Problems solved by technology

The seeds of Begonia four seasons are small and have a short lifespan. The seeds that naturally fall into the pot soil often germinate quickly and grow seedlings, but if the harvested seeds are not sown in time, there are very few seedlings.
However, during the cutting process of Begonia four seasons, it is very easy to cause low rooting rate and slow rooting, and even cause a lot of rot.
Most of the existing technologies use the method of thoroughly disinfecting the cuttings, which can improve the above problems to some extent, but it will damage the branches and cannot completely prevent the infection of pathogenic bacteria.

Embodiment 1

[0031] A cutting propagation method of Begonia four seasons, which comprises the following steps:

[0032] Select the annual double-petaled Begonia branches with top buds with short internodes, strong buds and thick, healthy, disease-free and pest-free as cuttings. First remove the lower leaves, and use a blade to flatten the cutting base 1 cm below the node. The length of the strip is 8cm, and the cutting can be completed within 12 hours; the cutting time is September 10; the variety of Begonia is Double Four Season Begonia;

[0033] Soak the lower part of the cuttings in the compound solution, the soaking depth is 3cm, and the soaking time is 40s;

[0034] Mix the river sand and loess according to the mass ratio of 1:1 to obtain the substrate, then use a small bamboo stick to the substrate hole, and then slowly send the cuttings into the hole, insert the substrate to a depth of 3cm, and water after it is solid; Put on a plastic bag with holes to moisturize. In the light management...

Embodiment 2

[0040] A cutting propagation method of Begonia four seasons, which comprises the following steps:

[0041] Select the annual double-petaled Begonia branches with top buds with short internodes, strong buds and thick, healthy, disease-free and pest-free as cuttings. First remove the lower leaves, and use a blade to flatten the cutting base 1 cm below the node. The length of the strip is 7cm, and the cutting can be completed within 12 hours; the cutting time is September 15; the variety of Begonia is Double Four Season Begonia;

[0042] Soak the lower part of the cuttings in the compound solution, the soaking depth is 2cm, and the soaking time is 60s;

[0043] Mix the river sand and the loess according to the mass ratio of 1:1 to obtain the matrix, then use a small bamboo stick to the matrix hole, and then slowly send the cuttings into the hole, insert the matrix to a depth of 2cm, and water after it is solid; Put on a plastic bag with holes to moisturize. In the light management, cho...

Embodiment 3

[0049] 1. Take the method of Example 1 as an example to test the effects of different auxins on rooting, set different concentrations, select the commonly used auxins NAA and IBA, the number of cuttings in each group is 100, see Table 1:

[0050] Table 1

[0051] Auxin type

[0052] It can be seen from Table 1 that the root-promoting effect of IBA auxin is better, better than NAA, and the concentration of 10-20mg / L is more appropriate.

[0053] 2. Take Example 2 as an example to test the influence of different soaking time on rooting. The soaking time is 0s, 20s, 40s, 60s, 80s, and the number of cuttings in each group is 50. See Table 2:

[0054] Table 2

[0055] Soaking time s

[0056] It can be seen from Table 2 that when the soaking time is 40-60s, the number of roots is the largest, and the average number of roots / branch and the longest root length are better than other groups.

[0057] 3. The influence of different types of compound solutions on rooting:

[0058] Take Example 1...

Abstract

The invention belongs to the technical field of plant seedling reproduction, and discloses a cutting cultivation method for wax begonias. The cutting cultivation method includes selecting one-year-oldhealthy twigs, free from plant diseases and insect pests, with terminal buds, short internodes, strong sprouts and branches, cutting the twigs, pinching off lower leaves, and flattening the lower sides of node orders of bases of the twigs by a blade; soaking the lower portions of cuttings in a composite solution for more than 30 seconds; inserting the cuttings into holes after soaking, and watering the cuttings after compacting; covering the cuttings with plastic bags with holes for moistening, selecting a shading net with the light transmittance of 70% for lighting management, checking rooting conditions, and performing transplant. The cutting cultivation method has the advantages of vigorous growth of root systems, high quantity of roots and high survival rate.

Description

Technical field [0001] The invention belongs to the technical field of plant seedling propagation, and particularly relates to a cutting propagation method of Begonia four seasons. Background technique [0002] Four seasons Begonias belong to the Begoniaceae family, and Begonia is a succulent herb. The root is fibrous; the stem is upright, fleshy, glabrous, and the base is branched and leafy. The leaves are ovate or broadly ovate, the base is slightly slanted, and the edges are serrated and eyelashes. Both sides are bright and green, but the main veins are usually reddish. Native to Brazil. Four-season Begonia is a more common and cultivated species of Begonia plants. It has a graceful posture, delicate and bright leaves, clusters of flowers, blooming in all seasons, and a slight fragrance. It is one of the main potted flowers for indoor and outdoor decoration. People apply it to the arrangement of flower beds with excellent results. With the emergence of some relatively hea...
