| 摘 要： | 通过盆栽试验,研究了肥料与石膏配合施用对滨海盐土油菜生长及养分吸收的影响,探讨了滨海盐土适宜的肥料品种。结果表明,肥料与石膏配合施用对滨海油菜生长有显著影响,在油菜干物质累积、油菜产量上均以有机无机复混肥、生物有机肥配合无机复混肥配施石膏效果最好。供试肥料品种间,油菜生长中后期在干物质累积、产量上均表现出有机无机复混肥(F2)、生物有机肥配合无机复混肥(F4)>无机复混肥(F1)>生物有机肥(F3)>对照,各肥料较对照分别增产195.6%、190.9%、117.0%和53.4%。在有机无机复混肥、生物有机肥配合无机复混肥的基础上增加石膏的施用量可明显改善油菜生长状况和产量,但在无机复混肥基础上增加石膏施用量会导致油菜干物质累积和产量的明显降低。肥料与石膏配合施用影响油菜对N、P、K养分的吸收,在油菜苗期养分吸收上,N、K以无机复混肥(F1)较高,P以有机无机复混肥(F2)较高,施用石膏可促进油菜对N、K的吸收,但会显著降低对P的吸收量。滨海盐土地区油菜栽培以有机无机复混肥(F2)、生物有机肥配合无机复混肥(F4)配合石膏(B2)施用较为适宜。

| Abstract: | The effects of fertilizer with gypsum application on growing development and nutrients uptake of rape with the pot experiments in coastal saline soil were studied.The appropriate fertilizer varieties were discussed.The results were as follows: there were significant effects in fertilizer and gypsum application on rape growth in coastal saline soil.The dry matter accumulation and rapeseed yield in treatments of organic-inorganic fertilizer or bio-organic fertilizer and inorganic compound fertilizer with gypsum were the best.During rapeseed growth period and among the tested fertilizer varieties,the order of the dry matter accumulation and yield of rape was organic-inorganic compound fertilizers(F2),bio-organic fertilizer and inorganic compound fertilizer(F4)> inorganic compound fertilizer(F1) > bio-organic fertilizer(F3) >the control.The rape yield of each fertilizer increased 195.6%、190.9%、117.0% and 53.4% than that of the control,respectively.The application of gypsum with organic-inorganic compound fertilizer,bio-organic fertilizer and inorganic compound fertilizer could significantly improve the growth and yield of rape.But the application of gypsum with inorganic compound fertilizer could significantly decrease the dry matter accumulation and yield of rape in coastal saline soil.There were significant effects of fertilizer with gypsum application on the nutrient uptake of rape in coastal saline soil.The N and K uptake in inorganic compound fertilizer(F1) was higher,and the P uptake in organic-inorganic compound fertilizers(F2) was higher in the nutrient uptake of rape in seeding stage.The application of gypsum could improve the N and K uptake of rape in coastal saline soil,but could significantly decrease the P uptake.The appropriate fertilizer variety during rape cultivation was organic-inorganic fertilizer(F2) or bio-organic fertilizer and inorganic compound fertilizer(F4) with gypsum(B2) application in coastal saline soil. |
