Greenhouse cucumber grafting mainly adopts two methods of docking and docking.
There are several advantages compared to docking: First, simple operation, easy grafting, easy management, and early colonization; second, effective avoidance of secondary roots in cucumbers, and very good soil-borne diseases such as blight and blight. Good preventive effect; Third, due to the large knife-to-edge area, the melon seedlings are particularly prosperous in the early stages. In the docking process should pay attention to the following questions:
1, wrong period. Using plug, cucumber seedlings should be small, so that the transpiration of cucumber seedlings is weak afterwards and it is not easy to fight. Therefore, cucumber can be sown with pumpkin at the same time. Pumpkin cotyledons flattened for grafting.
2, nursery. Pumpkin can be grown on a semi-sand bed, or the pumpkin can be sowed directly in a nutrient bowl. In this way, the pumpkin does not slow down after grafting.
3, knife edge direction. The blade of the cucumber must be inserted downwards into the mouth of the pumpkin knife. The direction must not be reversed. The cucumber cotyledons and the pumpkin cotyledons should be cross-shaped.
4. Humidity in a small arch. The difference from the docking is that the relative humidity of the air should be kept at 100% for the first 2 days after insertion to ensure that the cotyledons of the cucumber do not fall apart. Should be followed by watering, with a small shed cover and shade, such as the lack of humidity in the greenhouse should be sprayed, 24 hours after a short time to release the wind and humidity.
5, nursery with nutrients, under the nutrition do not shop plastic sheeting.
