Problems solved by technology

However, the quality of seed bulbs is good; the bulbs formed by method 2 are small and poor in quality, and the cycle of forming commercial bulbs is long, so it is rarely used in production; method 3 has high requirements and large investment, and the quality of bulbs is not as good as that of side bulbs. The increase in the number of generations increases the mutation rate and causes the species to degenerate; method 4 can only be used as a supplement to other breeding methods
In short, there are still many problems in large-scale breeding, especially in the unification of multiplication coefficient, cost and quality.

Embodiment 1

[0019] One- and two-year-old narcissus bulbs were harvested from the field at the beginning of June, dried in the shade and then stored in bags, and placed at a low temperature of 4-10 °C for one month; The center of the disc is a dot, and the bulbs are radially cut longitudinally into uniform small pieces, each with a bulb disc and all scales; the cut pieces are mixed with wet fine sand, put into a plastic bag and sealed and stored in a dark place; 1 A month later, small bulbs will be formed on each bulb cut, and the grown small bulbs will be separated one by one, and transplanted to the open field.

Embodiment 2

[0021] One- and two-year-old narcissus bulbs were harvested from the field at the beginning of June, dried in the shade and then stored in bags, and placed at a low temperature of 4-10 °C for one month; The center of the disc is a dot, and the bulbs are radially cut into even small pieces longitudinally, each piece retains the disc with bulbs and all scales; the cut bulbs must be cut into pieces and ventilated for several hours before mixing with washed wet fine sand. Put it in a plastic bag and seal it and store it in a dark place. Open the bag once every 15 days to ventilate it; after 1 month, small bulbs will be formed on each bulb cut into pieces.

Embodiment 3

[0023] One- and two-year-old narcissus bulbs were harvested from the field at the beginning of June, placed in bags and placed at a low temperature of 4-10 °C for one month; the bulbs that had been treated at low temperature were taken out, and the bulbs were cut radially longitudinally with the center of the bulb disc as a dot at room temperature. Evenly small pieces, each with bulb disc and all scales; mix the cut pieces with wet fine sand, put them in a plastic bag and seal and store in a dark place; after 1 month, small bulbs will be formed on each bulb cut piece , On each bulb cut, small bulbs are formed and expanded to 1.5-1.7cm, and after 1-6 roots are rooted, open the bag and refine the seedlings for 5-7 days, separate the grown small bulbs one by one, and transplant them in the open field.

Abstract

Disclosed is a diced breeding technique for Chinese narcissus which comprises, using one or two year-old narcissus bulb as raw material, cryogenic processing 4-8 weeks, cutting the bulb longitudinally into uniform small blocks in a radiation shape by using plateau as the center at normal temperature, with each block keeping the plateau and all the flakes, loading each cut small blocks of breeding material into poly bag containing washed and filtered dried sand, sealing the pocket opening, placing in dark places, shifting for culture in the open. The ball forming rate for cutting breeding and transplanting survival rate can be as high as 100%.

Description

Background technique: [0001] The invention relates to the cutting propagation technology of Chinese narcissus. [0002] The existing Chinese narcissus cutting propagation technology can be roughly divided into the following four kinds: [0003] 1. Side ball propagation: This is the most common method of daffodils propagation. The lateral bulbs are attached to both sides outside the bulb, and only the base is connected to the cue bulb, which can easily be separated from the parent body. Separate it from the cue ball in the fall and plant it alone to produce a new ball the following year. [0004] 2. Double-scale propagation: The bulb disc with 2 scales is used as the propagation material, which is called double-scale propagation. The method is: first put the bulbs at a low temperature of 4-10°C for 4-8 weeks, then cut the bulb discs into small pieces at room temperature, so that each piece has 2 scales, and cut off the upper end of the scales to leave 2cm as propagation mate...
