Embodiment 1
[0033] A kind of rubber tree seedling bud grafting rootstock seedling avoids the method for smearing bud, comprises the steps:
[0034] (1) sow rubber tree seeds, treat the seedlings to grow for more than 20 days, and carry out seedling budding when the first pair of blades are not unfolded, and the rubber tree seedling budding rootstock seedlings that complete the budding are planted in plastic greenhouses, and the seedling budding rootstock seedlings are planted in plastic greenhouses. When the 2nd or 3rd awning leaves are stable, topping is carried out, and the topping is to cut the anvil at 1.0cm below the first pair of leaves of the rootstock seedlings after seedling budding, and remove the top part; the scion is Reyan 7-33-97 or Clonal bud slices of Reyan 7-20-59;
[0035] (2) After topping, use lamps for night illumination on the second day, and use lamps for night illumination above the seedling budding piles. The distance between the lamps and the seedling budding pil...
Embodiment 2
[0038] On the basis of embodiment 1, topping in step (1) is to cut the anvil at 0.5cm below the first pair of blades of rubber tree seedling budding rootstock seedling, remove the top part, in step (2), the lamp distance from seedling The distance between the budding piles is 50cm, the light intensity is 20000LUX, and all the other steps are the same as in Example 1.
Embodiment 3
[0040] On the basis of Example 1, topping in step (1) is to cut the anvil at 0.2cm below the first pair of blades of the seedling budding rootstock seedling, remove the top part, and in step (2), the distance between the light fixture and the seedling grafting The distance of bud pile is 60cm, and light intensity is 22000LUX, and all the other steps are all the same as embodiment 1.
[0041] In the foregoing embodiment, during the whole seedling cultivation period, in order to prevent powdery mildew, it is necessary to spray sulfur powder water solvent on seedlings.

Abstract
The invention discloses a method for budding rootstock seedlings of rubber tree seedlings without wiping buds, belonging to the technical field of budding seedlings. When the 2nd or 3rd leaf is stable, the seedlings are topped; (2) After topping, a lamp is used to illuminate the top of the seedling budding pile at night, and the light intensity is 18000‑22000LUX; (3) The seedling budding is connected The scions of the rootstock seedlings stop filling light at night when the first leaf is stable, and cultivate the nursery in the natural environment. The application does not need to wipe buds, directly eliminates the link of wiping buds, and greatly reduces the workload. After topping, the light is supplemented at night, and the seedling buds can be photosynthesized for 24 hours after being connected to the rootstock and seedlings. The growth provides energy, so as to achieve strong seedlings, low scion wilting and low mortality, and high seedling rate.
Description
technical field [0001] The invention belongs to the technical field of budding seedlings, and more specifically relates to a method for budding rootstock seedlings of rubber tree seedlings without smearing. Background technique [0002] Rubber tree budding seedlings are the most important planting material for rubber tree commercial cultivation, accounting for more than 99%. Budding of rubber tree seedlings is the main type of budding seedlings, accounting for the vast majority of rubber planting areas in Yunnan and Guangdong. The rubber tree seedling budding seedling cultivation technology is mainly as follows: about 25 days after the rubber seed germination, the seedlings are pulled out from the sand bed, and then transplanted on the seedling bag after indoor budding. For the leaves, the tops are picked above the first pair of leaves, and at the same time, the two side buds of the leaves need to be wiped off to eliminate the dominance of the tops, so that the scion buds c...
