| 摘 要： | 通过大田试验,比较研究常规栽培(T1)、一次性分层施肥栽培(T2)、一次性施肥的平地覆膜栽培(T3)三种栽培模式对植烟土壤物理性状、烤烟生长及产量等的影响.试验结果表明:T2和T3栽培提高了耕层的土壤含水量和土壤温度,显著提高烤烟植株中部叶的全氮、全磷含量,显著提高了烤烟植株上、中、下部叶的全钾含量;T3栽培极显著提高...

| Abstract: | By means of field comparison expeirment,conventional cultivation(T1),once delamination fertilization(T2) and once ground film-covered(T3) were researched to find their impact on soil physical characters,tobacco growth and yield etc.The experiment results show that T2 and T3 cultivations can increase soil water content and temperature,obviously increase the Total N and P contents in tobacco leaves at middle position of a plant,increase total K content in tobacco leaves at upper,middle and lower positions of a plant.T3 cultivation canextra obviously increase the proportion of first grade tobacco,meanwhile,T2 and T3’s impacts on yield,mean price and produ tion value of tobacco leaves are not obvious.T2 and T3 cultivations can save labor cost so that they are worth to be extended at prodution. |
