钼营养对烤烟干物质积累、钼素分配和利用率的影响
Effects of Molybdenum on the Accumulation of Dry Matter,Distribution and Utilization of Molybdenum of Flue-cured Tobacco
摘要
Abstract
The effects of molybdenum nutrition of different dosages on the accumulation of dry matter, distribution and utilization of molybdenum in different organs of flue-cured tobacco were studied by Pot and field experiments.The pot experiment used 4 Mo dose levels and CK (water), and the field experiment was carried out in the main producing area in Qiannan ,in which 9 plotes were used for the the experiment with a was layed out unified scheme. The molybdenum contents in different reproductive stages were determined with KCNS colorimetric method and analysed with SPSS.(1)With the prolongation of growing period, the dry matter accumulation increased, and there were different changing rules in molybdenum contents.(2) All the tobacco plants applied with different levels of molybdenum had the highest Mo content in leaves, and was higher than that in CK. (3)With the increase of molybdenum levels, the accumulation of molybdenum increasedAs for molybdenum level changes, Each of the treatment,had difference by tobacco plant uptake of Mo element efficiency.The accumulation of dry matter was promoted and the distribution ratio of molybdenum in tobacco plant was regulated by molybdenum nutrient. To a certain extent, the content of molybdenum and the distribution ratio in the leaves were increased.关键词
