Asexual propagation method of lily bulb

The main results are as follows: (1) Natural reproduction of small bulbs: naturally divide the female bulb into a single bulb (2mur5 bulbs, each containing a growing point), plant in the field for one year, and then grow into a larger new bulb, and then plant and reproduce, so repeatedly you can get a standard bulb. The disadvantage of this method is that the number increases slowly, the amount of seed used is large, the disease and variety degradation are serious, and the breeding time is shortened, and the seed ball can be obtained in 1-2 years.

(2) bulb (bulb) reproduction method: small bulbs are planted in the field, and larger bulbs can be formed after several years of cultivation. The reproduction coefficient of this method is larger (for example, a musk lily has dozens of bulbs), and the plant is robust after emergence, but the cultivation time is longer than that of bulb reproduction.

(3) scale propagation method: ① selects strong and disease-free plants and collects bulbs when the leaves begin to turn yellow (it is suitable for larger individuals). ② carefully peeled off the robust scales one by one and soaked them in 1 lug 500 carbendazim or carbendan solution for 30 minutes. Dry cuttings were put into the matrix 1 to 2mer 2 to 3 (the same as before) and placed in the shade after spraying water. ③ cuttings in September, and several bulbs can be formed on each scale in November. ④ the following spring, the small bulbs took root, produced leaves, and formed larger bulb new individuals. After several years of continuous cultivation, the seed ball was obtained.

(4) Propagation of bulbs: purple-black buds can grow in the axils of stem nodes and leaves of some varieties, such as lilies and yellowish lilies. The bulb is composed of several thick scales, which can naturally take root and grow leaves in the soil and form small plants. its effect is roughly the same as the reproduction of bulbs and bulbs.

(5) Cuttage propagation of stem and leaf: stem propagation is a new method of reproducing bulbs, which is carried out by making use of the characteristics that lily branches can survive after cutting, form new plants and regenerate bulbs. Select the sterile twigs that grew in the same year (preferably close to the ground), cut into 10ml 13cm segments, soak the base 4ml 5cm in 0.01% indole acetic acid or 0.005% naphthalene acetic acid water for 10 minutes, and cut into the nutrition bowl of the seedling bed. The seedbed should be leeward, sunny, warm, well drained and made of sand. The cultivated soil in the nutrition bowl is composed of four parts of pastoral soil, four parts of fully ripened fine compost and two parts of river sand. After planting, we should pay attention to shading, watering, keep the soil moist, the temperature 20-30 ℃, 8 days can produce callus, 20 days later can take root, the rooting rate can reach more than 96%. It can be transferred to the field for cultivation after 30 days. The experimental results show that a cuttage can produce 7 bulbs with a diameter of 2mm and 5cm, some of which can reach more than 10, and the harvested bulbs can be used for field cultivation. In addition, small bulbs can also be obtained by operating the upper leaves of lilies according to the above method, but this method is generally not used.
