Problems solved by technology

[0002] Pittosporum alias, Pittosporum flower, mountain alum, roots, leaves and seeds are used as medicine, roots can dispel wind, activate collaterals, dissipate blood stasis and relieve pain; leaves can detoxify and stop bleeding; seeds can astringe intestines and strengthen essence; Pittosporum also has a great ornamental effect It has strong resistance to toxic gases such as sulfur dioxide. With the development of greening, the demand for Pittosporum is increasing. However, the sowing and reproduction rate of Pittosporum is relatively low, and the germination rate can only reach 50%. About 60-70 days after sowing, it can germinate, which obviously increases the cost of planting. Therefore, there is a need for a preservation method to accelerate the germination of Pittosporum seeds

Embodiment 1

[0016] A preservation method for accelerating the germination of Pittosporum seeds, comprising the following steps:

[0017] (1) Seed pretreatment: After picking Pittosporum seeds, remove immature and damaged seeds, and immediately spray diesel oil solution, the spraying amount is 23% of the weight of Pittosporum seeds, adding Pittosporum bark, can inhibit bacteria and insects, and promote diesel oil. The absorption of the solution increases the pH of the seeds, regulates the physiological hormones of the seeds, reduces the activity of the germ-inhibiting substances in the seeds, shortens the dormant period of the seeds, mixes them evenly, and stands at -12°C for 40 hours, rubs off the seed coats, and obtains pretreatment seed;

[0018] (2) Seed sterilization: Add the fungicide solution to the pretreated seeds, the amount added is 21% of the weight of the seeds, and stand at 4°C for 50 hours, which can not only inhibit bacteria and kill insects, but also provide more nutrients...

Embodiment 2

[0025] A preservation method for accelerating the germination of Pittosporum seeds, comprising the following steps:

[0026] (1) Seed pretreatment: After the Pittogonia seeds are picked, remove the immature and damaged seeds, and immediately spray the diesel solution, the spraying amount is 23~25% of the weight of the Pittogonia seeds, and add Pittogonia bark, which can inhibit bacteria and kill insects. Promote the absorption of diesel oil solution, increase the pH of seeds, adjust the physiological hormones of seeds, reduce the activity of germination-inhibiting substances in seeds, shorten the dormant period of seeds, mix well, stand at -12~-10°C for 40~45 hours, rub To remove the seed coat, the seeds have to be pretreated;

[0027] (2) Seed sterilization: add the fungicide solution to the pretreated seeds, the amount added is 21-23% of the weight of the seeds, and stand at 4-8°C for 50-55 hours, which can not only inhibit bacteria and kill insects, but also provide seeds ...

Embodiment 3

[0034] A preservation method for accelerating the germination of Pittosporum seeds, comprising the following steps:

[0035] (1) Seed pretreatment: After the Pittogonia seeds are picked, remove the immature and damaged seeds, and immediately spray the diesel solution, the spraying amount is 23~25% of the weight of the Pittogonia seeds, and add Pittogonia bark, which can inhibit bacteria and kill insects. Promote the absorption of diesel oil solution, increase the pH of seeds, adjust the physiological hormones of seeds, reduce the activity of germination-inhibiting substances in seeds, shorten the dormancy period of seeds, mix well, stand at -12~-10°C for 40~45 hours, rub To remove the seed coat, the seeds have to be pretreated;

[0036] (2) Seed sterilization: add the fungicide solution to the pretreated seeds, the amount added is 21-23% of the weight of the seeds, and stand at 4-8°C for 50-55 hours, which can not only inhibit bacteria and kill insects, but also provide seeds ...

Abstract

The invention mainly relates to the technical field of planting and discloses a preservation method capable of quickening pottosporum tobira seed germination. The preservation method comprises the steps of seed pretreatment, seed sterilizing, seed drying and seed preservation; the preparation method is simple and convenient to operate; germination time of pottosporum tobira seeds can be shorted to 15 to 20 days, the germination rate can reach 91.3%, a lot of planting cost is saved, and economical income is improved by 21.6%. After the pottosporum tobira seeds are picked, diesel solution and pottosporum tobira bark are added to inhibit bacteria and kill insects, diesel solution absorption is improved, seed pH is improved, physiological hormone of seeds is adjusted, activity of sprout inhibition matter in the seeds is reduced, and seed germination is quickened. Bactericide solution is added into the seeds, so that not only antibacterial and insecticide effects are achieved, but also more nutritional ingredients are provided for the seeds, seed germination is activated, a seed dormancy period is shortened, evaporation of water in the seeds is slowed down, and seed germination is quickened. The sterilized seeds are frozen and dried to keep nutritional ingredients and germinating ability of the seeds, so that seed germination time is shortened.
