Abstract

Purpose Improving physio-chemical properties under irrigation regime by using natural conditioners to achieve the highest possible crop yield and water productivity. Method  A field experiment was conducted in a split-plot design with three replicates by addition of canal clay scouring (CS) and compost (CO) during two consecutive growing winter seasons of 2018/19 and 2019/20. The treatments were: control (100% and75% of water requirements), 20 and 40 (ton. ha-1) of CO and 40 and 80 (ton. ha-1) of CS as alone or mixed with each other under drip irrigation. Results The results showed that soil organic matter and cation exchange capacity increased by increasing the application rates of CO and CS. The lowest values of bulk and hydraulic conductivity were observed at 80 ton. ha-1 CS +40 ton. ha-1 CO. Also, field capacity, wilting point and available water were 20.94,5.97 and5.07%, respectively. The lowest values of ETa were observed at 80 ton. ha-1 CS +40 ton. ha-1 CO under 75% water irrigation requirement in all growth stages. The highest rates of the studied materials as a mixture gave a significant increase in nitrogen, phosphorus and potassium contents of grains and straw of wheat crop. The highest yield of straw and grain were 9523.81 and 6428.57 kg ha-1, respectively. Also, it could be observed that the highest percentage of CWP and IWP were 21.05 and 14.53%, respectively, under 75% irrigation water requirement. Conclusion Application of clay and compost can improve soil physio-chemical properties, water productivity and crop yield under irrigation water regime.
灌溉水条件下堆肥和渠道粘土冲刷对沙土性质和小麦产量的影响
目的利用自然调理剂改善灌溉条件下作物的理化性状,使作物产量和水分生产力达到最高水平。方法采用3个重复的田间试验设计,在2018/19和2019/20两个连续生长冬季分别添加沟渠粘土冲刷(CS)和堆肥(CO)。处理分别为:对照(需水量100%和75%)、20和40(吨)。ha-1), 40和80(吨)。在滴灌条件下,CS单独或混合的ha-1)。结果随着CO和CS施用量的增加,土壤有机质和阳离子交换量均有所增加。体积和水力导电性在80吨时达到最低值。ha-1 CS +40吨。田间容量、凋萎点和有效水分分别为20.94%、5.97%和5.07%。ETa在80吨时达到最低值。ha-1 CS +40吨。各生育期需水量75%下ha-1 CO。混合处理对小麦籽粒和秸秆氮、磷、钾含量均有显著提高。秸秆和籽粒最高产量分别为9523.81 kg hm -1和6428.57 kg hm -1。当灌溉需水量为75%时,CWP和IWP最高,分别为21.5%和14.53%。结论在灌溉水条件下,施用粘土和堆肥可改善土壤理化性质,提高水分生产力和作物产量。
