Grasp the time of flowering. When a tomato blooms, the opening time of the flowers on the same panicle is different, and the spraying of flowers cannot be "treated equally". The flowers near the spike stalk bloom first, followed by the middle of the spike and the tip of the spike. Due to the different spraying equipment used, the spraying equipment can generally be adjusted to be able to spray 3~4 flowers at the same time. If the spray area is too large, those flowers that have not yet opened close to the tip of the spike stick to the liquid and are prone to early stiffness and late cracking.
Grasp the environment of spraying flowers. Generally, the spraying operation is carried out once every 4~5 days, and the morning spraying is selected, and the temperature is controlled between 20 °C ~ 23 °C. The shed should have a good ventilation environment, and the size of the tuyere should ensure that the humidity in the shed is reduced to a suitable range, but the ventilation should not be too strong.
Accurately grasp the concentration of medication. The concentration of the agent is very critical when spraying flowers, a light concentration of the agent may lead to inability to sit still, and a high concentration of the agent will cause hormone poisoning. Gibberellin can be appropriately added to spray anthers to promote fruit expansion. In addition, disease prevention agents can be added to the anthers according to different seasons, such as in the season when gray mold is prone to occur at low temperature and high temperature in winter and spring, Suclin, iprodione and other agents can be added to prevent and control flower infection by disease.
Strict spraying operation. When spraying flowers with a flower sprayer, the liquid has a certain diffusion range, so it is necessary to block the liquid sprayed by hand. According to reports, when spraying flowers, the right hand holds the flower sprayer, the left hand holds up the flower spike, and sprays the target flower, and the focus of the spray should be on the sepals. A cotton glove can be worn on the left hand, and a layer of leather gloves can be added to the inside of the cotton glove to avoid the liquid medicine from contaminating the palm. After spraying for a period of time, the liquid absorbed in the cotton gloves can be wrung out, filtered and used again.
