摘要
为促进新疆小流量高频次智能滴灌技术的应用与推广,确定棉花滴灌带适宜的滴头流量范围和灌水量,于2022-2024年在新疆昌吉棉花地滴灌系统基础上配套应用智能计量与管控装备,开展灌溉试验研究。将棉花田分等面积4块试验区,在相同的首部条件、灌溉水源、施肥量、农艺管理和统一智能管控条件下,选用滴头流量分别为0.8、1.4、1.8和2.2 L/h等4种滴灌带,监测与分析各试验区灌水量、灌水次数、灌水均匀度与产量等指标。研究结果表明:滴灌系统配套使用智能管控装备情况下,采用以上4种不同滴头的小流量滴灌带进行灌溉时,灌水量平均为195.0、225.0、270.0和330.0 m^(3)/hm^(2),灌溉定额分别为3 985.5、3 955.5、3 955.5和4 015.5 m^(3)/hm^(2),灌水均匀度为93.27%、92.86%、92.55%和90.08%,产量分别为6 645、7 455、7 380和7 155 kg/hm^(2)。经综合分析,建议昌吉州智能滴灌棉花栽培管理的最佳滴灌带滴头流量为1.4 L/h,对应灌水频次为17次、灌水周期为4 d。
To establish the application and promotion of low flowrate and high frequency smart drip irrigation technology for cotton,and to determine the appropriate discharge rate of emitter and irrigation quota,experimental studies were carried out in Changji,Xinjiang between 2022 and 2024.An experimental field was divided into four equal plots.All plots shared the same headworks,water source,fertilization rates,and agronomic management under a unified intelligent control system.Four types of drip tapes with different emitter flow rates(0.8、1.4、1.8 and 2.2 L/h)were used.Key indicators,including irrigation amount,frequency,uniformity,and yield,were monitored and analyzed for each plot.The results show that,the average irrigation quota are 195.0、225.0、270.0 and 330.0 m^(3)/hm^(2),irrigation quotas are 3985.5、3955.5、3955.5 and 4015.5 m^(3)/hm^(2),irrigation uniformities are 93.27%、92.86%、92.55%and 90.08%,yields are 6645、7455、7380 and 7155 kg/hm^(2).Through comprehensive analysis,it is recommended that the optimal discharge rate of emitter with smart drip irrigation of cotton is 1.4 L/h,corresponding irrigation frequency is 17 times and irrigation cycle is 4 days.
