气候和土壤肥力对积水棉田叶面供氮效果的影响澳大利亚多数灌溉锦田排水不畅，沟灌后随之发生短期棉田积水，导致棉花减产。原因之之一是棉花对氮素的吸收减少。在灌溉前实施叶面喷氮可以克服这种瞬时的供氮不足。在澳大利亚新南威尔士州的纳拉布赖，生长季气候和土壤氮素... Impact of climate and soil fertility on foliar nitrogen availability in plotted cotton fields. Most of the irrigation in Australia is poorly drained, resulting in short-term waterlogging in the cotton fields following furrow irrigation, resulting in a reduction in cotton production. One of the reasons is that cotton has less absorption of nitrogen. Applying foliar nitrogen before irrigating can overcome this transient shortage of nitrogen supply.
