021. The application concentration and timing mainly depends on the local agricultural climate, the management status of the previous year and the purpose of application in the current year. The application concentration and time may vary from year to year. It is recommended to consult a technician before application or determine it based on local application experience. 2. Pour the required amount of product into the required amount of water, the normal dilution concentration is between 20-25 times (5-6.25 kg per bottle of water, 20 times that has not passed dormancy or about 18 times according to experience; 25 times that have passed partial dormancy, if applied to green branches to induce secondary fruit, the concentration can be appropriately reduced); the specific usage amount is determined according to the application experience of local technicians, and fully stirred After uniformity, apply (or spray) the prepared solution directly to the dry shoots with a cotton ball (or brush, sprayer), etc., to completely cover all dormant buds and branches. Apply buds and branches to ensure that the buds are treated. Water 1-2 days before application. 3. Select the appropriate application time according to different cultivation modes. (1) Greenhouse, greenhouse insulation cultivation: It is recommended to apply it 5 days before the shed is closed (if the shed has been buckled, it is recommended to apply it within 2 days after the shed is buckled. (If used in a shed, be careful to keep the temperature no more than 25 degrees in the first 2 canopies after applying buds, and be careful to increase the physiological moisture of the shoots). Apply sprouts or spray with 20-25 times the liquid of this product, ready to use. It must be watered before using the medication. (2) Open field cultivation: Frost-free areas in the south can be applied after the grapes fall leaves, regardless of the time limit. Less frost areas in the south should be applied after the frost period to avoid premature germination and freezing damage. The Yangtze River Basin and areas north of it generally end use in time 20-30 days before normal germination. Apply sprouts or spray with 20-25 times the liquid of this product, ready to use. Wet soil must be watered before medication Tips: 1. The soil must be moist before applying buds, and the branches have sufficient physiological moisture. If there is a long-term drought, water 1-2 days in advance, and spray the branches with water, and then apply sprouts after drying. 2. Pay attention to checking the weather forecast to ensure that there is no rainfall within 24 hours after Tu Ya. If there is rain within 24 hours after applying the buds, the effect of spraying will be reduced. Reapply the buds and rods that have been exposed to rain. 3. When using this product, the natural temperature (in the shed) should not be less than 5 degrees, and the soil moisture should be maintained; if insulation cultivation has begun to be kept warm, the initial temperature should be controlled below 20 degrees to avoid burning buds. At the same time, in addition to maintaining soil moisture, air humidity should be maximized to facilitate faster and tidy germination
