| 摘 要： | 采用田间试验法,在高磷和低磷土壤上分别设置施磷和不施磷处理,研究磷对9个玉米基因型生物量、产量、氮磷钾养分吸收量的影响及其各基因型间的异同,为磷肥合理施用提供科学依据。结果表明,在高磷土壤上,不施磷对各玉米基因型的生物量、产量、产量构成因素和多数玉米基因型的氮磷钾吸收量影响不大;在低磷土壤上,不施磷降低各玉米基因型的生物量、穗粒数、产量及氮磷钾吸收量。两个磷水平下,均以蠡玉16的生物量和产量最大,冀单28最小,这与前者具有较多的养分吸收量有关。不同玉米基因型间有明显差异,在玉米生产中应该因地制宜合理施用磷肥。

| Abstract: | On the higher and lower available P soils,treatments of P fertilizer application were designed in the field condition.Effects of P fertilizer application on the plant biomass,yield,nutrient uptake of N,P and K in nine maize cultivars,and their differences were studied.This provided the scientific basis for P fertilizer reasonable application.The results showed that on the higher available P soil,P fertilizer application hardly influenced the maize biomass,yield and its constitute,and nutrient uptake of N,P ... |
