生物钾肥对烤烟 K326生长发育的影响OA北大核心CSCDCSTPCD
Effects of Biotic Potassium on Agronomic Characters and Economic Characters of Flue-cured Tobacco Variety K326
为了明确生物钾肥对烤烟生长的影响，在云南石林县对烤烟进行了施用常规肥料（CK ）与生物钾肥的比较试验，研究了生物钾肥对烤烟大田生育期、农艺性状、发病率、经济性状等的影响。结果表明：增施生物钾肥使烤烟还苗期缩短3d，整个大田生育期提前5d；增施生物钾肥烤烟的主根长为101cm，极显著高于CK （89 cm ）；在团棵期，增施生物钾肥的烤烟株高为31.5 cm ，显著高于CK （29.1 cm ），在旺长期和封顶后，增施生物钾肥烤烟的农艺性状与CK差…查看全部>>
In order to study the effects of biotic potassium on the grow th of flue-cured tobacco ,the comparative tests were conducted between conventional fertilizer and biotic potassium in Shilin country .The effects of biotic potassium on growth period ,agronomic characters ,disease incidence and economic characters of the flue-cured tobacco were studied .The results showed that the see-ding stage was shortened by three days through applying biotic potassium ,and t…查看全部>>
