Problems solved by technology

At present, most of the research on the scale cutting technology of Liliaceae plants is concentrated on Lilium plants, but the current cutting technology of Lilium plants usually has many problems such as scale rot, low rooting survival rate, low reproduction coefficient, and greater influence by seasonal factors. It can not achieve the ideal effect, and it is not suitable for large-scale promotion and use, and the research on the cutting technology of Dalilia scale has not been reported yet.

Embodiment 1

[0032] (1) Bulb pre-cultivation: On September 8, 2016, collect 2-year-old Dali bulbs with a diameter ≥ 10 cm, prepare peat soil and put them into plastic baskets with a length × width × height of 45 cm × 35 cm × 25 cm As the pre-culture medium, the pre-culture medium was drenched with 0.5% potassium permanganate solution for 2 times, and then drenched with clear water, and the collected bulbs were buried in the pre-culture medium, and the bulbs were embedded The depth of the pre-cultivation medium is 5 / 6 of the bulbs, and there is a gap of 10 cm between the bulbs. The bulbs are placed in an air-conditioned room with a constant temperature of 20 °C for pre-cultivation of the bulbs, and water is poured every 3 days. Do not spray too much water to prevent the bulbs from rotting. Spray the surface of the bulbs and the pre-culture substrate with 50% carbendazim wettable powder 500 times every 7 days to disinfect the bulbs and the pre-culture substrate.

Abstract

Provided is an efficient cuttage and propagation method for cardiocrinum giganteum bulb scales. The method includes the steps of preculture of seed balls, sterilization of the bulb scales, processing of the bulb scales, preparation of cuttage substrates, cuttage of the bulb scales and management after the cuttage. According to the method, the bulb scales after sterilization are adopted for cuttage and propagation, the method is easy to implement, the conditions are easy to control, the characters of the female parents are maintained, and meanwhile bulb degeneration and virus accumulation are prevented; before the cuttage of the bulb scales, the preculture of the seed balls is conducted at 20 DEG C to decrease viruses carried by the seed balls, and the cuttage is not limited by seasons; during processing of the bulb scales, by conducting lengthwise cutting on the bulb scales, the propagation coefficient, compared with a normal bulb scale cuttage, is increased greatly and can be increased to over 4.0 times, and when compare with small bulb propagation, the propagation coefficient is increased by over ten times; three days after the cuttage of the bulb scales, a 250 mg / L ABT 2# solution is sprayed into the substrates to promote fast rooting of the bulb scales; around 10 days later, roots germinate, and the rooting rate reaches 98% or above; around 30 days later, seed balls are formed; by adopting the method, a great number of ardiocrinum giganteum seed balls which are healthy and free of diseases and viruses can be obtained in a short time, and therefore the method is suitable for large-scale propagation of cardiocrinum giganteum, and has a wide market application prospect.

Description

technical field [0001] The invention belongs to the technical field of cutting asexual propagation of plants, and in particular relates to a method for efficient cutting propagation of large lily scales. Background technique [0002] Lily ( Cardiocrinum giganteum ), also known as heart leaf lily and water lily, is an extremely cold-resistant plant of the genus Cardiocrinum in the family Liliaceae. , the flowers are white and fragrant, and it has the reputation of Prince Lily, which is widely distributed in our country. In recent years, through introduction, domestication and artificial cultivation, Dalily has become an excellent ornamental plant. In addition, its bulbs are rich in starch and more than 10 kinds of nutrients, which can be eaten. At the same time, Da Lily also has high medicinal value. It can not only nourish the middle and replenish Qi, clear the heart and calm the nerves, broaden the chest and benefit the Qi, moisturize the lungs, relieve cough, and detoxi...
