Prevent vegetable defoliation
1. In the days before harvesting, the cabbage is evenly sprayed with 2,4-D sodium salt solution in the field at the rate of 100 mg of 2,4-D sodium salt per kilogram, which can extend the cold storage period by 3 months. No defoliation. 2. Although the edible part of cauliflower (cauliflower) is not a leaf, the leaves around the ball can keep it fresh. Three to five days before harvest, the 2,4-D sodium salt is formulated as an aqueous solution per 100 kg of 2,4-D sodium salt per cauliflower, and then sprayed onto the cauliflower leaves (do not spray on flowers) Above the ball, it can significantly delay the defoliation time of broccoli during storage and even harvest it 1 day after spraying, which has the same effect. 3. In the 3 to 7 days before the Chinese cabbage is harvested, the 2,4-D sodium salt is formulated as an aqueous solution per kg of Chinese cabbage with a standard of 50 mg of 2,4-D sodium salt, or as per kg of Chinese cabbage. The naphthalene acetic acid standard of 220 milligrams was formulated with naphthalene acetic acid as an aqueous solution and sprayed in the field until the outer leaves were completely wetted. It can also be treated with these agents after harvest, but the drug concentration should be higher. Nanjing Superyears Gene Technology Co., Ltd. , https://www.superyearsglobal.com
