摘要
为探究新型复合保水剂对半干旱地区烤烟生产的影响,通过田间试验,以不施保水剂为对照,研究传统保水剂(聚丙烯酸盐保水剂、聚乙烯醇-丙烯酸保水剂)和新型复合保水剂(生物炭复合保水剂、腐殖酸钾复合保水剂)对烤烟生长状况、碳氮代谢关键酶活性、有机酸和常规化学成分的影响。结果表明,生物炭复合保水剂和腐殖酸钾复合保水剂相较于传统保水剂更有利于提高烟叶最大叶长和烟株根系体积,促进烤烟碳氮代谢能力,提高烟叶淀粉酶(AL)、中性转化酶(NI)和硝酸还原酶(NR)活性;生物炭复合保水剂和腐殖酸钾复合保水剂显著提高烟叶非挥发性有机酸总量,其中腐殖酸钾复合保水剂增幅较大,苹果酸、柠檬酸含量较对照分别提高16.8%、29.8%和30.5%、27.9%,同时还提高了烟叶总糖、还原糖、烟碱、钾、氯含量以及糖碱比。施用新型复合保水剂更有利于促进半干旱地区烤烟生产。
To investigate the effects of new composite water retention agents on the production of flue-cured tobacco in semi-arid areas,we investigated the effects of classical water retention agents(polyacrylate water retention agent and polyvinyl alcohol-acrylic acid water retention agent)and new composite water retention agents(biochar composite water retention agent and potassium humate composite water retention agent)on growth,activities of key enzyme in carbon,nitrogen metabolism,organic acids and conventional chemical composition of flue-cured tobacco through field trials,with no water retention agent as control.The results showed that biochar composite water retention agent and potassium humate composite water retention agent were more effective than the classical water retention agents in increasing the maximum leaf length and root volume,promoting carbon and nitrogen metabolism of tobacco leaves,and increasing the activities of amylase(AL),neutral transforming enzyme(NI)and nitrate reductase(NR)in tobacco leaves.The biochar composite water retention agent and potassium humate composite water retention agent could significantly increase the total non-volatile organic acids in tobacco leaves.The potassium humate compound water retention agent was more effective,increasing malic acid and citric acid contents by 16.8%,29.8%and 30.5%,27.9%,respectively,compared with the control.The treatments also increased the contents of total sugar,reducing sugar,nicotine,potassium and chloride and sugar to alkali ratio in tobacco leaves.Application of new composite water retention agents can be beneficial in promoting flue-cured tobacco production in semi-arid areas.
