摘要:
采煤塌陷土地复垦是补充耕地资源的有效途径之一,然而土壤磷有效性低是限制矿区土地复垦和作物生产的重要因子之一。针对施用有机肥对矿区复垦土壤中磷的有效性变化尚不明确的科学问题,本试验采用基于作物磷素需求的有机肥施肥模式,进行采煤塌陷复垦土壤(山西省孝义市偏城村)田间试验,分析连续两年施用相同磷量(100 kg/ hm2 P )的鸡粪、猪粪、牛粪和化肥对玉米产量和磷肥利用效率的影响。结果表明:(1)有机肥处理显著提高了玉米的籽粒产量和地上部生物量。施肥第一年鸡粪处理增产效果显著高于猪粪和牛粪处理,第二年各施肥处理间差异不显著。玉米产量增加主要是提高了百粒重。(2)各施肥处理0-60 cm土壤剖面Olsen-P含量随土层深度增加呈下降趋势。其中0-20 cm土层Olsen-P含量鸡粪处理显著高于猪粪和牛粪处理,20-40 cm土层鸡粪和猪粪处理显著高于牛粪处理,40-60 cm土层处理间差异不显著。(3)连续两年施用有机肥及化肥对玉米磷肥利用效率为:鸡粪≥猪粪≈牛粪≈化肥。施鸡粪处理磷肥回收率最高,2017年和2018年分别为23.97%和26.99%。鸡粪处理农学磷有效性系数最高(1.47),明显高于猪粪处理(1.00)和牛粪处理(0.89)。总之,施用鸡粪显著提高了玉米产量和磷肥利用效率,可作为培肥矿区复垦土壤或与本试验土壤类型相似的低产农田改良的推荐有机肥。
Abstract:
Low phosphorus (P) availability is one of the major limiting factors for mine land reclamation which is one of the effective ways to increase cultivated land resource. For the focus on scientific issues that mechanism of phosphorus availability changing is unclear, the experiment based on crop phosphorus requirement (100 kg/hm2 P) was conducted to study effects of applying chicken manure, pig manure, cattle manure and chemical fertilizer on corn yield, yield component and phosphorus utilization efficiency in coal mining subsidence (located in village Pian cheng, city Xiao yi, province Shanxi) in two continuous years. The results showed that: (1) Corn yield and aboveground biomass were significantly increased by manure application and the yield increase was mainly due to the increase in 100-kernel weight of corn. The yield of chicken manure treatment was significantly higher than that of pig manure and cow manure in the first year, but there was no significant difference in second year.(2) Olsen-P content gradually declined with the increase of soil depth in 0 -60 cm soil layer, Olsen-P content for chicken manure was significantly higher than pig manure and cow manure in 0-20 cm soil layer, that of chicken manure and pig manure was significantly higher than cow manure in 20-40 cm soil layer, but there was no significant difference in 40-60 cm soil layer.(3) The phosphate utilization efficiency is as follows chicken manure ≥pig manure≈cow manure≈chemical fertilizer in two continuous years. Chicken manure treatment has the highest phosphorus recovery rate, respectively 23.97% in 2017 and 26.99% in 2018, and agronomy phosphorus availability coefficient (1.47) which is significantly higher than pig manure (1.00) and cow manure (0.89).In summary, the chicken manure treatment can significantly increase corn yield and the phosphorus utilization efficiency and be used as a recommended fertilization treatment for reclaimed soil in a coal mining subsidence or low-yield farmland similar to the soil type in this experiment.
