叶肥是一种含氮、磷、钾、镁、锌、铜、硼、锰、钼等多种元素的复合肥料。主要用于作物叶面喷施,具有用量小、肥效快的优点,而且可防止肥料渗漏,减少磷酸固定,是一种新型高效复合肥料。为探讨叶肥对培育烤烟壮苗和提高烟叶品质的作用,从1985年起,进行了烤烟喷施叶肥的试验。1986年又在28.94亩移栽用的烟苗和15.45亩烟田上做了喷施叶肥的示范。试验和示范表明,喷施叶肥对培育烤烟壮苗,提高烟叶
Leaf fertilizer is a nitrogen, phosphorus, potassium, magnesium, zinc, copper, boron, manganese, molybdenum and other elements of the compound fertilizer. Mainly used for crop foliar spray, with the advantages of small dosage, fast efficiency, but also to prevent fertilizer leakage, reduce phosphate fixation, is a new type of high efficiency compound fertilizer. In order to investigate the effect of leaf fertilizer on fostering strong seedlings and improving the quality of flue-cured tobacco, the experiment of spraying leaf fertilizer on flue-cured tobacco was carried out since 1985. In 1986, 28.94 mu of transplanting tobacco seedlings and 15.45 mu of tobacco fields were sprayed with leaf fertilizer. Tests and demonstrations show that spraying leaf fertilizer on nurturing flue-cured tobacco seedlings to improve tobacco
