摘要

A study was undertaken to evaluate the effect of fertilizers and organic manures (biogas slurry, green manure, sulphitation pressmud and sugarcane trash) on the amount and distribution of nitrogen (N) fractions in soil. After 17lh crop cycles of sugarcane based cropping system, application of fertilizers alone and in combination with organic manures significantly increased all the forms of N except N03"-N over control (N50P100K]00). Among the various N fractions non-hydrolysable N was the dominant Nfraction. The highest values of these fractions were found in T4 (100% NPK + 20 t ha~(-1) biogas slurry). The relative contents of these fractions were in order : non-hydrolysable N > amino acid-N > unidentified-N > hydrolysable NH/-N > exchangeable NH_4~+-N > hexoseamine-N > NO_3~--N. All the fractions except NO_3~-N were in dynamic equilibrium as indicated by significant and positive correlation (r = 0.861** to 0.977**) among them. The per cent distribution of soil N into different N fractions variedfrom 2.15 to 3.24 per cent as NO_3~--N, 11.4 to 15.6 per cent exchangeable NH/-N, 4.54 to 5.37 per cent hexoseamine-N, 18.6 to 20.8 per cent amino acid-N and 13.3 to 14.3 per cent in unidentified form of N. Correlation studies between plant parameters ofsugarcane and soil N fractions indicated that the yield of sugarcane as well as sugar yield and uptake of N, P, K, S and Zn by sugarcane were significantly and positively correlated with all N fractions except N03"-N.

Co中含有50％的己糖胺-N，18.6％至20.8％的氨基酸-N和13.3至14.3％甘蔗糖的植物参数与土壤氮组分之间的相关性研究表明，除N03“ -N外，甘蔗的产量以及甘蔗的糖产量和对氮，磷，钾，硫和锌的吸收与所有氮组分均呈显着正相关。
