改型顆粒鉀肥對(duì)烤煙煙葉含鉀量及品質(zhì)的影響
Effects of modified potassium fertilizer on potassium content and quality of tobacco leaves
-
摘要: 室內(nèi)實(shí)驗(yàn)證明, 添加吸附材料可使改型鉀肥釋放鉀離子的速度明顯慢于普通三元復(fù)合肥。盆栽和田間試驗(yàn)結(jié)果顯示, 硫酸鉀經(jīng)過(guò)添加吸附材料改型后施用, 可提高煙葉鉀含量; 2002 年下部葉鉀含量增加0.52 個(gè)百分點(diǎn), 2003年中部葉鉀含量增加0.2 個(gè)百分點(diǎn),。施用改型鉀肥能改善香氣質(zhì)、提高香氣量, 突出表現(xiàn)為煙葉余味更加舒適, 刺激性減輕,。Abstract: The test results showed that with absorbent added into potassium fertilizer, the releasing velocity of potassium ions was slower than ordinary fertilizer. The results of the pot experiments and field tests were showed that with absorbent added in, the potassium content of tobacco leaves increased, potassium concentration of lower leaves was raised by 0.5 percent in 2002; potassium concentration of central leaves was raised by 0.2 percent in 2003. In addition, the modified fertilizer could improve quality of tobacco aroma, increase quantity oftobacco aroma, amend tobacco aftertaste and alleviate tobacco thrill.
