Problems solved by technology

However, the above-mentioned methods of asexual reproduction of bulbous flowers all destroy the growth of the cue ball, affecting the flowering of the cue ball this season, and the diameter and quality of the separated child balls are all small, and the period required to become a flowering bulb is longer

Embodiment 1

[0025] The present embodiment relates to a method for digging and propagating narcissus bulbs, said method comprising the steps of:

[0026] Step 1. Use the narcissus variety N.pseudonarcissus 'Shangnongdieying' as the test material. On August 5, 2012, select a 3-year-old, 12-14cm circumference, high maturity, no pests and diseases, and a complete base plate. For bulbs, use a sharp spoon or a spoon knife to hollow out the base of the bulb to a depth of about 1.5cm, leaving the edge of the bulb intact;

[0027] Step 2, after soaking with 600 times carbendazim for 5 minutes, remove and dry in the shade;

[0028] Step 3, spread the treated bulbs in a matrix mixed with plant ash: river sand in a volume ratio of 5:2, store and place in a dark environment with a temperature of 20°C and a humidity of 30%; callus will form after 6-8 days , during the bulb storage process, spray water into the matrix at intervals to increase the humidity and prevent the bulb from dehydrating and dryin...

Embodiment 2

[0032] The present embodiment relates to a method for digging and propagating narcissus bulbs, said method comprising the steps of:

[0033] Step 1, using the narcissus variety Shangnongzaochun (N.pseudonarcissus 'Shangnongzaochun') as the test material, on August 5, 2012, select 5-year-old bulbs with a circumference of 14cm, high maturity, no damage by diseases and insect pests, and complete bulbs with a base plate; Use a spoon or a spoon-shaped knife to hollow out the base of the bulb to a depth of about 1.2cm, leaving the edge of the bulb intact;

[0034] Step 2, after soaking with 700 times carbendazim for 8 minutes, remove and dry in the shade;

[0035] Step 3, spread the treated bulbs in the substrate mixed with plant ash: river sand in a volume ratio of 8:3, store and place in a dark environment with a temperature of 20°C and a humidity of 30%; callus will form after 6-8 days , during the bulb storage process, spray water into the matrix at intervals to increase the hu...

Embodiment 3

[0039] The present embodiment relates to a method for digging and propagating narcissus bulbs, said method comprising the steps of:

[0040] Step 1, using the narcissus variety Shangnonghongying (N.pseudonarcissus 'Shangnonghongying') as a test material, on August 5, 2012, select 5-year-old bulbs with a circumference of 13 cm, high maturity, no pests and diseases, and a complete base;

[0041] Step 2. Use a sharp spoon or a spoon-shaped knife to hollow out the base of the bulb to a depth of about 1.5 cm, and keep the edge of the bulb disc intact; soak it in 700 times carbendazim for 10 minutes, remove it and dry it in the shade;

[0042] Step 3, spread the treated bulbs in a matrix mixed with plant ash: river sand at a volume ratio of 10:5, store and place in a dark environment with a temperature of 20°C and a humidity of 30%; callus will form after 6-8 days , during the bulb storage process, spray water into the matrix at intervals to increase the humidity and prevent the bul...

Abstract

The invention provides a method for hole digging breeding of a narcissus bulb. The method comprises the steps of 1, taking the narcissus bulb, hollowing a base of the narcissus bulb, and keeping the edge of the base of the narcissus bulb intact; 2, conducting treatment with a bactericide; 3, spreading the narcissus bulb in a matrix, and storing the narcissus bulb in a warm, dry and dark environment to form a callus; 4, conducting cold storage in a dry and dark warehouse till planting. The hole digging breeding technique is simple, easy to implement, safe and efficient, narcissus bulb propagation coefficient is increased, and current-season growth of a mother bulb is not affected; furthermore, nutrient absorption and growth of newly born small bulbs are facilitated during planting, and then time for blooming of the narcissus bulb is shortened.

Description

technical field [0001] The invention relates to the field of flower propagation methods; in particular, a method for digging holes for narcissus bulbs. Background technique [0002] Narcissus (Narcissus pseudonarcissus L.) is a perennial ornamental herb of the genus Narcissus in the family Amaryllidaceae. It has bright colors and unique flower shapes and is widely used in landscaping. The propagation methods of narcissus mainly include seed propagation, ball propagation and tissue culture. The period required for seed propagation is long, and it is easy to produce buds; under natural conditions, the bulbs produced by sphere propagation are small, the number is small, and they are susceptible to diseases; tissue culture is more efficient, but the operation is complicated, the technical content is high, and the cost is high. Therefore, it is very important to seek simple, efficient and fast breeding methods. [0003] So far, the bulb propagation technology of various bulbous...
