对膜下滴灌棉花的水肥耦合效应进行了田间试验。结果表明 :在灌水量不足、农业资源未能充分发挥条件下 ,棉花产量与灌水量及耗水量呈线性关系 ;膜下滴灌棉花的水肥耦合效应明显 ,水肥都具有增产效果 ,但过多的水肥投入并不有利于棉花增产。最后对进一步完善膜下滴灌棉花水肥耦合试验提出了建议。
A field experiment was conducted on the water-fertilizer coupling effect of cotton under drip irrigation. The results showed that there was a linear relationship between cotton yield and irrigation amount and water consumption under the condition of insufficient irrigation and inadequate utilization of agricultural resources. The coupling effects of water and fertilizer on cotton under drip irrigation were obvious, Input is not conducive to cotton production. Finally, some suggestions are put forward to further improve the coupling experiment of drip irrigation under water and fertilizer.
