Problems solved by technology

The main problem in the cultivation technology of Nepalese yellow flower seedlings is that its seed coat is hard, which restricts the germination of seeds and causes great difficulty in sowing seedlings. Most of the existing tree seeding technologies cannot solve this problem well.

Embodiment 1

[0022] A method for sowing and raising seedlings of Nepalese yellow flowers, comprising the following steps:

[0023] 1. Seed collection:

[0024] Choose a healthy mother tree, pick seeds from mid-September to early October, and harvest the fruits in time when the pods turn from green to yellow-brown. The harvested pods are dried in the sun, the pods are cracked, the seeds are taken out, impurities and empty and damaged seeds are removed to obtain plump seeds with a clarity of more than 90%, which are sealed in ziplock bags and placed Store in a freezer at 4-6°C for later use.

[0025] 2. Seed treatment:

[0026] Take the seeds and place them in KMnO with a mass concentration of 0.5% 4 Soak in an aqueous solution to achieve the effect of disinfecting the surface of the seeds. After soaking for 30 minutes, take out the seeds to dry the surface moisture; soak the surface-sterilized seeds in distilled water at 80°C, and place the beaker in which the seeds are soaked in a water...

Embodiment 2

[0032] Effects of soaking in constant temperature water at different temperatures on seed germination:

[0033] Take 100 seeds and place them in KMnO with a mass concentration of 0.5% 4 Soak in the aqueous solution to achieve the effect of disinfecting the surface of the seeds. The volume of the solution is 100ml. After soaking for 30 minutes, take out the seeds and dry the surface moisture. Soak the surface-sterilized seeds in distilled water at different temperatures, use a 300mml beaker for the container, and set the water temperature to 70°C, 80°C, and 90°C, respectively, and place the beaker in which the seeds were soaked in a water bath to keep warm; the treatment time is 5min. , 10min. Three replicates were set, and the seeds directly sown without soaking were used as controls. The treated seeds were sown according to the above method, and the statistics of the emergence rate after 30 days were shown in Table 1. The seedling emergence rate of soaking in hot water at ...

Embodiment 3

[0037] Effects of water immersion at different temperatures on seed germination:

[0038] Take 100 seeds and place them in KMnO with a mass concentration of 0.5% 4 Soak in the aqueous solution to achieve the effect of disinfecting the surface of the seeds. The volume of the solution is 100ml. After soaking for 30 minutes, take out the seeds and dry the surface moisture. The surface-sterilized seeds were immersed in distilled water of different temperatures, and the container was a 300-mml beaker. The water temperature at the beginning was set to 30 ° C and 60 ° C, respectively, and then it was allowed to cool naturally, and stirred several times during the period to promote the seeds to absorb water. After 24 hours, the cooled water was poured out and replaced with hot water for immersion, and the water was changed once a day; the treatment time was 3 days and 6 days respectively. Three replicates were set, and the seeds directly sown without soaking were used as controls. T...

Abstract

The method comprises the following steps: collecting seeds, selecting healthy seed trees, and harvesting fruits in time when legumes become yellowish-brown from green; the harvested pods are placed in the sun to be dried, the pods are made to crack, and seeds are taken out; seed treatment: soaking the seeds subjected to surface disinfection in distilled water at 80 DEG C, and placing a beaker for soaking the seeds in a water bath kettle for heat preservation for 10 minutes; or soaking in distilled water with the temperature of 60 DEG C, wherein the treatment time is 6 days respectively; or the seeds are rubbed by abrasive paper; seedling blocks are used as sowing substrates, sowing is performed after watering is performed for one day, and treated seeds are buried in the middles of the surfaces of the seedling blocks with the depth of 0.5-1 cm. According to the method for sowing and seedling raising of the dalbergia odorifera seeds, physical dormancy of the dalbergia odorifera seeds can be effectively broken, the germination rate of the seeds is increased, the sowing and seedling raising period is shortened, and the breeding problem is solved.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for sowing and raising seedlings of Nepalese yellow flowers. Background technique [0002] Nepal yellow flower, also known as golden chain leaf yellow flower, is an evergreen shrub of the leguminous family. It is produced in Tibet and Yunnan, and is born in the alpine mountains with an altitude of about 3,000 meters. It is distributed on the edge of coniferous forests on hillsides, grasslands and shrubs or beside rivers. It is also distributed in Nepal, Bhutan, and Kashmir. Its plants are lush and leafy, evergreen in all seasons, with yellow flowers blooming from April to July, dense inflorescences, golden trees in full bloom, bright and dazzling, and the flowering period lasts for several months. It is a very good local ornamental plant. In alpine regions, it grows faster, has few pests and diseases, and has strong drought resistance and barren resistance. It ...
