有机·无机肥不同比例配施对灵宝烤烟物理特性的影响

Impact of Organic,Inorganic Fertilizer with Different Proportion on Physical Characteristics of Flue-cured Tobacco in Lingbao City

为明确有机、无机肥不同比例配施对灵宝市烤烟物理特性的影响,设置5个处理(T1为0%有机肥+100%无机肥;T2为25%有机肥+75%无机肥;T3为50%有机肥+50%无机肥;T4为75%有机肥+25%无机肥;T5为100%有机肥+0%无机肥),以探寻最佳比例,指导烤烟大田生产。结果表明,肥料配比中适当增加有机肥,可以促进叶片发育。有机肥的添加可以提高烟叶的填充值、中下部叶片的抗张力、单叶重,但100%有机肥处理反而会降低上部叶和下部叶的填充值、抗张力、单叶重,降低可用性。T2处理能够增加下部叶的厚度,增加上中部叶片的单叶重。

In order to make clear the impact of organic,inorganic fertilizer with different proportion on physical characteristics of flue-cured tobacco in Lingbao City,five treatments were set(T1:0%organic fertilizer+100%inorganic fertilizer;T2:25%+75%;T:350%+50%;T4:75%+25%;T5:100%+0%),to explore the best proportion and give guidance to flue-cured tobacco production.The result showed that increasing proportion of organic fertilizer could promote leaf development.Organic fertilizer could improve tobacco leaf filling value,tension,leaf weight,but the 100%organic fertilizer would reduce the filling value tension,leaf weight of upper leaves and lower leaves.T2 could increase thickness of the lower leaf,and leaf weight of the middle leaves.
