1）Prohibited during flowering period
Crops should not be sprayed with foliar fertilizer during the flowering period, which is the stage of pollination and fruiting. Fertilization during this period can easily burn flowers, which is not conducive to normal pollination and thus reduce yield.
The effect of foliar fertilization is directly related to temperature, humidity, and wind power. For foliar spraying, it is best to choose a windless and cloudy day or a day with high humidity and low evaporation before 9:00 a.m. The most suitable time is after 4:00 p.m. If it rains 3-4 hours after spraying, supplementary spraying is required.
2) Prohibit use at high temperatures in the afternoon
Amino acid foliar fertilizer is a highly effective nutrient liquid component. Spraying foliar fertilizer in high temperature weather can cause nutrient evaporation and reduce nutrient concentration in rainy seasons, both of which significantly reduce the utilization rate of foliar fertilizer.
3) Prohibit use during seedling stage
3) Prohibit use during seedling stage
During the seedling stage, most crops are just beginning to germinate or should not be sprayed with foliar fertilizer immediately after transplanting.
At this time, the crops themselves are not only fragile, but also not so adapted to external conditions. Generally, spraying nutrient solution can easily lead to the phenomenon of burning seedlings and leaves, which is not conducive to the normal growth of seedlings.
