Problems solved by technology

[0006] There are many research reports on aerial bulb propagation technology, but the existing research has not formed a complete system. The garlic aerial bulb propagation technology generally has serious problems such as difficult germination, low germination activity, long cultivation time and low reproduction coefficient. It limits the large-scale application of garlic aerial bulb propagation technology, causing huge losses to scientific research and production
In order to solve the problems of difficult germination, low reproduction coefficient and long cultivation time in the existing garlic aerial bulb propagation technology, we invented a method for rapid and efficient germination of garlic aerial bulbs

Embodiment 1

[0046] The garlic varieties harvested in the current year are 'Cangshan Dahongpi' (early maturity), 'Sichuan Ershuizao' (medium early maturity), 'Sichuan Soft Leaf Garlic' (medium maturity), 'Majiang Red Garlic' (late maturity) Aerial bulbs were used as test materials. Choose healthy and plump aerial bulbs with typical characteristics of varieties, and divide them into three grades: large, medium and small according to the diameter of the aerial bulbs. Soak in 0.3% carbendazim and 0.3% potassium dihydrogen phosphate mixed solution for 12 hours, then soak in sterile distilled water for 12 hours, sow in vermiculite with water content of 60%, 20 grains per plate, repeat 5 times. The standard for germination is the length of the germ to the length of the aerial bulb. Count the number of germinated seeds every day, and calculate the five germination indicators of germination potential, germination rate, germination index, vitality index and average germination time. The calculatio...

Embodiment 2

[0058] Aerial bulbs of garlic varieties 'Cangshan Dahongpi', 'Sichuan Ershuizao', 'Sichuan Soft Leaf Garlic' and 'Majiang Red Garlic' harvested in the year, healthy and plump, of the same size and with typical traits were selected as test materials. , each kind of aerial bulb diameter size is the optimal diameter range that embodiment 1 screens. Aerial bulbs were soaked in a mixed solution of 0.3% carbendazim and 0.3% potassium dihydrogen phosphate for 12 hours, then soaked in sterile distilled water for 12 hours, and sowed in vermiculite with a water content of 60%, 20 grains per plate, 5 Repeatedly, randomly placed in the light incubator. Culture under 20 dark conditions, 20 light (12h, 10000Lux) culture as control. Take the length of the germ to the length of the aerial bulb as the germination standard, and the measurement index is the same as in Example 1.

Embodiment 3

[0063] The aerial bulb material (same as Example 2) was stored in 4 refrigerators, and the storage time was respectively 0, 7, 14, 21, and 28 days, and the aerial bulb germination test was carried out after storage. Soak in 0.3% carbendazim and 0.3% potassium dihydrogen phosphate mixed solution for 12 hours, then soak in sterile distilled water for 12 hours, sow in vermiculite with water content of 60%, 20 grains per plate, repeat 5 times, Randomly placed in the light incubator. Cultured at 20 dark conditions, 25 dark culture as a control. Take the length of the germ to the length of the aerial bulb as the germination standard, and the measurement index is the same as in Example 1.

Abstract

The invention discloses a method for quickly and efficiently germinating garlic aerial bulbs. The problems of low vigor, difficult germination, low propagation coefficient, long cultivation time and the like of the garlic aerial bulbs in a mode of combining pretreatment of the garlic aerial bulbs with strict regulation and control of a germination environment are effectively solved. The germination rate, the germination activity and the seedling growth vigor of the garlic aerial bulbs are remarkably improved, and the germination period is greatly shortened. The technology can be popularized and applied to garlic aerial bulb propagation on a large scale so as to accelerate garlic sexual recovery and complete garlic purification and rejuvenation, and then the growth vigor and stress resistance of garlic plants and the yield and quality of the garlic bulbs are improved.

Description

technical field [0001] The invention belongs to the technical field of garlic aerial bulb propagation, and in particular relates to a method for rapid and efficient germination of garlic aerial bulbs. Background technique [0002] Garlic (Allium sativum L.) is a biennial herb belonging to Amaryllidaceae (Amaryllidaceae), which has attracted widespread attention because of its unique flavor and high nutritional value. my country is the main garlic producing area in the world. In 2020, the garlic planting area in my country will exceed 800,000 hm 2 , accounts for 50% of the total global garlic planting area, its output accounts for 75% of the global total output, and its export volume is 2.232 million tons. It plays an important role in my country's vegetable export earnings. Due to the difficulty in flowering and fruiting of garlic, bulbs are usually used for asexual reproduction, and long-term asexual reproduction will lead to the accumulation of viruses and the degradation...
