摘　　要：[目的]探讨膜下滴灌条件下不同固体滴灌专用肥的施用效果。[方法]在新疆生态条件下,选用高产棉花品系293和710为试材,采用田间小区对比试验,分析不同滴灌专用肥对棉花生物学性状、干物质累积与分配及产量的影响。[结果]不同滴灌专用肥均能明显提高棉花产量;同时,滴灌专用肥可明显增强棉花的生物学性状,增加棉株总干物质累积量及生殖器官干物质累积量。不同品种对滴灌专用肥的响应不同,293对有机肥、生物肥反应敏感,710对有机肥、无机肥反应较敏感。[结论]依据不同品种对滴灌专用肥的响应,通过协调关键栽培技术调控棉花生长,进而调节棉株干物质累积与分配,对实现新疆棉花超高产、高效具有重要意义。[Objective]The effects of different solid drip-irrigation special-purpose fertilizer application were studied.[Method] A field experiment was conducted with different types and rates of fertilizer application and cultivars in Xinjiang.The effects of different solid drip-irrigation special-purpose fertilizer on biological characteristics,dry matter accumulation and partitioning and yield of cotton were studied.[Result] Drip-irrigation special-purpose fertilizer could increase the yield of the cotten compared with the control.Moreover,it could enhance the biological characteristics and increase the dry matter of plant and reproductive organs,respectively.Additional,different cultivars had different effects in response of drip-irrigation special-purpose fertilizer.The cultivar of 293 was sensitive to organic fertilizer and bio-fertilizer,and the cultivar of 710 was sensitive to organic and inorganic fertilizer.[Conclusion] According to the response of cotton cultivars to drip-irrigation special-purpose fertilizer,the accumulation and partitioning of dry matter should be regulated by using effective cultivation technique.It was meaningful for realizing the high production and high efficiency of cotton in Xinjiang.
