[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 research aimed to discuss the application effect of drip irrigation with special solid fertilizers under drip irrigation. [Method] Under the ecological conditions of Xinjiang, 293 and 710 with high - yielding cotton lines were selected as experimental materials. The effects of different drip irrigation special fertilizers on cotton biological characteristics, dry matter accumulation and distribution and yield were analyzed by field plot comparative experiments. [Result] Different drip irrigation special fertilizers could obviously increase the cotton yield. At the same time, drip irrigation special fertilizer could obviously enhance the biological characters of cotton and increase the total dry matter accumulation of cotton plant and the accumulation of dry matter of reproductive organs. Different varieties of drip irrigation specific response, 293 pairs of organic fertilizer, biological fertilizer sensitive, 710 pairs of organic fertilizer, inorganic fertilizer more sensitive. [Conclusion] According to the response of different varieties to drip irrigation special fertilizer, coordinating the key cultivation techniques to regulate the cotton growth and then regulating the accumulation and distribution of dry matter in cotton plants was very important to realize the super high yield and high efficiency of Xinjiang cotton.
