成熟期的烟田时常出现黑暴烟叶,影响采收和烘烤质量。1990年我们在凤城县通远堡镇曾家六组曾祥卜的黑暴烟田进行了乙烯利叶面喷施催熟的试验,取得很好效果。 去年8月下旬,曾祥卜的10亩烟田乙烤了7亩,而剩下的3亩黑暴烟基本不能烤。8月30日我们应用乙烯利对其烟叶催熟,用900倍液商品乙烯利喷洒。喷后33小时,将落黄7—10成的烟叶采收。上房时将10成黄的烟叶挂在烤房底棚,7—8成黄的挂在中间,进行烘烤。 由于乙烯利催熟的烟叶变黄比较快,含水量比正常成熟的烟叶高, Tobacco fields at maturity often appear black storm tobacco, harvesting and baking quality. In 1990, we conducted a test of ethephon spraying ripening in the black smoke field of Zengxiang Bu, Zengjiabu, Tongyuanpu Town, Fengcheng County, and achieved good results. In late August last year, Tsang Cheuk Bu’s 7 acres of tobacco fields B roasted 7 acres, while the remaining 3 acres of black smoke basically can not be baked. August 30 we use ethephon ripening their tobacco leaves, with 900 times the liquid ethephon spray. 33 hours after the spray, the fall of 7-10 into the tobacco leaves harvested. When the room will be 10 into yellow tobacco hanging in the barn shed, 7-8 yellow hanging in the middle for baking. As ethephon ripening leaves turn yellow faster, higher moisture content of the leaves than normal mature,
