摘  要:
为揭示沼液配方肥的肥效特点,采用等养分原则和盆栽试验方法,以空白CK为对照,对比研究了追施沼液配方肥和无机复混肥的肥效特点及其对油菜硝酸盐含量的影响。结果表明:沼液配方肥的肥效明显优于无机复混肥,可使油菜鲜重最高增加28.44%,使硝酸盐含量降低5.61%~17.42%,可显著降低碱性土壤pH值,使之趋于中性。同时沼液配方肥使EC值分别降低了5.82%,6.77%,8.58%和10.20%,土壤养分含量碱解氮、速效钾和速效磷最高分别增加到79.45,161.93,72.70mg/kg。

摘  要:
A pot experiment was conducted in this study to compare the effects of applying biogas slurry-based and inorganic compound fertilizers on the biomass and nitrate of rape with equivalent nutrient principles.The results shows that,in contrast to the application of inorganic compound fertilizer,the highest increase of the fresh rape biomass with applying biogas slurry based fertilizer was 28.44%,and the rape nitrate contents of different treatments were reduced by 5.61%~17.42%;furthermore,the soil pH values were also significantly decreased close to neutral and the soil EC values were decreased by 5.82%,6.77%,8.58% and 10.20%,respectively.Meanwhile,the highest increases of the soil alkali-hydrolyzable nitrogen,avail-able P and available K were 79.45,161.93,72.70 mg/kg,respectively.In summary,the biogas slurry-based fertilizer has better impacts on the biomass and nitrate of rape than the inorganic compound fertilizers.
