摘要: 以华北平原广泛分布的潮土为研究对象,采用室内模拟和室外淋溶试验,通过比较生物有机肥(BOF)、普通有机肥(OF)、沼液(BS)、猪场废水(WLF)、化学肥料(CF)和不施肥(NOP)6个施肥处理对土壤磷淋失量、土壤速效磷含量及小白菜产量的影响,以明确不同肥料施用后土壤磷的转化及淋失能力的差异。结果表明:(1)由于下层土壤对从上层淋溶下的磷的吸附作用,模拟淋溶及室外淋溶实验中各处理组之间磷淋失量差异性不一致,淋失量平均值最大的分别为CF及WLF组。(2)不同肥料处理组在不同土壤深度中速效磷(Olsen-P)含量存在差异,与NOP组相比,CF处理组在0?20cm、BOF处理组在0?60cm深度土壤的Olsen-P含量显著增加,其余处理组与NOP组在4个深度土壤中均无显著差异。(3)在室外淋溶实验中,CF组小白菜产量比施有机肥组高17.8%~82.0%,比NOP组高923.5%,施有机肥组的产量比NOP组高462.4%~768.7%;各组之间植株磷吸收量均存在显著差异,CF组磷吸收量比施有机肥组高22.0%~124.7%,比NOP组高1504.3%,施有机肥组磷吸收量比NOP组高614.0%~1214.9%。综合实验结果可知,从控制磷淋失量、促进植物生长及磷吸收的角度看,BOF和OF是最适合粪污处置的应用方式。

Abstract: Simulate and outdoor leaching experiments were conducted with fluvo-aquic soil in order to clarify the differences on transformation of phosphorus and leaching progress with different resource products from pig manure. The amount of phosphorus leach-loss, Olsen-P content in soil and yields of Chinese cabbage were all determined in the experiments. The treatments included biological organic fertilizer (BOF), ordinary organic fertilizer (OF), biogas slurry (BS), waste-water from livestock farm (WLF), with chemical fertilizer (CF) and no P application (NOP) as control. The results showed that, (1) due to the reason that soil in lower layer can absorb P leached from soil in upper layer, TP leaching amount of simulate and outdoor leaching experiments showed different trends, and the maximum average amount was from treatment with CF and WLF, respectively. (2) There were significant differences on Olsen-P content in different soil depths with different treatments. Compared with NOP treatment, there was a significant increase of Olsen-P content in 0-20cm soil with CF treatment and in 0-60cm soil with BOF treatment. However, there was no significant difference between NOP and other treatments on Olsen-P content in all the four soil depths, respectively. (3) As for the outdoor leaching experiment, the yield of the Chinese cabbage with CF treatment was 17.8%-82.0% higher than the treatments with organic fertilizers, and 923.5% higher than NOP treatment. Moreover, the yields of the Chinese cabbage with organic treatments were 462.4%-768.7% higher than NOP treatment. There were significant differences on the P content in vegetable among different treatments. The content of P in vegetable of CF treatment was 22.0%-124.7% higher than treatments with organic fertilizers , and 1504.3% higher than NOP treatment, moreover, P in vegetable of treatments with organic fertilizers were 614.0%-1214.9% higher than NOP treatment. Above all, it was pointed out that, the most appropriate approach to deal with pig manure were BOF and OF, according to the comprehensive analysis of phosphorus-leaching control, vegetable growth acceleration and phosphorus up-taking ability.
