Problems solved by technology

[0006] Aiming at the problem of difficult reproduction of male sterile line of broccoli, the present invention provides a method for raising seedlings by cuttings of broccoli, in which clustered buds of male sterile plants of broccoli are used as cuttings for cutting seedlings, and the clustered buds are converted into production-applicable Plants turn waste into treasure, improve utilization efficiency, and reduce seedling cost by more than 30%

Embodiment 1

[0029] 1) Select a plot with fertile soil and good terrain to plan a cutting seedbed. The seedbed extends from east to west. The bed surface is 1.3m wide and 5m long. The bed surface is slightly higher than the surface. The surface substrate of the seedbed is mainly Pin’s vegetable seedling substrate, supplemented by river sand, the volume ratio is 4:1, mixed evenly, and spread on the surface of the seedbed with a thickness of about 5cm. The substrate prepared by the two has good air permeability and water retention.

[0030] 2) The arch shed is made of steel bars (or bamboo chips), with a height of 0.8m, a width of 1.4m and a length of 5m. The arch shed is covered with double-layer polyethylene non-drip film, and a shade shed is set up at a distance of about 0.45m from the top of the arch shed. The shade shed is composed of iron brackets, iron wires and black sunshade nets.

[0031] 3) At the beginning of June, select the clustered shoots of broccoli male sterile plants that...

Embodiment 2

[0038] Select the broccoli male sterile line plants with semi-lignified broccoli clustered buds to make cuttings, the cuttings are about 6cm long, the surface substrate of the seedbed is based on Pin's vegetable seedling substrate, supplemented by river sand, its volume ratio is 4:1, mixed Evenly, spread on the seedbed surface, about 6cm in thickness, the insertion depth of cuttings is about 3cm, and other operations are with embodiment 1.

[0039]Through this embodiment, the survival rate of clustered buds of broccoli is as high as 95%, and the growth of the plants in the field is not significantly different from that of seedlings. The results are shown in Table 1.

Embodiment 3

[0041] Select the broccoli male sterile plants that were lignified in the same year to make the cuttings. The cuttings are about 14cm long. , tiled on the surface of the seedbed, about 7cm in thickness, and the insertion depth of the cuttings is about 5cm, and other operations are the same as in Example 1.

[0042] Through this embodiment, the survival rate of clustered buds of broccoli can reach 96%, and the growth of the plants in the field is not significantly different from that of seedlings. The results are shown in Table 1.

Abstract

The invention discloses a method for raising seedlings of broccoli by cutting. The method comprises the following steps: (1) cluster buds of broccoli male sterile line plants are taken as cuttings, after being subjected sterilization and root promotion substance processing, the cuttings are inserted into a cutting seedbed, water is evenly sprinkled for thoroughly irrigating the cutting seedbed; (2) after cutting, the germicidal treatment is performed on the cutting seedbed, and periodical fertilization is carried out, after the cuttings take roots, seedlings are obtained; (3) the obtained seedlings are subjected to hardening seedling and temporary planting, and then are transplanted to a field. According to the invention, the method that using the cluster bud cutting for propagation is adopted, the cluster buds are converted into plants applied to production, and the waster is turned into change waste into treasure, so that the utilization efficiency is improved, the seedling raising cost is reduced by 30-50 percent, and the economic benefit is obvious.

Description

technical field [0001] The invention relates to a method for raising seedlings by cuttings, in particular to a method for raising seedlings by cutting buds of broccoli male sterile lines. Background technique [0002] Broccoli is a variety of Brassica oleracea in the family Brassicaceae. Its edible organs are curds. It is native to the Mediterranean coast and was introduced to southern my country in the 19th century. Because of its tenderness, juiciness and delicious taste, it is deeply loved by consumers. It occupies an important position in my country's vegetable cultivation and annual supply. [0003] At present, broccoli breeding mainly uses the method of male sterile lines to prepare the first generation of hybrids. The use of cytoplasmic male sterile lines to prepare hybrids can not only overcome the shortcomings of self-incompatible lines such as high cost of artificial pollination and reproduction at the bud stage, long-term continuous self-fertility decline, and the...
