【摘要】：本文介绍我国畜禽养殖废弃物还田利用模式发展概况,分析养殖废弃物循环利用产业发展的问题,探讨下一步的发展战略。总结发现,多年来国内外在探索畜禽养殖废弃物还田利用模式、农田适宜载畜量参数等方面取得了重要的进展,但仍然存在种养结合养分不平衡、各种处理过程养分损失大、农田合理施用粪肥原则缺失等问题。下一步的研究应该以"还田利用,环境友好"为目标,引入种养结合粪便养分管理理念,开展畜禽养殖废弃物的收集—贮存—处理—还田;开展包括优化还田安全利用技术、种养循环过程温室气体减排、农田对养殖废弃物合理消纳量定量、减少氮磷养分损失避免面源污染等方面的研究,同时在政策上引导畜禽养殖废弃物的高效资源化利用。
[Abstract]:This paper introduces the wastes of livestock and poultry in China using the development of mode field, analysis of aquaculture waste recycling industry development issues, to explore the development strategy of the next step. Concluded that for many years at home and abroad to explore the livestock and poultry waste field utilization mode, suitable for farmland carrying capacity parameter etc has made important progress, but there are still binding nutrient imbalance in planting, processing nutrient loss, reasonable land application principle. The lack of manure and future research should take "field use, environment friendly" as the goal, combined with the introduction of manure nutrient management concept to carry out planting, livestock and poultry waste collection and storage handling - returning; carry out optimization including returning safety the use of technology, greenhouse gas emission reduction breeding cycle of farmland, livestock waste properly treatment quantity, reduce nitrogen and phosphorus loss to avoid Research on non-point source pollution and so on, at the same time, to guide the efficient and resource utilization of livestock and poultry waste in policy.
