深松耕整播种机械化技术模式节能表现最优,土壤和产量性状指标表现与深翻耕整播种机械化技术模式相比差别不显著。综合分析表明,深松耕整播种节能增效机械化技术模式优化匹配方法表现最优。

China is a big agricultural country.In the new era,green development should lead agricultural production.In this paper,combined with the production demand of corn straw smashing and returning to the field,four kinds of tillage and seedingenergy saving and efficiency increasing mechanization technology models,deep ploughing,subsoiling,loosening rotation and rotary tillage,were carried out in the Northeast Songnen Plain,Qiqihar Fularji black soil area.Under the condition of carbonate chernozemwith better active accumulated temperature and precipitation,the performance of soil and yield characteristics of deep tillage and whole seeding mechanization technology mode is the best,but the performance of energy saving performance is larger than that of subsoiling tillage and whole seeding mechanization technology mode.The performance of deep tillage and whole seeding mechanization technology mode is the best,and the performance of soil and yield characteristics index is better than that of deep tillage and whole seeding machine Comprehensive analysis shows that the optimal matching performance of energy saving and efficiency increasing of subsoiling tillage and whole seeding mechanization technology mode is the best.Trait indicators.
