| 摘 要： | 将无机化肥、有机肥和微生物生物肥作底肥施入种植冬小麦的土壤,并在作物生长发育不同时期,测定微生物生物量碳(Bc)、速效 N,P,K 含量。研究发现各施肥处理之间 Bc 没有显著差异,而土壤无机氮(NH_4~+-N 和 NO_~--N)含量大幅度增加,尤其是施用化肥的小区,在整个冬季,土壤都保持很高的 NH_4~+-N 水平(比施用生物肥的土壤,高出30mg·kg~(-1)以上),极易造成氨的挥发损失。施肥也大幅度提高土壤速效磷含量,尤其生物肥处理,土壤速效磷含量比其他肥料处理要高10mg·kg~(-1)左右,但施肥对土壤速效钾的含量没有显著地影响。施肥各处理的小麦产量比不施肥处理略有增加,但没有达到统计学的显著水平。

| Abstract: | Different fertilizers(mineral,organic and microbiological fertilizer)are used as a base fertilizer on winter wheat field.Soil samples are collected during growth stage of winter wheat,Microbial biomass carbon and available N,P and K are measured.It is found that there is no significant difference of biomass carbon among the fertilizer treat- ments.Inorganic nitrogen content is largely increased in the fertilizer treatments.In par- ticular,the soil used mineral fertilizer contains much higher ammonium than t... |
