摘 要:2011年在湖南隆回开展了喷施氨基酸叶面肥对烤烟上部叶产质量影响的研究,结果表明:在减少基肥和硝酸钾用量的基础上,与不喷施的对照相比较,喷施氨基酸叶面肥均有利于促进上部叶开片,喷施1和2次可以增大上部烟叶面积10.3%-14.6%和3.1%~18.9%,并且明显改善烟叶的外观质量和内在品质,提高中上等烟叶比例0.2%和0.8%,增加产值分别达1246形hm2和4096元/hm2,从而有利于提高上部烟叶的工业町用性,提高植烟的经济效益。Effect of application of frequency of amino - acid foliar fertilizer on yield and quality of upper tobacco leaves were studied in l_onghui county in 2011. The results showed that on the basis of reducing application rate of basal fertilizer and potassium nitrate, compared to CK, spraying amino - acid foliar fertilizer was advantageous to expanding of upper leaves, spraying once and twice could increase the area of upper leaves 10. 3% - 14. 6% and 3.1% - 18. 9% respectively, obvious- ly improve the appearance and internal quality of upper leaves, increase the proportion of mid - high grade leaves 0. 2% anti 0. 8% respectively, and increase the output value 1246 yuan/hm2 and 4096 yuan/hm2 respectively. So spraying amino -acid foliar fertilizer was advantageous to improve the industry usability of upper leaves and economic benefit.
