几种中微量元素肥料对烤烟产量及品质的影响

2011年,在吉林省大安市、洮南市和镇赉县分别进行了大田烤烟,锰、硼、钼、锌和镁肥的施肥量和施用方法的试验研究。试验结果表明:在锰、硼、钼、锌和镁等中微量元素有效含量缺乏的烟田中,增施适量的中微肥,能够促进烤烟的营养均衡并在此基础上促进其生长;能够提高土壤和叶片中相应的中微量元素含量;烤烟的经济效益也随之得到提高。从试验长势看,所有试验中微肥都比对照好,喷施比基施表现要好,基施中硼、钼、锌、镁表现比较好,喷施中硼、钼、镁、钾+钼、钾+锌表现最好;从烘烤质量上看,不论基施的还是喷施的钼都表现得最好。

Effects of Several Kinds of Trace Element Fertilizers on Yield and Quality of Flue-cured Tobacco

In 2011,we studied the amount and method of tobacco fertilizer applied,including Mn,B,Mo,Zn and Mg,in Daan city,Zhenlai county and Taonan city.The results showed that the tobacco fields that lacked Mn,B,Mo,Zn,Mg and other trace elements,which is increased the amount of trace element fertilizer can improve tobacco’s nutritional balance and promote its growth;can increase the amount of relating trace elements in soil and leaves;the economic benefits of tobacco also can be enhanced.The specific result is:the growth of all treatments are better than CK,the spraying treatment is better than basal dressing,the better basal dressing treatment is B,Mo,Zn,Mg;the better spraying treatment is B,Mo,Mg,K+Mg,K+Zn.As for the baking quality of tobacco,the effect of Mo is the best both spraying and basal dressing treatment.
