Problems solved by technology

[0004] After many years of field research, introduction and domestication, biological observation, and breeding experiments, it was found that although the group flowering period of this species is long, the flowering volume is small and the flowering uniformity is not high; less, difficult to harvest
The way to obtain a large number of plants through seed propagation is very limited, and the method of branch clone propagation is the only efficient way to obtain a large number of plants in a short period of time; however, there is no related report

Embodiment 1

[0029] A method for asexual propagation of Ziyun vetch, comprising mother plant cultivation, mother plant cultivation, strip source cutting treatment, root-inducing treatment, intensive cultivation and independent cultivation, and the specific steps are as follows.

[0030] (1) Mother plant culture

[0031] Select a plot with medium fertility and a certain slope, prepare the site, remove weeds and apply 50g / m 2 Sprinkle calcium-magnesium-phosphorus fertilizer as the base fertilizer; and take the purple cloud vegetable and cut the pile to 8-10cm short, trim off the excessive long fibrous roots, and then plant with an appropriate row spacing, planting at a row spacing of 60cm×60cm. The planting depth is equal to the root neck, and the root-fixing water is poured once after planting. During the slow seedling period, water should be replenished in time depending on the weather and soil humidity, and the plants will survive in about 1 week.

Abstract

The invention discloses a Strobilanthes vegetative propagation method comprising steps of parent plant culture, branch source culture, branch source cutting processing, bacteriostatic agent processing after stem section cut, and root inducing processing as well as intensive culture and independent culture. In the branch source culture step, additional fertilizer is applied when new buds of parent plants grow to 3 to 4cm; internodes of branches with nodes or partially with nodes surrounding parent plant cluster are peeled and cut; 600mg / L of carbendazol solution is sprayed on cut wounds; then 30mg / L indolebutyric acid is employed for processing internodes; nodes of the plants are longitudinally cut, so the base part of each side branch is provided with a part of node to form a stem section; after the bacteriostatic agent processing after stem section cut step, the stem section is reversed; in the root inducing processing step, growth hormone solution is sprayed on the lower end of the stem section to the surface of the stem section for humidifying; then the stem section is placed right; atomizing water is sprayed to the lower end of the stem section. Strobilanthes vegetative propagation can be achieved; a problem that Strobilanthes plants cannot be acquired on a large scale by the use of seed propagation in the prior art can be solved; an air culture mode is employed, so corrosion due to water culture and soil culture can be avoided and possibilities of bacterial infection and spreading can be reduced.

Description

technical field [0001] The invention relates to a method for plant propagation and cultivation, in particular to a method for asexual propagation of Ziyuncai. Background technique [0002] Purple cloud dish, Latin name Strobilanthesoliganthus Miq. [Championella oligantha (Miq.) Bremek. Less flowered horse blue, perennial herb. The basal node is enlarged and geniculate, the stem is sparsely branched, has obtuse edges, and has white multicellular long hairs. The leaves are opposite; the stalk is 1-5cm long, with wings on the upper part of the stalk. [0003] Strobilanthes limprichtii Diels is a herb or subshrub of the genus Strobilanthes limprichtii Diels in the family Acanthaceae. Only a small amount of wild resources are distributed on the rocky slopes of streams at an altitude of about 1,200 meters in Litang, Ya'an, Sichuan, and Deqin, Yunnan, which have a certain degree of drought tolerance. The plant height of Ziyuncai is 20-30cm, the natural pruning power is strong, a...
