摘要
【目的】研究不同棉花品种在新疆塔里木棉区的养分积累量及产量特性。【方法】设置3种基肥用量,采用两因素裂区试验设计,比较6个棉花品种在3种基肥设置下养分积累差异及产量影响。【结果】6个棉花品种中新陆中55号品种的氮素利用率最高(36.11%),具有较高的氮素吸收能力。新陆中22号、新陆中55号、锦棉Z1112品种的磷积累量显著高于新陆中82号、新陆早74号、新陆早77号品种,磷肥利用效率表现为新陆早77号>新陆中22号>新陆中82号>新陆中55号>锦棉Z1112>新陆早74号。新陆中22号、新陆中55号、新陆中82号、锦棉Z1112、新陆早77号品种的钾含量显著高于新陆早74号品种,钾肥利用效率表现为新陆中55号和新陆中82号较高,新陆中22号品种最低,新陆中55号和新陆中82号品种具有较高的钾素吸收能力;锦棉Z1112、新陆早77号品种的单株铃数显著高于新陆中22号、新陆中55号品种,新陆中22号品种的单铃重显著高于其他5个品种。新陆中22号、锦棉Z1112品种的衣分要显著高于新陆中55号、新陆中82号、新陆早77号品种,新陆早74号品种籽棉产量和皮棉产量均显著低于其他品种。【结论】不施基肥处理棉花株养分吸收积累量少、产量偏低。基肥全施处理下产量最高,基肥半施处理下,基肥施用量减少50%,棉花平均产量减少9%,其中新陆中22号品种和新陆中55号品种的减产最少,为5%和1%。
【Objective】In this study,three kinds of base fertilizers were set up to compare the nutrient accumulation and yield characteristics of different cotton varieties in the Tarim area of Xinjiang.【Methods】Two-factor split-zone test design was adopted to compare the nutrient accumulation differences and yield effects of six cotton varieties under three basic fertilizer settings.【Results】The results showed that the Xinluzhong55 varietyof the six cotton cultivars had the highest nitrogen utilization rate(36.11%)with high nitrogen uptake capacity.The phosphorus accumulations of Xinluzhong22,Xinluzhong55 and JinmianZ1112 varieties were significantly higher than thoseof Xinluzhong82,Xinluzao74 and Xinluzao77 varieties.The utilization efficiency of phosphate fertilizer was Xinluzao77>Xinluzhong22>Xinluzhong82>Xinluzhong55>JinmianZ1112>Xinluzao74.The potassium contents of Xinluzhong22,Xinluzhong55,Xinluzhong82,JinmianZ1112 and Xinluzao77 varieties weresignificantly higher than that of Xinluzao74 varieties.The utilization efficiency of potassium fertilizer was higher than thoseof Xinluzhong55 and Xinluzhong82,the lowest one was Xinluzhong22 variety,and Xinluzhong55 and Xinluzhong82 varieties had higher potassium absorption capacity;The numbers of bolls per plant of JinmianZ1112 and Xinluzao776 weresignificantly higher than thoseof Xinluzhong22 and Xinluzhong55,and the single boll weight of Xinluzhong22 was significantly higher than that of the other five varieties.The clothing scores of Xinluzhong22 and JinmianZ1112 varieties were significantly higher than those of Xinluzhong55,Xinluzhong82 and Xinluzao77 varieties.The seed cotton yield and lint yield of Xinluzao74 varietywere significantly lower than those other varieties.【Conclusion】Under the current planting conditions,the nutrient absorption and accumulation of cotton plants without the application of base fertilizer was low and the yield was low.Under the total application of base fertilizer,the yield was the highest.Under the semi-application of base fertilizer,the application rate of base fertilizer was reduced by 50%,and the average yield of cotton was reduced by 9%.Among them,Xinluzhong22 and Xinluzhong55 varieties had the least yield reduction,5%and 1%,respectively.
