摘要

为了阐明在东北高寒区连年施用沼渣对玉米产量、效益和土壤肥力的影响，于2013年5月至2014年10月在黑龙江省海林市海林农场的玉米试验田进行了沼渣和化肥配施的田间试验。结果表明：连续2年的施用沼渣以及沼渣与化肥配施均能够增加玉米产量，而施用45 000 kg/hm2的沼渣增产幅度最大，全量施用600 kg/hm2化肥的玉米产量小幅减少。施用1 t沼渣可替代135.25 kg尿素、180.18 kg磷酸二铵和107.09 kg硫酸钾，产生956.72元的直接经济效益。施用沼渣的各处理与不施肥处理相比，经济效益均显著增加，7 500 kg/hm2沼渣+450 kg/hm2化肥的处理经济效益最高，平均可达到18 066.2元/hm2。沼渣单施及与化肥配施后表层土壤pH可提高0.02～0.28个单位，有机质可增加0.14～2.84 g/kg，可在一定程度上增加表层土壤中养分的含量。因此，在东北高寒区实际生产中可以考虑合理的配施沼渣替代化肥，实现对沼渣的高效化和经济化的利用。

Abstract

To clarify the effective mechanism of applying biogas residue on the yield

the benefit and soil fertility of maize for two consecutive years

we conducted a field experiment in Hailin farm

Hailin City

Heilongjiang Province. From May 2013 to October 2014

treatments of the single biogas residues

the mixtures of biogas residues and chemical fertilizers

full dose of chemical fertilizers were applied to the test field of maize. The results showed that both applications of the biogas residues and the mixtures of biogas residues and chemical fertilizers for two consecutive years could increase the yield of maize. More specifically

the application of biogas residues at 45 000 kilogram per hectare increased the yield of maize the most significantly. However

the full dose of chemical fertilizer application at 600 kilogram per hectare slightly decreased the yield of maize. The application of biogas residue at one ton could substitute 135.25 kilogram carbamide

180.18 kilogram diammonium phosphate

and 107.09 kilogram potassium sulfate. As a result

it generated a direct economic benefit of 956.72 yuan. Application of biogas residues achieved significant more economic benefits compared with the control. Application of the mixtures of biogas residues at 7 500 kilogram per hectare and chemical fertilizers at 450 kilogram per hectare exhibited the highest economic benefits

and its average economic benefit was 18 066.2 yuan per hectare. The pH values could be increased by 0.02 to 0.28 units and the organic matter could be increased by 0.14 g/kg to 2.84 g/kg in the surface layer of soil after the single application of biogas residue

and the mixed application of biogas residues and chemical fertilizers. Nutrient contents of the surface layer of soil were also increased to some degrss. Therefore

the reasonable application of biogas residues in the practical production may replace the application of chemical fertilizers to realize the efficient and economic utilization of the biogas residue in the cold high-latitude area of the northeast China.
