Embodiment 1

[0017] 1. Seed production: 'primula 'qunshinaochun' was used in the greenhouse to perform seed production by using a mixed pollination method of artificial, honeybee and opening screen windows to increase ventilation. The specific method is: artificial pollination: during the blooming period of the spring flowers of the group of lions, artificial pollination is carried out from 9:00 to 11:00 in the morning, and the pollen on the stamens of short-style flowers is dipped with a brush, and it is pollinated on the stigma of long-style flowers; bee pollination: in the evening Put the bee colony into the greenhouse at the same time, open the nest door before dawn the next day, let the bees test fly, excrete, and adapt to the environment. There are two beehives in the 1000 square meter greenhouse. At the same time, the skylight and side windows of the greenhouse are fully opened to increase ventilation to increase the rate of firmness. The windows are opened to increase ventilation;...

Abstract

The invention provides a seed seedling culture method of a new species of Primula 'qunshinaochun', comprising the following steps of seed production and seed seedling culture, wherein the seed production is as follows: pollinating for 20 days by using a pollination method artificially mixing honeybee, anemophily, and the like so that fruits are gradually ripe from an outermost layer to an inner layer of an inflorescence; picking in batches during picking, and carrying out seed treatment and storage. The seedling culture is seed propagation seedling culture as follows: firstly, laying a sowing seedling bed, and filling turfy soil and perlite with the ratio of 3:2, wherein the pH value is equal to 6-6.5; currently spraying matched soil to be wet before sowing, then uniformly blending one part of seeds and 500 parts of river sands, and then sowing on the matched soil; and conventionally spraying water. The invention achieves the seed germination rate more than 95 percent and the transplantation survival rate of seedlings by almost 100 percent, shortens the seedling forming time of 10 months from sowing to flowering, has low cost, easy implementation and good effect, and provides the technical support for the large-scale culture of the species.

Description

Technical field: [0001] The invention relates to flower seed production and seed seedling raising methods, in particular to the seed production and seed seedling raising methods of primrose 'group lions making spring'. technical background: [0002] Primula 'Group Lions Naochun' is artificially crossed with Primula denticulatessp.sinodenticulata Balf.f.et Forr. W.W.Smith as the female parent and Primula pseudodenticulata Pax as the male parent produced varieties. This variety is a 1-2-year-old herbaceous flower with two types of flowers. It is a typical cross-pollinated plant. The whole plant is rosette-shaped, with well-developed rhizomes and 2-5 leaf clusters growing upward. The flowering period is from January to March, the flowers are purple, with 5-10 flower heads, the inflorescences are large, the height of the scape is 25-60cm, and the ornamental value is high. Has high commercial value. 'Lion Naochun' can reproduce sexually and asexually, but due to the high rate ...
