Problems solved by technology

Its disadvantage is that the anvil is broken by hand or by a small saw blade due to uneven force, resulting in different depths of the anvil. Either the depth is not enough and the rootstock grows back, and the budding does not take place; The buds are pulled out quickly, and the roots and stems have insufficient nutrients in their own reserves and gradually wither; the common result is that the buds are slow and irregular or the buds are quickly withered
[0006] In the process of promoting the germination of seedlings, no matter which method is adopted, it requires high experience and technical requirements. When large-scale seedlings are raised, it will inevitably cause high labor costs and low efficiency. Otherwise, it is easy to cause the buds to fail to germinate. , slow germination or germination back to dry and other consequences, even if the seedlings germinate and germinate, there will be uneven germination time and uneven growth, which will affect the follow-up management measures, resulting in low seedling emergence rate and rubber seed failure. Poor quality of seedlings

Embodiment 1

[0017] In March 2013, a batch of rubber seedlings were budded (small tube seedlings, weighing about 0.5kg), and in June 2013, they were selected in a nursery greenhouse (with shade but no rainproof function, and the light intensity was 50% of outdoor) 360 rootstocks with two stable seedling buds (the rootstock is turquoise below the first leaf), 180 of which carry out conventional acupuncture and bud removal and leave two true leaves, which are germinated by conventional methods (contrast , marked as CK), another 180 directly cut the top into light rods with scissors at the 0.5cm place below the first fluffy leaves, adopt the following method of the present invention to cultivate scion growth (marked as A):

[0018] Top-cutting pre-treatment: in the first 20 days before the top-cutting, the water and fertilizer (N:P:K:Mg=10:10:4:1.5) with a fertilizer content of 2% were applied to the roots of seedling sprouts twice;

[0019] Cut the top and seal the wound: after the rootstock...

Embodiment 2

[0027] In October 2012, a batch of rubber seedlings were budded (small seedlings in bags, weighing about 3kg), and after wintering, 60 rootstocks were selected from the outdoor nursery (no shade and no rainproof function) in May 2013. Stable seedling bud grafting (its rootstock is semi-lignified below the first fluffy leaves, i.e. half-brown and half-green), wherein 20 strains are carried out with conventional acupuncture and sprouting to leave two true leaves, and adopt conventional methods to germinate ( Contrast, marked as CK), another 40 directly cut the top into light rods with scissors at the 0.5cm place below the first fluffy leaves, adopt the following method of the present invention to impel germination growth (marked as A):

[0028] Top-cutting pretreatment: before preparing to cut the top 15 days, it is 2% water and fertilizer (N:P:K:Mg=10:10:4:1.5) twice that fertilizer content is applied to the root of seedling bud grafting;

[0029] Cut the top and seal the wound...

Embodiment 3

[0037] In March 2013, a batch of rubber seedlings were budded (small tube seedlings, weighing about 0.5kg). In June 2013, 100 seeds with weak growth of rootstock were kept in the nursery greenhouse (with shade but not rainproof function). The seedlings were inoculated without any treatment, and only water and fertilizer (N:P:K:Mg=10:10:4:1.5) with a fertilizer content of 2% were applied twice in the growing season of the year; The 0.5cm place below the leaf scar directly cuts the top into a polished rod with scissors, and adopts the following method of the present invention to impel germination growth:

[0038] Top-cutting pre-treatment: in the first 15 days before the top-cutting, the root application of fertilizer with a fertilizer content of 2% (N:P:K:Mg=10:10:4:1.5) twice; The lower part of the first leaf is lignified (brown) or semi-lignified (half brown, half cyan);

[0039] Top cutting and wound sealing: Cut the top when the temperature rises above 20°C: Use sharp scis...

Abstract

The invention relates to a method for increasing the budding and growing consistency of bud grafting seedlings of rubber seeds. The method is characterized in that bud grafting is carried out by taking rubber seedlings which are germinated for1-2 weeks, the top parts of root stocks are cut when second cluster leaves are stable, and water and fertilizer are applied to the root parts of the root stocks before the top parts of the root stocks are cut; after the top parts of the root stocks are cut and before the bud grafting is carried out, culture substrate in a seedling culturing container is maintained to be wet, the water and the fertilizer are applied to root parts of the bud grafting seedlings until the bud grafting seedlings are budded, seedling-strengthening water and fertilizer are applied to the root parts of the bud grafting seedlings after the bud grafting seedlings are budded and leaves are unfolded, and glycine solution is sprayed and applied to the leaf surfaces; after grafted first cluster leaves are stable, and the water and the fertilizer are applied to the root parts of the root stocks until the bud grafting seedlings can be selectively taken out from a nursery after the second cluster leaves are stable; disease and insect damage prevention management is carried out during the period. According to the method for increasing the budding and growing consistency of the bud grafting seedlings of the rubber seeds, disclosed by the invention, the operation is simple and convenient, the efficiency is high, a top advantage removing measure is combined with a tube stroking measure, the problems that the bud grafting seedlings are withered and the budding growth is irregular are effectively solved, the budding and growing consistency of rubber bud grafting seedlings is promoted, convenience is provided for a follow-up growth management, the seedling culturing production cycle is shortened, the seedling culturing production efficiency is increased, and the quality of a nursery stock is increased.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a method for budding and growing of rubber seedlings, in particular to a method for improving the consistency of budding and growing of rubber seedlings. Background technique [0002] Bud grafting of rubber seedlings is a relatively new type of seedlings. Bud grafting is carried out on seedlings 1 to 2 weeks after germination. After the bud grafting survives, the top advantage is removed, and the buds are pulled out. When they grow to 2 to 3 leaves, they can go out of the nursery. It has the characteristics of short seedling cycle, high land utilization rate, convenient transportation, complete root system, vigorous growth, and fast recovery after planting. [0003] After the budding seedlings are untied, in the process of prompting the buds to germinate and pull out, it is necessary to keep the two true leaves of the rootstock's first fluffy leaves (the leaves can continu...
