Embodiment 1

[0018] A processing method of tea tree seeds, comprising the following steps:

[0019] (1) Seed storage: Collect tea fruit that grows vigorously, has strong stress resistance, is ripe and plump, and cracks, soaks the tea fruit in a chitosan solution with a mass fraction of 0.6% at 38-40°C for 8 hours, and removes the peel , freeze-dry at -32~-30°C until the water content is 16~18%, melt the seed coat, provide nutrition, freeze-dry to promote the completion of dormancy of the seeds, store in the storage room, and obtain the seeds for propagation;

[0020] (2) Seed soaking: Soak the propagation seeds in an acetic acid solution with a temperature of 43~45°C and a volume fraction of 2% for 5 hours to accelerate the softening of the seed coat, lower the pH value, stimulate the activity of the germ, and accelerate germination, so that the seeds can be soaked ;

[0021] (3) Seed sterilization: Spray the soaked seeds with a fungicide solution with a mass fraction of 1.1%, the sprayin...

Embodiment 2

[0030] A processing method of tea tree seeds, comprising the following steps:

[0031] (1) Seed storage: Collect tea fruit that grows vigorously, has strong stress resistance, is ripe and plump, and cracks, and soaks the tea fruit in a chitosan solution with a mass fraction of 0.7% at 38-40°C for 8-10 hours. Remove the peel, freeze-dry at -31°C until the water content is 16-18%, melt the seed coat, provide nutrition, freeze-dry to promote the completion of dormancy of the seeds, store in the storage room, and obtain the seeds for propagation;

[0032] (2) Seed soaking: Soak the propagation seeds in an acetic acid solution with a temperature of 43-45°C and a volume fraction of 2% for 5-6 hours to accelerate the softening of the seed coat, lower the pH value, stimulate the activity of the germ, and accelerate germination to obtain soak the seeds;

[0033] (3) Seed sterilization: Spray 1.2% of the fungicide solution on the soaked seeds, the spraying amount is 13% of the weight o...

Embodiment 3

[0042] A processing method of tea tree seeds, comprising the following steps:

[0043] (1) Seed storage: Collect tea fruit that grows vigorously, has strong stress resistance, is ripe and plump, and cracks, and soaks the tea fruit in a chitosan solution with a mass fraction of 0.8% at 38-40°C for 8-10 hours. Remove the peel, freeze-dry at -30°C until the water content is 16-18%, melt the seed coat, provide nutrition, freeze-dry to promote the completion of dormancy of the seeds, store in the storage room, and obtain the breeding seeds;

[0044] (2) Seed soaking: Soak the propagation seeds in an acetic acid solution with a temperature of 43-45°C and a volume fraction of 3% for 5-6 hours to accelerate the softening of the seed coat, lower the pH value, stimulate the activity of the germ, and accelerate germination to obtain soak the seeds;

[0045] (3) Seed sterilization: Spray soaked seeds with a fungicide solution with a mass fraction of 1.3%, the spraying amount is 14% of th...

Abstract

The invention mainly relates to the technical field of planting, and discloses a method for treating tea tree seeds. The method comprises the following steps: preserving seeds; soaking the seeds; sterilizing the seeds; accelerating germination of the seeds; sowing the seeds. The method is simple, the germination rate of the tea tree seeds can be up to 91%, the pretreatment time before seeding can be shortened to 5-6 days, the sprouting time after direct seeding can be shortened to 8-9 days, the survival rate can be up to 94%, and the economic income can be increased by 18.3%; after being picked, tea tree fruits are soaked in a chitosan liquid, then seed coats can be softened, nutrition can be provided, dormancy completion can be accelerated through freeze drying, and germination can be accelerated; as the seeds are soaked in the chitosan liquid, softening of the seed coats can be accelerated, the pH value can be reduced, germ activity can be stimulated, and germination can be accelerated; after bactericide is sprayed, pathogenic microorganism multiplication can be inhibited; through plant extraction, multiple nutrient components can be available, and the survival rate can be increased; due to addition of zeatin and perindopril, seed germination can be promoted; the seeds are put into a germination accelerating tank, and a plant ash solution is sprayed, so that balanced nutrition can be provided, and the stress resistance can be improved.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a method for treating tea tree seeds. Background technique [0002] my country is the country with the largest tea production, and the planting of tea trees is also the most extensive. In the process of planting tea trees, the main propagation method is cutting propagation. The tea seedlings obtained by seed propagation have strong adaptability and simple cultivation, and most of them use seeds when breeding new varieties. Propagation, but seed dormancy needs to be broken during seed reproduction, and germination is slow. The seeds are stored in sand and soaked using traditional methods, and they will not be unearthed until 4 to 5 months after live broadcasting. The germination rate can only reach about 50%, which significantly reduces the planting efficiency. , Improve the planting cost of tea tree, therefore, need a kind of processing method that accelerates tea tree seed...
