摘要: 【目的】本试验研究喷施浓缩沼液对棉花幼苗生长发育及生理特性的影响,为浓缩沼液水溶肥的合理施用提供理论依据。【方法】采用5种不同用量的浓缩沼液喷施盆栽棉花幼苗,研究不同喷施量(163 mL·hm-2、326 mL·hm-2,489 mL·hm-2、668 mL·hm-2、815 mL·hm-2)和喷施后时间(喷施后第2天、第4 天、第6 天)对棉花幼苗生长发育和生理指标的影响。【结果】结果表明:适宜喷施量的浓缩沼液对棉花生长发育有促进作用,过量的浓缩沼液则会抑制棉苗生长,喷施489 mL·hm-2浓缩沼液的株高、单株干物质质量、叶面积均最高,两批次试验喷施后第6 天的平均值分别比对照高21. 15%,35. 95%,18. 84%。喷施浓缩沼液还能提高棉花苗期叶绿素、可溶性糖、可溶性蛋白的含量,2个批次试验均以喷施489 mL·hm-2浓缩沼液的最高,平均值分别比对照高18. 84%,24. 03%,3. 16%。幼苗叶面喷施浓缩沼液后见效快,尤其以0~4 d内的效果最佳。【结论】适宜用量的浓缩沼液对棉花幼苗的生长发育和生理特性均有积极影响,利于棉花形成壮苗,为棉花后期生长打下良好基础。

Abstract: [Objective] The effect of concentrated biogas slurry on growth and physiological characteristics of cotton seedlings was studied in this experiment, and theoretical basis for the rational application of concentrated biogas slurry was provided. [Method] Potted cotton seedlings was sprayed by five different dosages of concentrated biogas slurry, the impact of different spraying quantity (163 mL·hm-2, 326 mL·hm-2, 489 mL·hm-2, 668 mL·hm-2, 815 mL·hm-2) after spraying time (after spraying 2nd day, 4th day, 6th day) on cotton seedlings growth and physiological indexes were studied. [Results] The results showed that the suitable quantity of spraying of concentrated biogas slurry had promoting effect to the cotton growth and development, the excess concentrated biogas slurry could inhibit the growth of cotton seedlings. The plant height, dry weight per plant and leaf area of spraying 489 mL·hm-2 processing are the highest, the average of two batches on the 6th day after spraying are 21.15%, 35.95%, 18.84% higher than CK, respectively. Spraying concentrated biogas slurry can improve cotton seedlings chlorophyll content, soluble sugar contents, soluble protein content. Spraying 489 mL·hm-2  processing is the highest in both batches, the average of two batches is 18.84%, 24.03%, 3.16% higher than CK, respectively. The result of concentrated biogas slurry on seedlings leaves took effect quickly, especially in 0~4th days. [Conclusion] It is concluded that the suitable amount of concentrated biogas slurry has a positive effect on the growth and physiological characteristics of cotton seedlings, which is beneficial to the formation of strong seedlings of cotton and provides the basis for the later growth of cotton.
