The greenhouse is cultivated for overwintering and then grafted cucumber seedlings. The cucumber seeds are sowed for 5-7 days. The cotyledon of the pumpkin is flattened until the first half of the true leaf is unfolded, and the cucumber 2 leaves are suitable for grafting. At present, there are 3 ways to raise cucumbers for wintering and picking cucumbers: First, cucumber and black-seeded squash were sown and nursed separately. When grafting, seedlings were dug separately, followed by another planting; The other is that in the sand bed sown with cucumber seeds, the black seed pumpkin is germinated and then sown into the nutrient bowl. Only the cucumber seedlings are excavated during grafting, and then the roots of the cucumber seedlings are planted on the side of the nutrient bowl. Into the seedbed for cultivation, according to the situation of moving seedlings to manage the transplant, when transplanting seedlings when transplanting is convenient, not easy to hurt the roots. In the third type, pumpkin seeds were directly sown on a ridge, and cucumber seedlings were taken out during grafting, and then the roots of the cucumber seedlings were planted on one side of the ridge. The three methods have advantages and disadvantages. They only require skilled grafting technology to ensure the survival rate of grafting. Do a good job after grafting, in the first 3 days after grafting, the temperature should be maintained at 25-30°C, and the humidity should be 90-95%. Afterwards, the temperature and humidity should be gradually lowered. After grafting, new high-fat membranes should be sprayed to moisturize, prevent infection, and improve graft survival. Rate, nurturing strong seedlings.
