摘要
[目的]研究锌肥的施用量对烤烟红花大金元大田生育期内生长发育的影响,改善烟叶大田生长管理措施,进一步提高烟叶质量增加烟农收入.[方法]对红花大金元施用不同量的硫酸锌,并对大田生育期内的烤烟农艺性状、干物质积累量、硝酸还原酶的活性以及可溶性糖的含量进行测定.[结果]随着硫酸锌施用量增加,红花大金元的各农艺性状有着不同的变化趋势,但总体呈现先增后减的趋势.且在使用量为200 mg/株时表现最好;烤烟干物质的积累中根系干物质的积累在T1与T2处理表现较好,茎秆的干物质积累以施用300 mg/株时表现最好,叶片的干物质积累在T2处理较好;施用硫酸锌能提高硝酸还原酶的活性,且施用量为300 mg/株时显著高于对照;45～75 d时施用硫酸锌的各处理中,可溶性蛋白含量均高于或者显著高于对照.[结论]在一定范围内,硫酸锌施用量的增加有利于提高烟叶中的农艺性状、干物质积累、硝酸还原酶活性以及可溶性蛋白含量.
Abstract
[Objective] To study the effects of zinc fertilizer application amount on the growth and development of flue-cured tobacco Honghuadajinyuan,to improve the growth management measures in tobacco field,and to further enhance the tobacco leaf quality and the income of tobacco farmers.[Method] Different amounts of zinc sulfate were applied.And the agronomic characters,dry matter accumulation,nitrate reductase activity and soluble sugar content of Honghuadajinyuan were detected.[Result] With the increase of the amount of zinc sulfate,agronomic traits of Honghuadajinyuan had different change trends,but showed the tendency of first increase and then decrease in general.The best performance appeared at the dosage of 200 mg/plant;dry matter accumulation in flue-cured tobacco root showed better performance in treatments T1 and T2.Dry matter accumulation in stem showed the best performance at the dosage of 300 mg/plant,dry matter accumulation in leaves was better in treatment T2.Application of zinc sulfate enhanced the activity of nitrate reductase,and 300 mg/plant fertilizer had significantly higher activity than the control.Soluble protein contents in zinc sulfate treatments were higher or significantly higher than that of control at 45-75 d.[Conclusion] Within a certain range,increase of zinc sulfate amount is helpful to the enhancement of agronomic characters,dry matter accumulation,nitrate reductase activity and soluble sugar content of tobacco leaves.
