液体肥施用对滴灌棉田土壤无机氮素转化的影响
Effect of Liquid Fertilizer Application on Soil Inorganic Nitrogen Transformation in Drip Irrigation Cotton Fields
摘要
Abstract
To address the bottleneck in improving nitrogen fertilizer utilization efficiency,this study investigates the effects of liquid fertilizer compared to conventional fertilizer on inorganic nitrogen transformation in drip-irrigated cotton fields.This study was conducted in 2022 across eight regions of northern Xinjiang,including Fangqun Farm,Lanzhou Bay in Manas County,Laolong River in Changji,Hongliutang Village,Hongshan Village in Hutubi,Yushugou in Changji,Sangonghe Township in Fu-kang,and Liuhe Canal in Fukang.Three treatments were set up:conventional fertilization,liquid fertil-izer,liquid fertilizer with 10％water reduction.The findings were as follows:across all regions,the content of nitrate and ammonium nitrogen in the soil layers of 0-30 cm and 30-60 cm was as fol-lows:10％water reduction+liquid fertilizer＞liquid fertilizer＞conventional fertilization;regardless of the region,the content of nitrate and ammonium nitrogen in the soil below the emitter was signifi-cantly higher than that at 38 cm or-38 cm from the emitter;the nutrient input of liquid fertilizers per unit area decreased by 19.4 kg/667m2 compared to conventional fertilizers.Nevertheless,liquid fertilizers resulted in higher contents of nitrate and ammonium nitrogen than conventional fertilizers.The results demonstrate that liquid fertilizers can effectively replace conventional fertilizers and posi-tively influence inorganic nitrogen transformation in drip-irrigated cotton fields.关键词
