Microwave pre-treatment method for tea tree seeds

Abstract

The invention discloses a microwave pre-treatment method for tea tree seeds. The microwave pre-treatment method comprises the following steps: (1) selecting high-quality tea tree seeds and spreading the tea tree seeds in an indoor shady and cool, dried and ventilated place; removing rotted tea tree seeds; (2) immersing the tea tree seeds with warm water at 40 DEG C to 50 DEG C for 2min to 3min; adding sodium sorbate which accounts for 0.5 percent to 0.7 percent of the weight of the tea tree seeds and immersing for 8min to 10min; taking out the tea tree seeds and washing with water; (3) uniformly and flatly spreading the tea tree seeds into a container, adjusting microwave power and microwave time and carrying out microwave treatment on the tea tree seeds until the final temperature reaches 80 DEG C to 150 DEG C; (4) putting the tea tree seeds subjected to the microwave treatment into warm water at 42 DEG C and immersing for 2h to 4h; taking out the tea tree seeds and draining; uniformly spraying a gibberellin solution with the mass concentration of 0.4mg/L to 0.5mg/L, wherein the spraying amount is 7ml/Kg to 9ml/Kg; putting the tea tree seeds into a refrigerator at 3 DEG C to 4 DEG C and turning for one time every day; refrigerating for 3 to 4 days and washing the seed with clean water at 2 DEG C to 4 DEG C.

Description

technical field [0001] The invention relates to the technical field of seed treatment, in particular to a microwave pretreatment method for tea tree seeds. Background technique [0002] Tea tree, formerly known as: tea, a shrub or small tree of the family Theaceae, Camellia, with glabrous twigs. Leaves leathery, oblong or elliptic. The leaves of the tea tree can be used to make tea, and the seeds can be used to extract oil. The material of the tea tree is fine and dense, and its wood can be used for carving. The distribution is mainly concentrated between 16 degrees south latitude and 30 degrees north latitude. Tea trees like warm and humid climates. The buds start to germinate when the average temperature is above 10°C, and the optimum temperature for growth is 20-25°C; the annual precipitation should be above 1000 mm; Sun-loving and shade-tolerant, it is suitable for growing under diffuse light; its life is divided into seedling stage, juvenile stage, adult stage and sen...

Problems solved by technology

[0003] However, at present, the tea tree seeds are not pretreated, and the tea tree seeds are germinated directly by the nutrition provided by the germination bacteria. During the tea tree planting process, the seed germination rate is low, and the tea yield is low.
