砂姜黑土是黄淮海平原三大中低产土壤之一,研究砂姜黑土区农田土壤障碍因子消减技术,对于砂姜黑土改良和提升该区耕地粮食生产力具有重要意义。在分析砂姜黑土农业利用障碍因子的基础上,详细阐述了消减这些障碍因子的技术措施:适当控水;起垄种植;改进耕作,调控土壤水分状况,防止土壤发生旱涝危害;添加外来物质改性;科学合理施肥,推广测土配方技术;建立农田防护体系等。
Shajiang black soil is one of the three middle and low-yielding soils in the Huang-Huai-Hai Plain. Studying on the reduction of farmland soil obstruction factors in the Shajiang black soil area is of great significance for the improvement of the Shajiang black soil and the improvement of grain productivity in the arable land. Based on the analysis of the barriers to agricultural utilization of Shajiang black soil, the technical measures to reduce these barriers were elaborated: proper control of water, ridge planting, improvement of tillage, regulation of soil moisture status, prevention of soil drought and flood damage, addition of foreign substances Modification; scientific and rational fertilization, promotion of soil testing and formulating technology; establishment of farmland protection system.
