Description

Technical Field

[0001] This invention relates to the field of plant propagation technology, specifically to a method for propagating Lanzhou lily by scale cuttings. Background Technology

[0002] Lanzhou lily, a unique edible sweet lily variety in China, has a cultivation history of over 400 years. It is mainly distributed in Qilihe District of Lanzhou City and surrounding areas in Gansu Province. For a long time, Lanzhou lily has relied mainly on small bulbs at the base of the stem for asexual reproduction, which has led to variety degeneration and virus accumulation, seriously affecting yield and quality. At the same time, traditional cultivation requires 3 years to cultivate seed bulbs and 3 years to grow commercial bulbs, which is inefficient and cannot meet market demand. Furthermore, farmers' self-retained seed bulbs have led to a high incidence of viral diseases such as lily yellowing disease and root rot, which seriously affect the commercial yield.

[0003] With the advancement of modern plant biology, cutting propagation technology has gradually been introduced into the propagation process of Lanzhou lilies. As a method of asexual reproduction, cuttings can rapidly form new individuals by directly inserting healthy plant branches or scales, thus achieving rapid proliferation. However, scales are neither tolerant of waterlogging nor drought; excessive soil moisture can easily lead to rot, while insufficient moisture can affect rooting. Existing artificial watering methods are difficult to control precisely, easily causing scale damage and disease. At the same time, untreated bulbs may carry cucumber mosaic virus and lily asymptomatic virus, affecting the survival rate and bulb quality after scale cutting. Furthermore, existing cutting methods still have the disadvantages of insufficient propagation efficiency and unsatisfactory growth results.

[0004] To address the above problems, the present invention provides a solution. Summary of the Invention

[0005] The purpose of this invention is to provide a method for propagating Lanzhou lily by scale cuttings, which has the advantages of high propagation efficiency, good growth effect and low disease incidence.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A method for propagating Lanzhou lily by scale cuttings includes the following steps:

[0007] S1: Select loam soil with a slope of less than 15°, sufficient sunlight, loose and fertile soil, good drainage, and a pH value of 6.2-7.5, and whose previous crop was not a lily family crop. After rotary tilling, deeply plow to 30-40cm and expose to the sun for 15-20 days to prevent water accumulation and soil compaction. In March, after the ground has completely thawed, use 40 bags of fully decomposed and fermented sheep manure per acre (40kg per bag), 1 bag of Trichoderma harzianum (1kg per bag), 1 bag of Bacillus subtilis (1kg per bag), 4 bags of compound microbial fertilizer (40kg per bag), and 5 kg of trace element organic chelated fertilizer, including 1 kg each of iron, zinc, calcium, magnesium, and manganese. Spread the fertilizer evenly, rotary till it into the soil, grind it flat, and set it aside. At the same time, mix in soil disinfectant for soil disinfection. The application rate of soil disinfectant is 5kg / acre.

[0008] S2: After disinfection, prepare the land and make ridges with a ridge width of 90cm and a ridge height of 10cm. Cover the ridges with 0.015-0.02mm white mulch film and lay drip irrigation tape with a dripper flow rate of 2L / h under the film with a spacing of 40cm.

[0009] S3: Select lilies harvested in spring, choosing those with single heads or tightly wrapped ends, large petals, regular shape, no damage, pests, or rot, and healthy and of high quality as mother plants. Remove individuals with mechanical damage, mold, or necrotic buds and place them in a 10℃ environment for 48 hours, then transfer them to a 15℃ environment to air dry for 24 hours. After air drying, soak them in disinfectant solution for 30-40 minutes, turning them twice during disinfection to ensure full contact.

[0010] S4: After soaking, place the scales in a room temperature environment with 60% humidity for 6-8 hours to air dry. Observe that a translucent callus membrane forms at the base of the scales. Then peel off the outer dry scales and select the third to fifth thick scales with 5% basal tissue. Spray the rooting powder solution onto the base of the scales to moisten them. Then place them in a dark box at 25℃ and 85% humidity for 24 hours to induce rooting.

[0011] S5: Make horizontal furrows on the ridge surface, with a depth of 8cm and a row spacing of 7-8cm. Spread a 0.5cm thick layer of wheat straw at the bottom of the furrow and apply pest control agent at a rate of 5kg / mu. Then, plant the scales at a 3.5-4cm spacing, with the scales at a 75° angle to the ground, concave side facing up, and the top exposed 1cm above the soil. After planting, gently press the surrounding soil to ensure close contact. Immediately drip irrigate for 5 minutes at a rate of 3m³ / mu.

[0012] S6: After drip irrigation, spray 5% Trichoderma solution on the wheat straw until the surface is moist, then cover it on the ridge with a thickness of 2cm, then cover it with 30g / ㎡ non-woven fabric, and finally cover it with 0.015-0.02mm white mulch film. In early spring when the temperature is low, set up PE greenhouse film, uncover it during the day and cover it at night.

[0013] S7: During the rooting period, maintain air humidity at 70-80% and soil temperature at 18-22℃. When the soil temperature exceeds 25℃, remove the mulch for ventilation. Seven days after oblique planting, drip irrigate with integrated microbial fertilizer at a rate of 3m³ / mu, and foliar spray with 2×10 at a rate of 10kg / mu. 9 CFU / g Trichoderma harzianum granules, foliar spray with integrated organic fertilizer weekly during the seedling stage, spraying amount 30-50L;

[0014] S8: After the above-ground parts have withered and turned yellow, dig them up on a non-rainy day 15 days later. Select single independent lily bulbs weighing 30g or more as finished bulbs, and single independent lily bulbs weighing 20-29g as the next cutting bulbs. Single independent lily bulbs weighing 10-19g are re-propagated and cultivated for another year. Single independent lily bulbs weighing less than 10g are discarded.

[0015] Furthermore, the soil disinfectant mentioned in step S1 is 1.25 g / L of 50% thiram wettable powder and 0.5 ml / L of 5% abamectin emulsifiable concentrate; the disinfectant mentioned in step S3 is 0.6 g / L of 50% carbendazim soluble powder, 0.5 g / L of 3% kasugamycin soluble powder, 0.2 g / L of 25% thiamethoxam water-dispersible granules, 0.2 ml / L of 25% pyraclostrobin emulsifiable concentrate, and 0. The solution consists of 25 ml / L of 0.01% brassinolide soluble concentrate and 0.05 g / L of sodium nitrophenolate; the rooting powder solution mentioned in step S4 is 2 g / L of ABT1 rooting powder and 0.05 g / L of naphthaleneacetic acid; the pest control agent mentioned in step S5 is 3 kg / mu of 5% phoxim granules and 0.5 g / L of 10% imidacloprid soluble powder; the integrated microbial fertilizer mentioned in step S7 is 5% alginic acid diluted solution and 10 8 Bacillus subtilis CFU / ml; the integrated organic fertilizer mentioned in step S7 is 0.2wt% potassium dihydrogen phosphate and 0.1wt% chelated iron.

[0016] In summary, due to the adoption of the above technical solutions, the beneficial effects of this invention are as follows: This method can effectively reduce virus transmission, lower the risk of soil-borne diseases, and improve the qualified rate of commercial bulbs through double disinfection combined with Trichoderma biological control; at the same time, the hormone-optimized single-scale treatment combined with film-covered drip irrigation technology can greatly shorten the cultivation cycle of commercial bulbs; and the double film covering combined with precise water and fertilizer management can effectively reduce irrigation costs, improve fertilizer utilization, and significantly increase yield per acre and the optimized rate of commercial bulbs. It achieves a comprehensive breakthrough in efficiency, cost, and quality, and is suitable for the needs of large-scale planting and industrial upgrading. Detailed Implementation
