At present, there are many vegetable growers who choose to spray flowers. Compared with the point flower, the spray is labor-saving and labor-saving. However, if the spray operation is not proper, many problems may occur. If the actual parameters are uneven, the fruit is abnormal, and the fruit is uneven. Waiting for the situation. Remind the vegetable growers that the spray technique requires four key points. Mastering the time of flowering When the tomato is flowering, the opening time of the flowers on the same ear is different, and the spray can not be treated as "one person." The flowers near the stem are opened first, followed by the ear and the tip of the ear. Due to the different spray equipment used, the spray equipment can generally be adjusted to spray 3-4 flowers at the same time. If the area of ​​the spray is too large, those flowers that are not open to the tip of the ear stick to the liquid and are prone to early stiffness and cracking. Grasp the environment of the sprayed flower. Generally, the spray operation is carried out once every 4-5 days. When spraying, choose spray in the morning, and the temperature is controlled between 20-23 °C. The shed should have a good ventilation environment. The size of the vent should be such that the humidity in the shed is reduced to a suitable range, but the ventilation cannot be too strong. The strong wind force during the spraying will affect the spray effect. Accurate drug concentration The concentration of the drug at the time of spraying is very critical. The light concentration of the drug may cause the fruit to be unsatisfied, and the concentration of the drug is too high, and hormone poisoning may occur. In the spray medicine, gibberellin can be appropriately added to promote fruit enlargement. In addition, according to different seasons, anti-disease agents can be added to the anthers in the same period. For example, in the season of low-temperature and high-temperature prone to gray mold in winter and spring, agents such as kelican and iprodione can be added to control the infection of flowers by diseases. Strict spray operation When spraying with a sprayer, the liquid medicine has a certain diffusion range, so it is necessary to block the sprayed liquid by hand. According to reports, when spraying, the right hand holding the sprayer, the left hand holding the flower spike, aiming at the target flower spray, the focus of the spray should be placed on the bract. 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 of the hand. After spraying for a period of time, the liquid absorbed in the cotton glove can be screwed out, filtered and used again. Disclaimer: Some articles on this website are transferred from the Internet.
