摘要:

本研究通过对有单排单灌的12个甘蔗旱地小区进行4种不同的施肥条件处理,分析不同施肥处理下甘蔗生长期内降雨产生径流中氮磷的含量。结果表明:径流总氮和总磷在CK条件下一直处于较低水平;从长期趋势来看,径流中总氮含量大小依次为:CT>BS >NSPC-BS;径流中总磷含量大小依次为:CT>NSPC-BS>BS。径流中总氮流失负荷依次为:NSPC-BS<BS<CT,径流中总磷流失负荷依次为:BS<NSPC-BS<CT。

Abstract:

In this study, four different fertilization treatments were conducted in 12 dry sugarcane plots with single row and single irrigation to detect the nitrogen and phosphorus content of runoff water generated by natural rainfall during the growth period of sugarcane under 4 fertilization schemes. The results showed that: Total nitrogen and total phosphorus in CK runoff were always at a low level; From the long-term trend, the content of TN in runoff showed as CT>BS>NSPC-BS; Total phosphorus content in runoff water showed as CT>NSPC-BS>BS. Total nitrogen loss load in runoff showed as NSPC-BS<; total phosphorus loss load in runoff BS<NSPC-BS<CT.

Key words: sugarcane, runoff, nitrogen, phosphorus, organic fertilizer
