Embodiment 1

[0017] (1) Choose a plot with fertile soil and good terrain to plan the cutting seedbed. The seedbed is extended 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, its volume ratio is 4:1, mixed evenly, and spread on the surface of the seedbed with a thickness of 4-7cm. The substrate prepared by the two has good air permeability and water retention;

[0018] (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 about 0.4-0.5m away from the top of the arch shed. The shade shed is composed of iron brackets, iron wires and black sunshade nets;

[0019] (3) At the beginning of June, select the lignified (or semi-lignified) cauliflower cluster shoots...

Embodiment 2

[0026] The false planting and field planting time are selected from late November to early December. The time of cutting and transplanting at this time is later than in Example 1, and the remaining operations of the seedling raising process are the same as in Example 1. If the transplanting time is late, the plants will grow stronger and can be directly planted in the breeding field without false planting.

Abstract

The invention discloses a method for cutting and seedling raising of cauliflower male sterility line cluster buds. The method comprises the following steps of selecting a plot with fertile soil and good terrain to plan a cutting seed bed, and adopting a seedling culture matrix and river sand as a cutting matrix; selecting the current-year semi-lignified cluster buds as cutting slips, performing disinfection, sterilization and promotion of root forming substance treatment and then inserting the cutting slips into the seed bed; performing cutting and then performing disinfection, sterilization and fertilizer application, controlling temperature in a greenhouse and performing conventional management; performing transplanting and heeling after rooting and seedling hardening of plants and planting the plants in a large land after the plants grow healthy and strong. The survival rate of the cauliflower cluster buds obtained by means of the method reaches to 82.5%, and the growing situation of the plants in the land is not obviously different from seedling of seeds.

Description

technical field [0001] The invention relates to a method for raising seedlings by cuttings, in particular to a method for raising seedlings by cuttings of male sterile lines of cauliflower, belonging to the field of plant tissue culture. Background technique [0002] Cauliflower is a variety of Brassica oleracea in the family Brassicaceae. Its edible organ is curd. 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 vegetable cultivation and annual supply in my country. [0003] The method of cutting propagation is one of the important technical means of plant vegetative propagation, which has the advantages of small variability, easy rooting, high survival rate, and abundant sources of cuttings. The key to cutting propagation lies in two aspects: one is the permeability and water content control of...
