In the fruit period, the growth of the big trees is moderated. Due to a large number of results, the branches droop and the thin and weak branches are not likely to form flower buds. Pruning should be based on the principles of proper cutting, cutting with strong branches, cutting with weak branches, cutting with weak branches, but not dense, and regulating the relationship between growth and results, and maintaining robustness and prolonging fruitful years. Prolonged branches of the main lateral branch are aggravated by short cuts, and generally cut 1/2 to 2/3. With the main branch pendulous, select a strong branch from the back for the branch and remove the original branch. Perennial branching and pendulous branches should be retracted in branches with strong twigs or multiple buds, and the long and middle branches that are planted on them should be short-cut, partially slow-relieved, and partially yielded to ensure production. The long and middle fruit branches in the canopy are more short-cut, less slowly put, and the perennial branches of the canopy are partially retracted, allowing the branches to be retracted and retracted.
Care should be taken to prevent pests and diseases during the flowering of grapes. Pests and diseases that damage leaves, buds, and fruits include downy mildew, anthracnose, blackpox, scab, acid rot, aphids, and red spiders. Most of them come from overwintering pests, If these overwintering pests can be eradicated in time, the temperature will rise again in the second year, and after flowering, the buds, fruits and leaves will be lightly damaged by pests and diseases. Therefore, we must pay attention to prevention and control of overwintering pests after falling leaves.
The specific prevention and control methods are as follows: After the winter deciduous leaves, the clear garden will be cleared in time to remove all the weeds and litter and fruit in the orchard, and to focus on deep buried or burned outside the park. Then spray 2-3 times 1500 times 3.2% avermectin, 1000 times 80% thiophanate-methyl mixture, or 1500 times 48% chlorpyrifos, 1000 times 80% carbendazim mixture, or 0.8-1 Baume Degree of lime sulfur solution, spray once every 15-20 days, evenly wet all stems in order to start dropping drops is appropriate. In order to improve the control effect, do not spray on windy weather. Within four hours after spraying, rainwater should be flushed.
IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor. With a micro size of 46x17x7mm, customers can widely use in many Laser Measurement Solutions. The lidar distance sensor can measure 12m short-range with high frequency up to 100hz. It's great for Unmanned Aerial Systems. If you need us send you data sheet and spec for this products, offering sample as well, pls tell us, thank you.
