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] Harvest first- and second-year-old bulbs of narcissus from the field in early June, dry them in the shade, store them in bags, and place them at a low temperature of 4-10°C for one month; from late August to December each year, take out the bulbs that have been treated at low temperature, and store them as bulbs at room temperature. The center of the plate is a dot, and the bulbs are cut into uniform small pieces radially, each piece has a bulb plate and all scales; mix the cut pieces with wet fine sand, put them in a plastic bag and seal them, and store in a dark place; 1 After one month, small bulbs are formed on each bulb cut block, and the small bulbs that have grown are separated one by one, and then transplanted to the open field.

Embodiment 2

[0021] Harvest first- and second-year-old bulbs of narcissus from the field in early June, dry them in the shade, store them in bags, and place them at a low temperature of 4-10°C for one month; from late August to December each year, take out the bulbs that have been treated at low temperature, and store them as bulbs at room temperature. The center of the disc is a dot, and the bulbs are cut into uniform small pieces radially, each piece retains the disc with the bulb and all the scales; the cut bulbs must be cut into pieces and ventilated for several hours, then mixed with washed wet fine sand, Store in a dark place after being sealed in a plastic bag, and open the bag to ventilate once every 15 days; after one month, small bulbs will be formed on each bulb cut, and the small bulbs that have grown will be separated one by one and transplanted in the open field.

Embodiment 3

[0023] Harvest first- and second-year-old bulbs of narcissus from the field in early June, put them in bags and place them at a low temperature of 4-10°C for one month; take out the bulbs that have been treated at low temperature, and cut the bulbs longitudinally radially at room temperature with the center of the bulb disc as a dot. Uniform small pieces, keep the bulb plate and all scales for each piece; mix the cut pieces with wet fine sand, put them in plastic bags and seal them, and store them in a dark place; after 1 month, small bulbs will be formed on each bulb cut piece , generate small bulbs on each bulb cut and expand to 1.5-1.7cm, and after rooting 1-6, open the bag and harden 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

technical field [0001] The invention relates to the technique of cutting and propagating Chinese narcissus. Background technique [0002] The cutting propagation techniques of existing Chinese narcissus can be roughly divided into the following four types: [0003] 1. Side ball propagation: This is the most commonly used method for narcissus propagation. The lateral balls are born on both sides outside the bulb, and only the base is connected with the cue ball, so it is easy to break away from the mother body. In autumn, it is separated from the cue ball and planted separately, and new balls will be produced the following year. [0004] 2. Double-scale propagation: Use a bulb disc with 2 scales as the propagation material, which is called double-scale propagation. The method is: first place the bulbs at a low temperature of 4-10°C for 4-8 weeks, then cut the bulbs into small discs at room temperature, so that each piece has 2 scales, and cut off the upper end of the scale...
