- 摘要:
- 针对黑龙江省松嫩平原西部干旱、土壤保墒能力差、种植密度偏低、生产成本高等影响玉米生产的主要问题,在开展扩垄增密技术、肥料管理技术、生物防治技术、水分管理技术、土壤保墒技术和机械化粒收技术研究的基础上,构建玉米丰产增效栽培模式。结果表明:与当地普遍采用的玉米生产模式相比,丰产增效栽培模式水分利用效率提高0.95%;磷肥、钾肥的表观利用率(ARE)和肥料农学利用率(AE)分别提高48.61%和6.26 kg?kg-1,56.72%和8.28 kg?kg-1;热量资源利用效率提高0.95%;产量提高92 kg?hm-2,增产0.95%,累计增加经济效益1 501元?hm-2。
- Abstract:
- Aiming at the main problems of maize production involving climate drought,poor soil water storage conservation,low planting density and high production cost in the Western Songnen Plain of Heilongjiang Province,based on the key cultivation techniques including ridge expansion and density increase,fertilizer management,biological control,water management,soil moisture conservation and mechanized grain harvesting,the cultivation technology model of maize high yield and efficient was builded.The results showed that water utilization efficiency of maize high yield and efficient cultivation model increased 0.95%,phosphate and potassium apparent recovery efficiency and agronomic efficiency enhanced 48.61% and 6.26 kg?kg-1,56.72% and 8.28 kg?kg-1 respectively,heat resource utilization efficiency increased 0.95%,yield and benefits enhanced 92 kg?hm-2(0.95%) and 1 501 yuan?hm-2 compared with locally adopted maize production model.
