Master the time to bloom. When the tomato blooms, the opening time of the flowers on the same ear is different, so spray flowers cannot be treated equally. The flowers near the stalk bloom first, then the middle and tip of the ear. As the spraying equipment used is different, generally the spraying equipment can be adjusted to be able to spray 3 to 4 flowers at the same time. If the spray flower area is too large, the unopened flowers close to the tip of the spike will tend to stiffen and crack in the evening. Grasp the environment for spraying flowers. Generally, the spraying operation is performed once every 4 to 5 days. When spraying, choose to spray in the morning, and the temperature is controlled between 20°C and 23°C. The shed must have a good ventilated environment, and the size of the air outlet must ensure that the humidity in the shed falls within the appropriate range, but it should not be ventilated too strongly. Strong wind will affect the spraying effect. Accurately grasp the drug concentration. The concentration of the medicament when spraying flowers is very critical. A light medicament concentration may lead to failure, while too high a medicament concentration may cause hormone poisoning. Appropriate addition of gibberellin to spray anthers can promote fruit enlargement. In addition, it is possible to add disease-preventing agents to the anthers according to different seasons. For example, in winter and spring when low temperature and high temperature are prone to gray mold disease, sukeling, iprodione and other agents can be added to prevent flowers from being infected by diseases. Strict spraying operation. When spraying flowers with a flower sprayer, since the liquid medicine has a certain diffusion range, it is necessary to block the sprayed liquid medicine by hand. According to reports, when spraying flowers, hold the flower sprayer in the right hand, hold the flower spikes in the left hand, and spray at the target flower. The focus of the spray flower should be on the sepals. A cotton glove can be worn on the left hand, and a layer of leather gloves can be added inside the cotton glove to prevent the liquid from contaminating the palm. After spraying for a period of time, the liquid medicine absorbed in the cotton gloves can be wringed out, filtered and used again.
