Since the greenhouse cucumber cannot be turned down, grafting technology can prevent blight.
Grafting method: Seeding period depends on the seedling age and the duration of planting. Cucumber seeds are sowed five to seven days earlier than the pumpkin seeds. About 15 days after the cucumbers are sown, the cucumber seedlings are changed from yellow to green and fully expanded. The second leaf is true. When the twilight was revealed, the leaves of the pumpkin seedlings spread out, and the first true leaf was the best time for grafting. First, use bamboo sticks to dig out the growing point of the pumpkin seedlings, then cut a 45-degree incision in the upper part of the pumpkin seedlings about 1 centimeter from the cotyledon, and the mouth depth is about two-thirds of the stem diameter, and then use the blade. Cut the upper part of the cucumber about 1.5 centimeters from the cotyledon up 45 degrees incision, the depth is about two-thirds of the stem, after the two melon seedlings are cut, then the cucumber seedlings are aligned to the cut surface of the pumpkin seedlings Plug in well, leave no gaps in the incision, and then use the graft clamp to get close to the side of the cucumber seedlings. When grafting, do the following: Accurate, fast, and clean.
