Problems solved by technology

[0002] The method for existing soybean somatic embryo regeneration plant, the rooting agent treatment technology method of soybean leaf stem node, inconvenience is applied in soybean breeding F 0 multiplication of generations
The success rate of soybean hybridization is low, and the obtained F 0 The amount of seeds is small, which seriously restricts the number of hybrid offspring populations, resulting in insufficient genetic recombination of hybrid offspring, and the number of isolated samples is relatively small, which affects the performance of offspring excellent plants and the effectiveness and progress of new variety selection

Embodiment 1

[0022] The cuttings are collected from the middle and upper parts of the main stems or branch stems with good growth and no occurrence of diseases and insect pests; processing of cuttings: the cuttings that are urgently needed for splicing are graded and bundled with the same thickness, and the cuttings are placed in order Keep fresh in water; cut the scion: the scion is 2-3cm long, and it is advisable to have a full bud. The two sides of the bud at the lower end of the scion are obliquely cut into a wedge-shaped section of about 0.5cm, so that the side with the bud is slightly thicker, and the other One side is slightly thinner, and the cut is required to be smooth and wedge-shaped; inserting scions: the principle is to use large spikes for large rootstocks, and small spikes for small rootstocks. Insert into the split opening, deep to the top of the slightly exposed surface, be sure to make sure that the cambium of the scion and the rootstock are aligned and connected, and the...

Embodiment 2

[0024]The cuttings are collected from the middle and upper parts of the main stems or branch stems with good growth and no occurrence of diseases and insect pests; processing of cuttings: the cuttings that are urgently needed for splicing are graded and bundled with the same thickness, and the cuttings are placed in order Keep fresh in water; cut the scion: the scion is 2-3cm long, and it is advisable to have a full bud. The two sides of the bud at the lower end of the scion are obliquely cut into wedge-shaped slices about 1cm long, so that the side with buds is slightly thicker and the other side is thicker. Slightly thinner, it is required to cut the edge smoothly into a partial wedge shape; inserting scions: the principle is to use large spikes for large rootstocks, and small spikes for small rootstocks. Insert into the opening, deep to the top of the slightly exposed chamfered surface, be sure to make sure that the cambium of the scion and the rootstock are aligned and conn...

Embodiment 3

[0026] The cuttings are collected from the middle and upper parts of the main stems or branch stems with good growth and no occurrence of diseases and insect pests; processing of cuttings: the cuttings that are urgently needed for splicing are graded and bundled with the same thickness, and the cuttings are placed in order Fresh-keeping in water; cutting the scion: the scion is 2-3cm long, and it is advisable to have a full bud. The two sides of the bud at the lower end of the scion are obliquely cut into a wedge-shaped section of about 0.7cm, so that the side with the bud is slightly thicker, and the other One side is slightly thinner, and the cut is required to be smooth and wedge-shaped; inserting scions: the principle is to use large spikes for large rootstocks, and small spikes for small rootstocks. Insert into the split opening, deep to the top of the slightly exposed surface, be sure to make sure that the cambium of the scion and the rootstock are aligned and connected, ...

Abstract

The invention relates to a soybean cultivation method, in particular to a soybean plant propagation expanding method. The method comprises the steps of nursery land selection, land preparation and fertilizer application, seed treatment, sowing, management of sowing seedlings, grafting and management after grafting. The grafting step comprises the sub-steps of scion topping, scion collection, rootstock cutting and splitting, scion chipping, scion cutting and binding; when plants grow 2-3 compound leaves, scion topping is conducted to break growing points of scions, apical dominance is reduced and the growth of side branches is promoted; according to the sub-step of scion collection, a section of young stem on the top of one compound leaf is cut out in a F0 hybrid plant or a soybean plant needing to expand propagation, and 1-2 leaf and stem sections are reserved; in the sub-step of rootstock cutting and splitting, cutting is conducted at the first compound leaf section of a selected cut-grafting rootstock, and oblique splitting is conducted at the leaf stalk and stem of the first compound leaf section in the direction facing the stem, and the depth is 0.6-1.0 cm; in the sub-step of scion cutting, scions identical in size are selected according to the degree of thickness of the rootstock, the side of the young stem at the lower end of each scion is obliquely cut into an oblique cutting surface with the length about 0.5-1.0 cm, and the oblique notch is smaller than a rootstock notch.

Description

technical field [0001] The invention relates to a method for cultivating soybeans, in particular to a method for multiplying soybean plants. Background technique [0002] The method for existing soybean somatic embryo regeneration plant, the rooting agent treatment technology method of soybean leaf stem node, inconvenience is applied in soybean breeding F 0 generational expansion. The success rate of soybean hybridization is low, and the obtained F 0 The small amount of seeds severely restricts the number of hybrid progeny populations, resulting in insufficient genetic recombination of hybrid progeny, and the number of isolated samples is relatively small, which affects the performance of excellent plants in future generations and the effectiveness and progress of new variety selection. Contents of the invention [0003] The object of the present invention is to provide a method for multiplying soybean plants, which can expand F 1 Seed quantity of generation hybrids, an...
