Effect of applying wheat stubble on preservation and utilization of n-fertilizer by {sup 15}N trace technique

Technical Report:

Abstract

By using {sup 15}N trace technique, the effect of applying wheat stubble on the preservation and utilization rate of {sup 15}N- ammonium sulphate have been studied. The abundance of ({sup 15}NH{sub 4}){sub 2}SO{sub 4} fertilizer was 8.92%. After three years pot test and field plot test, the results showed that the yields with `{sup 15}N+mulching` and `{sup 15}N+incorporating` treated were increased by 5.4{approx}30.0% for spring wheat and millet(pot test), and 18{approx}23% for winter wheat and summer corn(field plot test), as compared with only `{sup 15}N` treatment. The results of {sup 15}N-fertilizer labelled tests showed that the utilization rates of {sup 15}N-fertilizer treated by `{sup 15}N+mulching` for cropping seasons were 57.8%, 65.8%, 36.6% and 8.5% respectively. These were increased 3.7%, 10.2%, 21.5% and 2.8% as compared with only `{sup 15}N` treatment. Comparing with only `{sup 15}N`treatment, the N leached off by percolation water was decreasing 50%, the loss of N caused by volatilization was decreasing 30.3% and the N in humus was increasing 21.1%. All of these proved that the applying of wheat stubble in different mode would adjust and control the activation of microbe in the soil, and the preservation and utilization rate of fertilizer in the soul would be  More>>
