| 摘 要： | 目的]研究养殖场粪肥与农田负荷量间的种养平衡。方法]以北京市某种猪场(基础母猪600头,总存栏量647头)为例,研究该猪场粪肥施入后的农田氮平衡。结果]该项目周边农田较适宜的N素施入量为191.9kg/(hm2·年),该猪场实现种养平衡所需的农田面积为53.7hm2。结论]该研究为养殖场的种养平衡提供了一种较为可行的判定方法和思路。

| Abstract: | Objective] The aim was to research balance between manure of breeding farm and farmland load. Method] N balance of farmlands after manure fertilized was researched in a hoggery in Beijing (600 base sows and 647 breeding pigs). Result] The suitable N input in neighboring farmlands was 191.9 kg/(hm 2 ·y) and the farmland area satisfying balance between growing and breeding was 53.7 hm 2 in the hoggery. Conclusion] The research provided a scientific method for balance between growing and breeding. |
