| 摘 要： | 通过田间试验,研究了施用微生物复混肥对盐碱土微生物量、土壤容重、土壤盐分及白菜品质的影响。结果表明,与不施肥、化肥和基质处理相比,白菜收获后施用微生物复混肥处理的土壤细菌总数分别增加了106.04%,58.99%和48.12%;土壤容重分别降低0.05g/cm3,0.03g/cm3和0.02g/cm3。微生物复混肥对降低耕层土壤含盐量有明显作用,但对1m土体土壤平均含盐量影响效果不明显。施用微生物复混肥能改善白菜品质,比不施肥与施化肥分别降低白菜硝酸盐含量0.14mg/kg和1.80mg/kg,可溶性糖量分别提高0.4%和0.8%。

| Abstract: | Field experiments were conducted to research the effects of bio-fertilizer on saline soil bulk density,microorganism amounts,soil saline distribution and Chinese cabbage quality.The results indicated that compared to no fertilizer,fertilizer treatments and base treatment,respectively,mixed microorganism fertilizer could increase soil bacteria amount 106.04%,58.99% and 48.12%,while decreased soil bulk density 0.05 g/cm3,0.03 g/cm3 and 0.02 g/cm3.Mixed microorganism fertilizer could effectively decrease soil salinity in plowing depth,but had little decreased effect on 1 m soil depth.Applying mixed microorganism fertilizer could improved Chinese cabbage quality,which decreased plant Nitrate content by 0.14mg/kg and 1.80mg/kg,while increased soluteable sugar content by 0.4% and 0.8% compared to no fertilizer and fertilizer treatments,respectively. |
