Treatment of the planting and breeding waste is becoming a big issue due to their significant quantities. Composting could be an effective alternative for planting and breeding waste management which could be used as fertilizer. The purpose of this research was to evaluate the effect of planting and breeding waste on baby cabbage growth and soil properties, to establish a suitable agricultural cycle model for semi-arid area in central Gansu Province. The planting and breeding wastes [sheep manure (SM), tail vegetable (TV), cow manure (CM), mushroom residue (MR) and corn straw (CS)] were used as the raw materials in this study, which were designed 8 compost formulas for composting fermentation. With no fertilization (CK1) and local commercial organic fertilizer (CK2) as the control, the comprehensive evaluation of planting and breeding waste composts on the yield of baby cabbage, fertilizer utilization rate, soil physical and chemical properties and microbial diversity were studied to select the best compost formula suitable for the growth of baby cabbage. And the material flow and energy flow analysis of the circulation model established by the formula were carried out. The results showed that the biological yield and economic yield of baby cabbage, absorption and recycling utilization of total phosphorus (TP) and total potassium (TK) reached the maximum under the formula of SM: TV: MR: CS = 6:2:1:1. Compared with CK2, the formula of SM: TV: MR: CS = 6:2:1:1 significantly increased the richness of soil bacteria and beneficial bacteria Proteobacteria, and decreased the relative abundance of harmful bacteria Olpidiomycota. Principal component analysis showed the comprehensive score of SM: TV: MR: CS = 6:2:1:1 was the best organic compost formula suitable for producing high-quality and high-yield baby cabbage and improving soil environment. Therefore, this formula can be used as a reference organic fertilizer formula for field cultivation of baby cabbage.
种植和养殖废物的处理由于其数量巨大而成为一个大问题。堆肥可以作为种植和养殖废物管理的有效替代方法,可用作肥料。本研究的目的是评估种植和养殖废物对小白菜生长和土壤特性的影响,为甘肃省中部半干旱地区建立适宜的农业循环模式。本研究以羊粪(SM)、尾菜(TV)、牛粪(CM)、菌渣(MR)和玉米秸秆(CS)等种植养殖废弃物为原料,设计了 8 种堆肥发酵配方。以不施肥(CK1)和当地商品有机肥(CK2)为对照,综合评价种植养殖废弃物堆肥对小白菜产量、肥料利用率、土壤理化性质和微生物多样性的影响,筛选出最适合小白菜生长的最佳堆肥配方。并对该配方建立的循环模式进行物质流和能量流分析。结果表明,在 SM:TV:MR:CS=6:2:1:1 配方下,小白菜的生物产量和经济产量、总磷(TP)和总钾(TK)的吸收和循环利用率达到最大值。与 CK2 相比,SM:TV:MR:CS=6:2:1:1 配方显著增加了土壤细菌和有益细菌变形菌门的丰富度,降低了有害菌 Olpidiomycota 的相对丰度。主成分分析表明,SM:TV:MR:CS=6:2:1:1 的综合得分为最适合生产优质高产小白菜和改善土壤环境的最佳有机堆肥配方。因此,该配方可作为小白菜田间栽培的参考有机肥配方。
