1. Do not use during flowering period
Crops should not be sprayed with foliar fertilizer in the flowering period, which is the stage of pollination and fruiting. Fertilization in this period is easy to burn flowers, which is not conducive to normal pollination and thus reduces the yield.
2. Do not use it at high temperature in the afternoon
Foliar fertilizer is a kind of efficient nutrient liquid composition. If foliar fertilizer is sprayed in hot weather, it will cause nutrient evaporation, and nutrient concentration will be reduced in rainy season, both of which significantly reduce the utilization rate of foliar fertilizer.
3. It is forbidden to use the seedlings when they are not slowed down
In the seedling stage, most of the crops have just started to germinate, or cannot be sprayed with foliar fertilizer after transplanting, because at this time, the crops themselves are not only fragile, not so adapt to the external conditions, generally sprayed with nutrient solution, it is easy to cause the phenomenon of burning seedlings and burning leaves, not conducive to the normal growth of seedlings.
