Greenhouses were cultivated for overwintering and then grafted cucumber seedlings. The cucumber seeds were sown 5-7 days earlier. The pumpkin cotyledon was flattened until the first half of the true leaf was unfolded, and the cucumber 2 leaves 1 heart was the appropriate time for grafting. At present, there are 3 ways to raise cucumbers for wintering and picking cucumbers:
1 Cucumbers and black-skin squash were sown and nursed separately. When grafting, seedlings were dug separately and then planted again.
2 In the sand bed sown with cucumber seeds, the black seed pumpkin was germinated and then seeded into the nutrient bowl. Only the cucumber seedlings were excavated during grafting, and then the roots of the cucumber seedlings were planted on the side of the nutrient bowl and placed on the seedbed for cultivation. , According to the seedlings mobile nutrition management, planting seedlings easy to move, not easy to hurt the roots.
3 The pumpkin seeds were sown directly on the ridge and the cucumber seedlings were picked up during grafting, and then the roots of the cucumber seedlings were implanted on the side of the ridge.
Note: In the first 3 days after grafting, the temperature is maintained at 25-30°C and the humidity is 90-95%. After that, the temperature and humidity are gradually decreased. After the grafting, a new high-fat membrane is applied to incubate and moisturize, prevent infection, increase graft survival rate, and cultivate robust seedlings. .
