速效烟草肥是四川省农科院农科技术部近年来研制的专用于烟草的生长剂。烟草施用后效果十分显著,且用量少、见效快、使用方便,水剂每亩100毫升,在烟草生长期仅使用一次,于收获前25～20天叶面喷施追肥,数天即显效。速效烟草肥的功效是多方面综合性的,主要表现在提高产量、防治病害、提高品质三个方面。且显效迅速。经数年试用后,1989年在四川省烟草主产区什邡县进行了应用示范。品种为二季晒烟,于收获前25天(1989年5月27日下午2时30分,晴,气温27℃)用速效烟草肥叶面喷施。据观察:喷后叶色迅速转青嫩,叶片发亮,手感柔和细腻,油润,叶片比同田对照增宽增长,茸毛增多(见表1)。
Quick-acting tobacco is the Sichuan Academy of Agricultural Sciences Department of Agricultural Technology in recent years developed specifically for tobacco growth agent. After the application of tobacco is very significant, and the amount of less effective, easy to use, 100 ml per acre agent, only used once in the tobacco growing season, 25 to 20 days before harvest foliar application topdressing, effective for several days . The effectiveness of quick-acting tobacco fertilizer is comprehensive and comprehensive in many aspects, mainly in three aspects: increasing yield, preventing diseases and improving quality. And markedly rapid. After several years of trial, in 1989 in Shichuan County, Sichuan Province, the main tobacco production demonstration. Varieties for the second season sunburn, 25 days before harvest (at 27:30 on May 27, 1989, sunny, temperature 27 ℃) with quick-acting tobacco fertilizer foliar spray. It is observed: after spraying the leaf color quickly turn young and tender, leaf shiny, soft and delicate hand, oil, leaves than the same field control broaden growth, increased hair (see Table 1).
