Problems solved by technology

[0003] However, the distribution of A. glabrata is remote, and there is no artificial cultivation in China, and there are only a few botanical gardens in foreign countries that have species preservation.
[0004] Apply conventional methods to sow and raise seedlings of S. glabrata, usually the emergence rate is less than 5%, and the emergence period is long, it is difficult to obtain a large number of neat and strong seedlings, and the reproductive efficiency is very low
There are very few research reports on the genus Chrysanthemum at home and abroad, and the research on seedling cultivation at home and abroad is currently blank

Embodiment 1

[0035] Embodiment 1, the influence of different treatments on the imbibition rate and germination rate of Chrysanthemum glabra seeds

[0036] The method of measuring the imbibition rate is as follows: randomly select a certain number of A. glabrata seeds; soak the seeds in normal temperature water on the first day, and then change the initial temperature every day to 15-25°C, 50°C-60°C and 80°C-100°C. Soak the seeds in clear water at a higher temperature, so that the water temperature will naturally drop to room temperature. Soak the seeds for a total of 10 days. Pick out the imbibition seeds before changing the water at different temperatures, record the number of imbibition seeds per day, and use the following formula to calculate the imbibition rate of different water temperatures:

[0037]

[0038] The calculation method of hard solid rate is:

[0039] Hard solid rate (%)=1-imbibition rate

Embodiment 2

[0053] Embodiment 2, the comparative experiment of conventional sowing of glabra japonica seeds and the raising of seedlings of the present invention

[0054] In this experiment, the seeds of A. glabrata collected in October 2009 were selected. Threshing and net seeding by conventional methods, put them into sealed plastic bags and store them in a refrigerator at 0°C to 5°C to keep them moist and refrigerated. Randomly select 400 seeds for each treatment, and divide them into 4 repetitions, with 100 seeds per repetition; soak the seeds in water for 48 hours before storing in sand, and use Wet sand was layered for 0, 1, 2, 3, and 4 months; on February 28, 2011, seeds were sown in a non-heated glass greenhouse at the same time. The method of the present invention was used as a contrast, soaking seeds in clear water for 1 day on March 1, soaking seeds in 80-100°C high-temperature water naturally down to room temperature for 5 days from March 2 to March 6, and 98% concentrated sul...

Embodiment 3

[0056] Embodiment 3, comparative test of industrialized seedling raising technology of A. glabrata

[0057] The sowing depth experiment of industrialized seedling cultivation selects the uniform seedlings germinated by this technology, and uses 3 treatments with soil covering depths of 1 cm, 2 cm, and 3 cm in the uniformly prepared uniform cultivation medium for comparative experiments, and each treatment has 30 seedlings. Seeds germinated on the same day, 3 repetitions, observed and recorded the number of emergences per day, measured the height of the seedlings after 30 days, calculated the emergence rate and survival rate, the results are shown in Figure 7 . Figure 7 The picture on the left shows the emergence of seedlings at different sowing depths within 30 days of sowing. The first emergence time of 1 cm, 2 cm, and 3 cm was 6 days, 8 days, and 18 days respectively; the time to reach the maximum emergence rate was 17 days, 26 days, After 28 days, the maximum emergence r...

Abstract

The invention discloses an industrial piptanthus nepalensis f.leiocarpus seedling rearing method. A seed germination method provided by the invention comprises variable temperature imbibition, acid etching with 98% concentrated sulfuric acid, seed soaking in high-temperature water and constant temperature accelerating germination. The industrial seedling rearing method provided by the invention comprises a method for comprehensively regulating and managing such cultivation environment conditions as sowing and covering depth, cultivation substrate ratio, illumination, moisture and pH value. Byutilizing the industrial seedling rearing technology provided by the invention, the germination rate of piptanthus nepalensis f.leiocarpus seeds can be improved by 80%, the seedling rate can be improved by over 60% and the seedling rearing time is shortened by 90 days. The method provides feasible key technology for industrial piptanthus nepalensis f.leiocarpus seedling rearing.

Description

technical field [0001] The invention relates to a method for industrialized seedling cultivation of A. glabrata. Background technique [0002] Piptanthus nepalensis f.leiocarpus, Fabaceae, Piptanthus nepalensis, variant of Piptanthus nepalensis, evergreen shrub, distributed in Tibet, Yunnan, Qinghai, Nepal; unique plant on the Qinghai-Tibet Plateau. This species likes a warm and humid climate, and is mostly distributed in sandy soil on hillsides with good drainage. It likes light and is resistant to barrenness; the crown of the plant is plump, the branches and leaves are lush and dark green, and the flowers are bright yellow; the branches, leaves and seeds are rich in protein, fat and amino acids. and other nutrients. Because of its luxuriant branches and leaves, evergreen in four seasons, strange leaf shape, and various flowers, it has high ornamental value; the seeds are rich in nutrition, high in yield, and have potential feeding value; at the same time, it has wide adap...
