摘  要：
【目的】研究复硝酚钠(CSN)与胺鲜酯(DA-6) 2种植物生长调节剂,分别和化肥复配施用对棉花化肥吸收率的影响。【方法】通过复硝酚硝与胺鲜酯分别和化肥复配施用,采集棉花2叶期、4叶期、6叶期各20株,测定棉株鲜重,干重,以及全氮、全磷和全钾含量,计算棉花3个时期的干物质比、氮吸收率、磷吸收率、钾吸收率,与CK相比较,分析复硝酚钠与胺鲜酯对棉花肥料吸收率的影响。【结果】复硝酚钠和化肥复配施肥后,棉花对肥料的吸收率在2叶期时氮、磷、钾吸收率分别提高了10. 76%、0. 87%和10. 4%。4叶期时氮、磷、钾吸收率分别提高了18. 5%、2. 34%和24. 86%。6叶期时氮、磷、钾吸收率分别提高了31. 14%、5. 33%和35. 56%;胺鲜酯和化肥复配施肥后棉花对肥料的吸收率在2叶期时氮、磷、钾吸收率分别提高了8. 31%、0. 85%和9. 25%。4叶期时氮、磷、钾吸收率分别提高了11. 51%、1. 48%和15. 66%。6叶期时氮、磷、钾吸收率分别提高了27. 11%、4. 49%和30. 31%。【结论】复硝酚钠与胺鲜酯与化肥复配施用,对棉花化肥吸收率有明显的促进作用。

摘  要：
【Objective】The purpose of this study aims to explore the effect of compound sodium nitrophenolate(CSN) and DA-6 on the chemical fertilizer absorption rate of cotton.【Method】Through 20 cotton plants collected at 2-leaf stage,4-leaf stage and 6-leaf stage by compound application of compound sodium nitrophenolate,DA-6 and chemical fertilizer,the fresh weight,dry weight,total nitrogen content,total phosphorus content and total potassium content of cotton plants were determined,and the dry matter ratio,nitrogen absorption rate,phosphorus absorption rate and potassium absorption rate of cotton in three stages were calculated and compared with CK.In addition,the effects of compound sodium nitrophenolate and DA-6 on the chemical fertilizer absorption rate of cotton were studied.【Result】After the compound fertilization of compound sodium nitrophenolate and chemical fertilizer,the absorption rate of N,P and K increased by 10.76%,0.87% and10.4% respectively in the the 2-leaf stage,the absorption rates of N,P and K increased by 18.5%,2.34%and 24.86% respectively in the 4-leaf stage and the absorption rates of N,P and K increased by 31.14%,5.33% and 35.56% respectively in the 6-leaf stage; After the compound fertilization of DA-6 and chemical fertilizer,the absorption rates of N,P and K increased by 8.31%,0.85% and 9.25% respectively in the 2-leaf stage,the absorption rates of N,P and K increased by 11.51%,1.48% and 15.66% respectively in the 4-leaf stage and the absorption rates of N,P and K increased by 27.11%,4.49% and 30.31% respectively in the 6-leaf stage.【Conclusion】The compound application of compound sodium nitrophenolate,DA-6 and chemical fertilizer can obviously promote the chemical fertilizer absorption rate of cotton.
