- 摘要:
- 通过对玉米密植栽培技术、机械深松少耕技术、机械深施肥技术和秸秆还田技术等进行综合组装集成，在黑龙江省双城市3个试验点，推广示范玉米密植高产高效栽培技术模式，2010年核心示范面积6 hm2，示范面积60 hm2，辐射带动6 000 hm2，产量较农户模式增产2 926 kg·hm-2，差异达极显著水平，共节本增效0.27亿元。
- Abstract:
- According to the technological assemble of close planting,subsoiling and fewer-tillage,deep apply fertilizer and straw returned,promotion and demonstration in close planting high yield and high efficiency was formed in 3 trial points of Harbin.In 2010,the area of core demonstration accumulation reached 6 hm2,the area of demonstration accumulation reached 60 hm2,radicalization area of maize production achieved 6 000 hm2.Compared with the farmers’ mode,it could increase yield 2 926 kg·hm-2，the difference was significant,and could reduce cost and increase benefit 0.27 billion yuan per year.
