Because greenhouse cucumbers can't be used for cropping, grafting technology can be used to control blight.
Grafting method: depending on the length of the seedling and the planting period, the cucumber seeds are planted 5 to 7 days earlier than the pumpkin seeds, and about 15 days after the cucumber is planted, the cucumber seedling leaves turn from yellow to green, fully unfolded, and the second true leaf When it is slightly exposed; the pumpkin seedlings are unfolded, and the first true leaf is revealed as the best time for grafting. First, use bamboo sticks to dig up the growth point of pumpkin seedlings, and then use a blade to cut a 45-degree incision downward from the cotyledons about 1 cm in the upper part of the pumpkin seedlings. The mouth depth is about two-thirds of the stem diameter, and then the blade is used. The upper part of the cucumber is cut obliquely by a distance of about 1.5 cm from the cotyledons to a 45-degree incision. The depth is about two-thirds of the thickness of the stem. After the two melon seedlings are cut, the cucumber seedlings are aligned with the cut surface of the pumpkin seedlings. Inserted well, there is no gap in the incision, and then fixed with the grafting clip and close to the side of the cucumber seedling. When grafting, we strive to achieve: accurate, fast and clean.
