采用盆栽试验方法,研究了不同组分的腐植酸复合肥对辣椒生长及其生理特性的影响,以筛选出适于辣椒生长的最佳肥料方案。试验结果表明,不同组分腐植酸复合肥处理与等养分无机复合肥及对照相比,产量均有显著提高,提高幅度分别为8.1％～23.5％和165.0％～195.1％。其中以HAzn增产效果最为显著。对辣椒生理活性的影响,也是以HAZn总体表现效果最佳,它可提高辣椒体内NR、SOD、POD的活性,促进叶绿素的合成代谢。此外,微量元素锌、铁之间存在着一定的拮抗作用,在一个施肥方案中,二者不宜同时施用。
Pot experiments were conducted to study the effects of different components of humic acid compound fertilizer on the growth and physiological characteristics of pepper in order to select the best fertilizer plan suitable for the growth of pepper. The results showed that the yield of humic acid compound fertilizer with different components was significantly increased from 8.1% to 23.5% and 165.0% to 195.1% compared with that of the same nutrient compound fertilizer and control. Which HAzn yield the most significant effect. The physiological activity of pepper, HAZn is also the overall performance of the best, it can increase pepper body NR, SOD, POD activity, and promote the synthesis of chlorophyll metabolism. In addition, trace elements zinc, iron there is a certain antagonism, in a fertilization program, the two should not be applied at the same time.
