施用不同形态肥料对烤烟生长发育及养分吸收的影响

Effects of Fertilizer Forms on Growth and Nutrient Uptake of Flue-cured Tobacco

摘要

摘要: 肥料的形态与土壤对养分的吸附固定和养分的有效性密切相关,为探明烤烟施用不同形态肥料的效果,采用盆栽试验研究了烤烟施用不同形态肥料的响应。结果表明,烟叶、烟茎、烟根干物质积累量均以施用颗粒肥处理为最大,分别比施用粉状BB肥的提高2.82%、2.88%和15.03%,比施用水溶液肥的提高2.08%、3.28%和11.93%;烤烟对氮磷钾养分的相对吸收量均以施用颗粒肥处理的最高(均以100%计),施用粉状BB肥的分别为96.6%、94.1%和90.4%,施用水溶液肥的分别为92.5%、96.3%和83.5%。试验得出,施用颗粒肥比粉状BB肥和水溶液肥更有利于烤烟干物质的积累和对氮磷钾养分的吸收利用,福建烤烟应提倡施用颗粒肥料。

Abstract: Fertilizer form could influence soil adsorption and fixation, thus the availability to tobacco plants.Pot experiments were conduced to study the effects of fertilizer forms on growth and nutrient uptake of flue-cured tobacco.The results showed that dry matter of leaves, stems and root of tobacco were the highest for granular fertilizer application, which were 2.82%, 2.88%, 15.03%, higher than those of powder fertilizer treatment, respectively, and 2.08%, 3.28%, 11.93% higher than those of solution fertilizer treatment.The relative uptake rates of flue-cured tobacco to N, P, K nutrients were 96.6%, 94.1%, 90.4% for powder fertilizer and 92.5%, 96.3%, 83.5% for solution fertilizer with regards to granular fertilizer.Application of granular fertilizer was more beneficial to the dry matter accumulation and NPK uptake for flue-cured tobacco than the rest two fertilizers.The granular fertilizer should be considered first for tobacco planting in Fujian.
