Embodiment 1

[0017] A method for breaking the dormancy of delphinium grandiflora seeds, the method comprising the following steps:

[0018] (1) Seed collection: select robust plants without damage by diseases and insect pests, and when the seeds are fully mature, cut off the entire inflorescence with the seed bag with scissors and dry them in the sun, and screen out plump and fully mature seeds for later use;

[0019] (2) Soak the delphinium grandiflora seeds in a potassium dihydrogen phosphate solution with a temperature concentration of 50g / L for 12 hours, then soak them in 800 times thiophanate-methyl solution for 3 hours, and finally wash the seeds with warm water at about 25°C ;

[0020] (3) Preparation of plant extract: select well-developed plants, collect roots, stems, and leaves of vetiver, cut them into pieces with scissors after drying in the shade, weigh 2, 10, and 4 g of roots, stems, and leaves respectively, and add 100 times Distilled water, soaked at 25°C for 48 hours, fil...

Abstract

The invention discloses a method for interrupting dormancy of delphinium grandiflorum seeds. The method mainly comprises the steps of selecting seeds, soaking the selected seeds, soaking the seeds in plant extract liquor, and carrying out stratification treatment. The technologies, such as soaking and stratification treatment, are comprehensively used for interrupting the dormancy of the seeds, so that the germination time of the delphinium grandiflorum seeds is greatly shortened; furthermore, seedlings of the delphinium grandiflorum seeds obtained by the method are developed in root system, good in growth vigor, high in growing speed and high in survival rate.

Description

technical field [0001] The invention relates to a method for breaking the dormancy of delphinium grandiflorum seeds. Background technique [0002] Delphinium grandiflorum (Delphinium grandiflorum), also known as delphinium, delphinium, Ranunculaceae delphinium, perennial herb, wild species mainly produced in temperate regions of the northern hemisphere. The stem is erect, multi-branched, the plant height is 80-100cm, and the whole plant is pilose. Leaves alternate, palmately parted. Racemes terminal, sepals petal-shaped, blue, perennial herb, 35-65 cm high. Stems sparsely branched. Basal leaves and lower leaves of stems with long stalks; blades round, mold-shaped, 2.2-6 cm long, 4-8 cm wide, 3-lobed, lobes finely divided, small lobes strip-shaped, 0.6-2.5 mm wide. Raceme with 3-15 flowers, axis and pedicel with recurved puberulent; flowers left-right symmetrical; bracteoles strip-shaped or subulate; sepals 5, petal-shaped, blue or purple-blue, 1.5-1.8 long cm, with 1 sp...
