The test of the new type of leaf fertilization is a composite of foliar fertilization. Study on the new type of foliar fertilization and JinBiSheng foliar fertilization, and on the different of the spraying times, the spraying period, the spraying concentration of new type of foliar fertilization, to establish new foliar fertilization in DaoXian flue-cured tobacco production in the specific effect and some related technologies, for the DaoXian in the popularization and application of the lay the foundation.1,New type of leaf fertilizer and JinBiSheng leaf fertilizer can promote flue-cured tobacco open the upper leaves and layered fall yellow, improve the quality and production level, with the identity, structure, and color of the upper leaves after curing get a different appearance quality of improved. The effect of new type of leaf fertilizer is better than JinBiSheng leaf fertilizer.2,The effect in spraying 2-3 times foliar fertilizer after topping t is better than spraying 1 time, spraying three times foliar fertilizer than spraying two times in improving the fine rate and improve tobacco smoke chemical composition of the coordination to a certain extent and advantages, but the distinction between is not big. Taken together, spraying two times foliar fertilization after topping is able to achieve better effect in reducing the labor.3,The result in different period of the tobacco leaf spraying the new foliar fertilization is:The effect spraying foliar fertilization in time after topping is in the most significant. The effect of spraying premise seven days before topping and delay spraying after topping are all declined than spraying topping, and the effect of spraying delayed seven days after topping is more obvious.4,Dilution of the new type of foliar fertilization 200 times original treatment can obviously improve the rate than the contrast medium smoke; Stock dilute 150 times treatment can increase production, medium smoke rate; Diluted 100 times in original deal with superior smoke rate increase was not significant outside, other economic characters are significantly increased than the control; Stock dilute 50 times as the treatment effect is not obvious. Comprehensive economic characters come to see, dilute flue-cured tobacco original 150 times the processing effects better.
