Effect of Application of Frequency of Amino-acid Foliar Fertilizer on Yield and Quality of Upper Tobacco Leaves
摘要
Abstract
Effect of application of frequency of amino -acid foliar fertilizer on yield and quality of upper tobacco leaves were studied in Longhui 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%and 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 .关键词
