Pay attention to the following points in the cultivation method of wintering glutinous grafted cucumber seedlings:
The greenhouse is cultivated for wintering and grafting of cucumber seedlings. The cucumber seeds should be planted 5-7 days earlier. The pumpkin cotyledons are flattened to the first true leaf and semi-expanded. Cucumber 2 leaves and 1 heart are the appropriate period for grafting. Linyi Fertilizer Network Copyright
At present, there are three ways to feed the wintering cucumbers: one is to plant the seedlings of cucumber and black seed pumpkin, and the seedlings are separately picked up after grafting, and then planted separately; the other is the sand bed spread by cucumber seeds. In the middle, the black seed pumpkin is germinated and then sown into the nutrient mash. When grafting, only the cucumber seedlings are burrowed. After the grafting, the roots of the cucumber seedlings are planted on the side of the nutrient mash, and placed in the seedbed for cultivation, and the nutrition can be moved according to the seedling condition.钵 Management, seedlings are easy to handle when planting, not easy to damage the roots. The third type is to plant the pumpkin seeds directly on the ridges of the ridges, and to pick up the cucumber seedlings when grafting, and then the roots of the cucumber seedlings are planted on the side of the ridges. Each of the three methods has its advantages and disadvantages, and only requires grafting technology to ensure the graft survival rate. After grafting work, the temperature should be maintained at 25-30 °C for the first 3 days after grafting, and the humidity will be 90-95%. Afterwards, the temperature and humidity will be gradually reduced. After grafting, the new high-fat film will be sprayed in time to keep moist and moisturize, prevent infection and improve grafting survival rate. To cultivate robust seedlings.
