Abstract:
To study the effect of fertilization on growth and nodulation of soybean, the experiment analyzed the root phenotype and nodulation of soybean, grown in long-term fertilization trail of Hailun station, CAS. We selected five fertilizers, including NPK, NPKM, NK, NP and PK to research their function on soybean root growth and nodulation. Results indicated that root length, surface and volume showed similar changing trend among different fertilization treatments, and reached peak at podding stage. There were larger root length and root surface in NPK and NP than other treatments. However, average root diameter was the largest in NPKM. Root dry biomass changed as a single peak trend, and there was no significant difference among fertilization treatments. From 5th leaf stage to filling stage, the ratio of root to shoot in CK and PK were lower than NPK, the ratio up to largest value, which was different among treatments before filling period. All these suggested that nitrogen promoted soybean root growth. Otherwise, the nodule number and weight were lower in NK, and higher in PK than other treatments. Those recults indicated that sufficient nitrogen application such as NK, inhibited nodule primordium developed to nodule and nodule growth.
