Embodiment 1

[0025] (1) Collected wild berries of Jade Leaf Golden Flower in mid-November, 2012, and stored in a cool place indoors, the balls will become soft after 3-4 days.

[0026] (2) In the middle and late November of 2012, put the softened berries in a basin with clean water and rub them repeatedly to fully separate the seeds from the pulp, and wash the pulp on the surface of the seeds. Remove impurities such as floating fruit chips, remove the sinking seeds and impurities, drain them, and dry them in a cool place. Use a 30-mesh fine sieve to screen out the mixture of seeds and fruit chips, and then use a 55-mesh fine sieve to remove fruit chips and impurities to obtain net Kinds, packed in kraft paper bags and stored in a dry and cool place.

[0027] (3) At the beginning of May 2013, sieve the forest humus soil as the substrate, spray and stir with clean water until the substrate is fully wet, hold it into a ball, but it is suitable to pat it loose. Use a white plastic pot with a ...

Embodiment 2

[0035] (1) In mid-November 2015, collect and cultivate the special-shaped Jade Leaf Golden Flower fruits in the nursery, store them in a cool place indoors, and the balls will become soft after 3-4 days;

[0036] (2) Put the softened berries in a pot and rub them with water to fully separate the seeds from the pulp. Remove the floating pulp and other dregs, drain the seeds and berry fines with a cloth, dry them in a cool place, sieve the seeds with a 30-mesh fine sieve, and then use a 55-mesh fine sieve to remove fine impurities such as pulp, and use Store net seeds in paper bags in a dry and cool place.

[0037](3) In mid-April 2016, sieve the forest humus soil as the substrate, spray and stir the fine soil with clean water until it is fully moist, and form a ball with your hands, but it is suitable to pat it loose. Use a 40 cm diameter and 15 cm deep white plastic pot to make the seeding pot. There are 4 drainage holes with a diameter of about 0.5 cm in the bottom of the po...

example 3

[0045] (1) In late November 2017, we collected and cultivated the special-shaped Yuye Jinhua berries in the nursery and stored them in a cool place indoors. After 4-5 days, the balls became soft;

[0046] (2) In late November 2017, put the softened berries in a pot with clean water and rub them repeatedly to fully separate the seeds from the pulp. Remove the floating fruit chips and other dregs, remove the sinking seeds and fine berry particles, drain them, and dry them in a cool place. Use a 30-mesh fine sieve to screen out the seed-fruit chip mixture, and then use a 55-mesh fine sieve to remove the fruit chip impurities. Obtain the net seeds of the heteromorphic jade leaf golden flower, pack them in kraft paper bags and store them at room temperature.

[0047] (3) At the beginning of May 2018, the forest humus soil was sieved as the substrate. The fresh natural humus soil had moderate moisture, and it was formed into a ball by hand, but it would disperse when patted lightly....

Abstract

The invention discloses a seed breeding method of endangered rare plant Mussaenda anomala. The method includes the steps of firstly, collecting fruits, and placing in a shady place for 3-5 days to soften the fruits; secondly, screening out pure seeds, and packaging with paper bags for storage; thirdly, using sieved forest humus soil as the substrate to produce sowing pots in next spring; fourthly,soaking the seeds for 8-10 hours, sowing the seeds according to 6-8g / m<2>, sufficiently watering in a spraying manner, and keeping appropriate temperature, humidity and illumination; fifthly, using forest humus soil as the substrate to produce transplanting pots; sixthly, transplanting according to the plant distance of 4-5cm after the cotyledons of the seedlings grow, and keeping appropriate temperature, humidity and illumination; seventhly, gradually uncover films to exercise the seedlings after the seedlings grow 3-4 pairs of cotyledons, and the removing the films after 4-5 days; eighthly,transplanting into a field when the height of the seedlings reaches above 10cm. The seed generation rate of the method is high and can reach 81.0-94.5%, and high seedling and seedling transplanting survival rate is achieved.

Description

technical field [0001] The invention relates to a method for seed propagation of the endangered and rare plant heteromorphic japonica japonica, belonging to the technical field of plant sexual reproduction. [0002] technical background [0003] Alien Jade Leaf Golden Flower ( Mussaenda anomala H.L.Li in Journ. Arn. Arb. 24(4):454.1943) is a national first-class key protected rare and endangered plant, which belongs to the Rubiaceae Jadeleaf plant, climbing shrubs, opposite leaves, thin paper, polychacymes Terminal, with many flowers, calyx tube oblong, about 5 mm long, calyx lobes 5, all white petal-shaped leaves, flower leaves ovate-elliptic, 2-4 cm long, with 5 longitudinal veins, The flowering period is June, and the fruiting period is November. The berry is 4 mm long, the seed diameter is 0.45-0.70 mm, and the thousand-grain weight is about 0.052 g. Endemic to my country, it is only produced in Dayao Mountain, Guangxi and southeastern Guizhou (Chinese Higher Plants Vol...
