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 present invention discloses a hevea brasiliensis seedling bud rootstock grafting seedling bud-picking-free method and belongs to the technical field of bud grafting seedlings. The method comprisesthe following steps: (1) planting hevea brasiliensis seedling bud rootstock grafting seedlings after bud grafting in a plastic greenhouse and conducting topping when second or third cluster leaves ofthe seedling bud rootstock grafting seedlings are stable; (2) after topping, using a lamp above a seedling bud grafting stock to perform night lighting with a light intensity of 18,000-22,000 LUX; and (3) stopping night light supplement when first cluster leaves of scions of the seedling bud rootstock grafting seedlings are stable and conducting cultivation until moving out from gardens in the natural environment. The method does not need to pick buds, directly eliminates a bud-picking link, greatly reduces workload, and conducts light supplement at night after the topping, the seedling bud rootstock grafting seedlings can undergo photosynthesis within 24 hours, a photosynthetic product provides energy for growth of the first cluster leaves of the scions, and thus the method enables the seedlings to be strong, back-withering and mortality of the scions to be low and seedling rate to be high.

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...
