| Abstract: | 【Objective】This paper focuses on exploring the effect of two chlorinated pyridine nitrification inhibitors under drip irrigation on soil nitrogen transformation and the yield of cotton.【Method】A field experiment was conducted on nitrification inhibitor in cotton drip irrigation in the Agricultural Center.【Result】The two types of tested nitrification inhibitor showed significant inhibitory effect on nitrification six days after they are applied with water drops,the content of soil NH4+-N increased 3.82%-211.25%,NO3——N decreased 56.2%-77.12%,the rate of apparent nitrification decreased 2.66%-52.83 %compared with control treatment,the nitrogen validity increased by 1.54~4.15 percent,the increase of seed cotton yield per hectare is 202.5-247.5 kg,which showed 3.43%-4.3% increase rate,the newly increased economic benefit is 1 059-1 306.5 RMB.【Conclusion】Under drip irrigation,the nitrification inhibitors apply with water drops,which is easy to operate and can effectively improve the N nutrition level of the cotton plants,therefore,the yield increase is significant. |
