| 摘 要： | 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。

| Abstract: | To identify the interaction between water and fertilizer on drip irrigation for cotton under plastic mulch, the field test is conducted in Awati County in Tarim river basin. The results show that the relationship between cotton yield and the irrigation norm or water consumption is linear in the conditions of irrigated water shortage and agricultural resources fail to bring effect. The coupling effects of water and fertilizer on drip irrigation for cotton under plastic mulch are significant. Water and fertilizer have the effect of increasing cotton yield, but when water and fertilizer supplies is excessive, the cotton yield will decrease. At last the proposal for improving the field test is presented. |
