兔类尿和硫酸铵交叉标记法盆栽试验结果表明:兔粪尿是含有大量有效性养分的有机肥料,增产效果相当于等氮量硫铵。水稻对兔粪尿氮利用率为31%~42%,在无机氮肥配合下利用率较高;硫酸铵作基肥的利用率为48%,作追肥的为51%~58%。生长早期,土壤供氮能力较差的水稻植株对基肥利用率高。兔粪尿氮在土壤中残留率为44%~53%,硫铵作基肥的残留率为36%左右,作追肥的为19%~26%。
Rabbit urine and ammonium sulfate cross-labeling method potted test results show that: Rabbit excrement is a large amount of organic fertilizer containing effective nutrients, the equivalent yield of nitrogen and ammonium sulfate. Urea nitrogen utilization rate of rice was 31% ~ 42% for rabbit manure, which was higher under the combination of inorganic nitrogen fertilizers. The utilization rate of ammonium sulfate as basal fertilizer was 48% and topdressing was 51% ~ 58%. In the early stage of growth, rice plants with poor soil nitrogen-supplying capacity have high utilization rate of basal fertilizer. Rabbit excretion of urine nitrogen in the soil of 44% to 53%, ammonium sulfate as a base of about 36% of the residue, top dressing for 19% to 26%.
