There are two application methods of seaweed fertilizer foliar feed, foliar spraying and root irrigation, and foliar spraying is better than root irrigation. So what should be paid attention to in foliar spraying?
First, the concentration of foliar spraying seaweed fertilizer should be appropriate. Within a certain concentration range, the speed and quantity of nutrients entering leaves increase with the increase of solution concentration, but too high concentration is prone to fertilizer damage, especially trace element fertilizer. Generally, the use concentration of large and medium-sized elements (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) is 500 to 600 times, and the use concentration of trace elements iron, manganese and zinc is 500 to 1000 times.
Secondly, the time of spraying seaweed fertilizer on the leaves should be appropriate. When foliar fertilization, the longer the wetting time, the more nutrients absorbed by leaves, and the better the effect. Generally, it is appropriate to keep the leaves moist for 30 to 60 minutes, so the foliar fertilization is best carried out in the windless weather in the evening; Spraying fertilizer in the morning with dew will reduce the concentration of solution and affect the effect of fertilization. Foliar topdressing cannot be carried out in rainy days or before rain, because nutrients are easy to be leached and can not achieve the desired effect. If it rains 3 hours after spraying, it shall be sprayed again in sunny days, but the concentration shall be reduced appropriately.
Thirdly, the spraying shall be uniform, meticulous and thoughtful. Foliar fertilization requires fine droplets and uniform spraying, especially the vigorous upper leaves and the back of leaves.
The times of spraying seaweed fertilizer shall not be too few, and there shall be intervals. The concentration of foliar Topdressing of crops is generally low, and the amount absorbed each time is very small, which is much lower than the demand of crops. Therefore, the number of foliar fertilization should generally not be less than 2 to 3 times. At the same time, the interval shall be at least one week, and the spraying times shall not be too many to prevent harm.
