摘要
为研究土壤类型对烤烟生长和品质的影响,以延边烟区黑土、粘土和沙壤土为材料,研究了3种土壤上种植的烤烟各时期生长率和烤后烟叶的理化特性。结果表明,各类型烟田土壤pH值、有机质和碱解氮差异不大,其中,粘土的碱解氮含量变化幅度明显大于黑土和沙壤土,可见氮对烟草生长发育起着重要作用。在生育前期,沙壤土上移栽的烟苗前期生长良好,植株高大,但是到了生育后期,鲜干重明显下降。可见,沙壤土不利于保水保肥和烟株的生长。
In order to study the effects of soil types on the growth and quality of flue-cured tobacco,the growth rate of three kinds of flue-cured tobacco and the physical and chemical properties of flue-cured tobacco were studied.The results showed that the soil pH value and organic matter and alkali solution nitrogen were different in different types of tobacco field,and the change range of soil alkaline nitrogen content was significantly higher than that in black soil and sandy loam soil.In the early stage of growth,the growth of the seedlings of the sand loam soil was good,but the fresh dry weight decreased significantly in the late stage of the growth.The results showed that the loam is not conducive to the growth of water and fertilizer and tobacco plants.
