Description

Technical Field

[0001] This invention relates to the field of garden plant cultivation and maintenance, and in particular to a method for the live propagation of lily bulbs. Background Technology

[0002] As one of the world's most famous bulbous flowers and one of the five major cut flowers, the lily possesses multiple values—medicinal, ornamental, and edible—giving it a very broad development prospect in the flower industry. The development of the lily industry and the continuous expansion of market demand have placed higher demands on the quality and quantity of lily bulbs. my country's lily seed industry is basically in its infancy.

[0003] Bulbils are a form of reproduction in lilies, consisting of above-ground organs that grow within axillary buds and originate from axillary meristems, similar to tillers in Arabidopsis thaliana and rice. Bulbils and bulbs are essentially the same reproductive organs of lilies, but they differ in their location. Bulbs grow underground, while bulbils grow above ground. After maturing, the bulbils fall to the ground and begin to develop into bulbs. However, not all lily species can form bulbils. Currently, four wild lily species—L. lancifolium, L. sulphureum, L. sargentiae, and L. bulbiferum—are known to naturally form bulbils at the axillary buds of their stems. However, this method of reproduction is only applicable to certain lily species where bulbil formation is present.

[0004] Obtaining bulbs through scale cuttings is currently the main method of lily propagation, but the price of lily bulbs has remained high and is increasing year by year, causing the cost of propagation to rise daily. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a method for the live propagation of lily bulbs that is low in cost, easy to operate, and has excellent results.

[0006] The method for propagating lily bulbs from live organisms according to the present invention includes the following steps:

[0007] After 3-4 weeks of germination, spray the seedlings with an amino acid water-soluble fertilizer containing chlorpyrifos or thiamethoxam. Two months after the lilies bloom, the bulbils growing from the plant stems will mature. Cut the plant stems from the base, cut them into small sections according to the planting container, bury them in nutrient soil, and water them for cultivation.

[0008] The method for propagating lily bulbs by live organisms according to the present invention, wherein the dilution ratio of the amino acid water-soluble fertilizer is 1:1000, and after dilution, chlorpyrifos or thiamethoxam is added, wherein the volume ratio of chlorpyrifos to the diluted amino acid water-soluble fertilizer is 1:50, and the volume ratio of thiamethoxam to the diluted amino acid water-soluble fertilizer is 1:50.

[0009] The method for propagating lily bulbs by live organisms according to the present invention, wherein the circumference of the lily bulbs is 6-8 cm, they are cultivated in a greenhouse, with normal watering management, and sprayed 3-4 weeks after germination, wherein the spraying is foliar spraying.

[0010] The method for propagating lily bulblets by live organisms according to the present invention involves spraying once more after a three-week interval, and then spraying again two months after the lily blooms, when the bulbils growing from the plant stems mature.

[0011] The method for propagating lily bulblets by live organisms according to the present invention involves cutting the plant stem from the root after the bulbils mature. When planting, the stem with bulbils is cut into 7-10cm segments and placed horizontally in nutrient soil. The segments are covered with 2-3cm of nutrient soil and watered with water containing rooting powder to promote root growth. After 2 weeks, the bulbils develop roots, and after 1 month, they can grow scale leaves. After 1-2 years of planting, they grow into lily bulblets.

[0012] The method for propagating lily bulbs using live organisms in this invention differs from existing technologies in that:

[0013] This invention provides a method for the live propagation of lily bulbs that breaks with traditional methods and takes a different approach. By using exogenous regulation to induce bulbils in the plant stems for the production of lily bulbs, the propagation cost of lily bulbs is significantly reduced, which will greatly promote the development of my country's lily seed industry.

[0014] The method of this invention can harvest bulbils and seed bulbs. The size and weight of the seed bulbs are no different from the control, indicating that the nutrients and energy consumed by bulbil growth can be compensated by the use of amino acid water-soluble fertilizer. This shows that the method of this invention can obtain bulbils for lily propagation without affecting the original yield of lilies.

[0015] The method for propagating lily bulbs using live organisms according to the present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0021] 1. Experimental Materials

[0022] Lily bulbs, amino acid water-soluble fertilizer, chlorpyrifos, thiamethoxam, and "Ruqing" brand substrate nutrient soil.

[0023] 2. Experimental Methods

[0024] Plant the small bulbs of 'Shuttle' lily (6-8cm in circumference) in nutrient soil, cultivate them in a greenhouse, and manage and water them normally. 3-4 weeks after germination... Figure 1 Foliar spraying with an amino acid water-soluble fertilizer containing chlorpyrifos or thiamethoxam (ensuring complete coverage of the entire plant) is recommended. The amino acid water-soluble fertilizer should be diluted 1:1000 by volume. After dilution, add chlorpyrifos or thiamethoxam at a ratio of 1:50 for both. Repeat the spraying after 3 weeks. Two to three months after flowering, when the bulbils on the stems mature and can root normally, cut the stems from the base into 7-10cm segments, depending on the planting container. Place these segments horizontally in the potting soil and cover with 3-4cm of potting soil. Water with water containing rooting powder to promote rooting and sprouting of the bulbils.

[0025] 3. Experimental Results

[0026] 3.1 Effects of amino acid water-soluble fertilizer, chlorpyrifos, and thiamethoxam on the growth of lily bulbils

[0027] Three weeks after the lily bulbs sprout, foliar spraying was applied using fertilizers #1 (amino acid water-soluble fertilizer), #2 (amino acid water-soluble fertilizer + chlorpyrifos), and #3 (amino acid water-soluble fertilizer + thiamethoxam). Treatments #2 and #3, which contain chlorpyrifos and thiamethoxam, resulted in bulbils beginning to sprout from the leaf axils of the stems after 3-4 weeks. Figure 2 The growth of bulbils will delay flowering by about one week. Bulb harvest statistics are shown in the table below. Figure 3The results showed that treatment #1 significantly increased bulb yield, with a marked increase in both bulb size and circumference. Treatments #2 and #3 both yielded bulbils and stem bulbs, with no difference in bulb size and weight compared to the control. This indicates that the nutrients and energy consumed by bulbil growth can be compensated for by the use of amino acid water-soluble fertilizer. Therefore, this method can obtain bulbils for lily propagation without affecting the original lily yield.
