Embodiment 1

[0022] 1) set up a width of 100cm on the selected breeding ground, a seedbed with a length of 250cm, build a shed on the seedbed, cover the plastic film on the shed, and add a shade net; laying a cutting substrate with a thickness of 10cm on the seedbed, wherein the substrate The mass ratio is: garden soil: humus soil: perlite=1: 1: 1; the seedbed and the matrix on it are thoroughly disinfected with 5% potassium permanganate solution diluted 1000 times with a mass concentration, and the Cuttings can be carried out;

[0023] 2) After harvesting the stolons from the Diannian Sea Hydrangea plant in October, cut the fringe, that is, cut it into cuttings with 1 / 3 leaves and a stem length of 6 cm, and use a flat incision, and the incision is smooth; the resulting cuttings are cut into the above-mentioned In the substrate, the cutting depth is controlled to be 4cm, and the cutting density should be such that the leaves do not overlap after cutting; after cutting, water the substrate ...

Embodiment 2

[0030] 1) set up a width of 100cm on the selected breeding ground, a seedbed with a length of 300cm, build a shed on the seedbed, cover the plastic film on the shed, and add a shade net; laying a cutting substrate with a thickness of 8cm on the seedbed, wherein the substrate The mass ratio is: garden soil: humus soil: perlite=1: 2: 2; the seedbed and the matrix on it are thoroughly disinfected with 5% potassium permanganate solution diluted 1000 times, and carried out after 24 hours. cuttings;

[0031] 2) After picking the stolons from the Dianhai sea nymph plant in November, cut the fringe, that is, cut it into cuttings with 1 / 3 leaves and a stem length of 5 cm, and use a flat incision, and the incision is smooth; the resulting cuttings are cut on the above-mentioned In the substrate, control the cutting depth to 3 cm, and the cutting density should be such that the leaves do not overlap after cutting; after cutting, water the substrate thoroughly, cover the shed with plastic...

Abstract

The invention provides a method for cutting and propagating creeping stems of primula pseudodenticulata pax view. The method comprises the following steps of: cutting the creeping stems picked from the primula pseudodenticulata pax view plant into 1 / 3 leaves, cutting the young seedlings with the stem length of 5 to 6cm into the matrix with the thickness of 8 to 10cm and the following mass ratio: garden soil: humus soil: perlite is equal to 1:1 to 2:1 to 2, the cutting depth is controlled to 3 to 4cm, the cutting density is better to non-overlap the leaves of the cutting young seedlings, the matrix is watered thoroughly after cottage, plastic films and sunshade screens are used for covering, management after cottage is carried out according to the conventional manner, and the hardening offof the seedlings can be carried out after 20 to 25 days. The method not only has easy seedling cutting and large amount, but also has easy cuttage, fast propagating speed, obtains strong hardened-offseedlings with strong insect prevention and disease resistance, has the survival rate of 60 to 70 percent after transplantation, is beneficial to industrial development of the primula pseudodenticulata pax view and has wide market prospect.

Description

technical field [0001] The invention relates to a method for cutting and propagating stolons of Dianhai sea nymphs, belonging to the technical field of plant cultivation. Background technique [0002] Primula pseudodenticulata Pax is a perennial herb of Primulaceae Primulaceae, and the whole plant is glabrous. The rhizome is very short, and stolons can grow from the top. Many leaves, oblanceolate to narrow obovate oblong, 3-10cm long, 0.5-2.5cm wide, scape 6-35cm high, umbels subcapitate, many flowers, corolla pink to lavender blue , the flowering period is from December to February of the following year, and the fruiting period is from March to April. Dianhaixianhua likes well-drained soil; likes light, has a certain shade tolerance; likes humid environment. The root system of Dianhaixianhua is well developed, the growth is strong, and the adaptability to the environment is strong. In addition to the daily fertilizer and water management, no other management measures are...
