【摘要】 应用富万钾、泰叶得、绿帝3号、磷酸二氢钾等四种烟草型叶面肥,在烤烟品种MSK326的苗期和大田生长期进行喷施处理,结果表明:与对照比,苗期喷施叶面肥处理,能明显促进烟苗的稳生壮长、增强烟苗抗病力,提高烟苗的素质;在大田生长期喷施叶面肥处理,能促进烤烟大田植株生长健壮,提高植株的抗病性;各处理的烟叶产量、产值、均价、上中等烟率均高于对照,烟叶外观质量明显改善,其中喷施富万钾的产量在所有处理中最高,平均每公顷产量为2751.3kg,比对照增产36.6%;每公顷产值为19974.44元,比对照增加产值53.3%,产投比达到1:23.15,经济效益显著。更多还原

【Abstract】 Sprayed on the leaves during seedling stage and field growth period,the Flue-cured Tobacco MSK326 was treated with four kinds of Leaf-absorbed fertilizers: Fuwanjia,Tuyuede,Nudi.NO.3 and KH2PO4.The results showed that these fertilizers can promote the seedling growth,higher disease resistance and quality of tobacco.Seedlings treated with these fertilizers during seedling stage all represented better features than those of the control group.During field growth period,the fertilizers can promote growth and higher disease resistance,the yields and average prices and A&B grade ratio of tobacco leaves treated with these leaf fertilizers all were higher than the control group.The physical quality of tobacco was obviously improved.The treatment with Fuwanjia had highest yields among the fertilizers with a yield increase of 2751.3 kg/ha.,which was significantly higher than the control group by 36.6%,the production value was 19974.44 Yuan/ha.,which was significantly higher than the control group by 53.3%,the ratio of input-output was 1:23.15 with an obvious economic benefit.更多还原
