猪粪堆肥与化肥配施对水稻产量和氮效率的影响

Effects of Combined Application of Pig Manure Compost and Inorganic Fertilizers on Yield of Rice Grains and Nitrogen Use Efficiency

摘要: 采用大田试验方法研究猪粪堆肥与化肥配施对水稻产量和氮效率的影响。结果表明:在本试验条件下,猪粪堆肥与化肥配施能显著提高水稻籽粒产量,增加水稻每穗实粒数。尤其是1 500 kg.hm^-2猪粪堆肥+化肥配施处理,稻谷产量达8 595 kg.hm^-2,比未施氮处理和化肥处理分别增产57.8%和13.6%,差异达显著水平。猪粪堆肥与化肥配施处理水稻氮素养分效率均高于化肥处理。猪粪堆肥与化肥配施的氮肥回收率为35.3%³8.6%,而化肥处理仅为27.6%。

Abstract: A field experiment was carried to study effect of combined application of pig manure compost(PMC) and inorganic fertilizers(IF) on yield of rice grains and nitrogen use efficiency.Results show that highest yield(8 595 kg·hm^-2) was obtained in Treatment PMC(1 500 kg·hm^-2)+IF,being about 57.8% and 13.6% higher than that in CK and Treatment IF,respectively,while nitrogen recovery rate ranged between 35.3% and 38.6% in all the PMC+IF treatments,but reached only 27.6% in Treatment IF.
