Embodiment 1

[0025] A kind of efficient method for accelerating germination and raising seedlings of lettuce seeds, comprising the following steps:

[0026] (1) Seed pretreatment: select lettuce seeds that are plump, free from mildew, moth-eaten and shriveled, and placed in room temperature and relative humidity of 40% to naturally spread for 5 days, and often turn the ground when drying the seeds, and strive to dry them. uniform, and then placed in the shade at 20°C without light for 2 days;

[0027] (2) Seed soaking and disinfection: Soak the seeds obtained in step (1) in disinfectant solution for 10 minutes to sterilize, then soak in seed soaking agent for 2 hours, remove the seeds and wash them with clean water before accelerating germination;

[0028] (3) Temperature-changing germination: Mix the soaked and sterilized seeds in step (3) evenly with the germination matrix, put them into a breathable gauze-wrapped bag, and place the gauze-wrapped bag flat in a constant temperature cultur...

Embodiment 2

[0038] A kind of efficient method for accelerating germination and raising seedlings of lettuce seeds, comprising the following steps:

[0039] (1) Seed pretreatment: select lettuce seeds that are plump, free from mildew, moth-eaten and shriveled, and placed in the air at room temperature and relative humidity of 50% for 7 days, and often turn over the ground when drying the seeds, and strive to dry them. uniform, and then placed in the shade at 30°C without light for 4 days;

[0040] (2) Seed soaking and disinfection: soak the seeds obtained in step (1) in a disinfectant solution for 20 minutes to sterilize, then soak in a seed soaking agent for 4 hours, remove the seeds and wash them with clean water before accelerating germination;

[0041] (3) Temperature-changing germination: Mix the soaked and sterilized seeds in step (3) evenly with the germination matrix, put them into a breathable gauze bag, and place the gauze bag flat in a constant temperature culture room at 40°C f...

Embodiment 3

[0051] A kind of efficient method for accelerating germination and raising seedlings of lettuce seeds, comprising the following steps:

[0052] (1) Seed pretreatment: select lettuce seeds that are plump, free from mildew, moth-eaten and shriveled, and placed in the air at room temperature and relative humidity of 45% for 6 days, and often turn over the ground when drying the seeds, and strive to dry them. uniform, and then placed in the shade at 25°C without light for 3 days;

[0053] (2) Seed soaking and disinfection: soak the seeds obtained in step (1) in a disinfectant solution for 15 minutes to sterilize, then soak in a seed soaking agent for 3 hours, remove the seeds and wash them with clean water before accelerating germination;

[0054] (3) Temperature-changing germination: Mix the soaked and sterilized seeds in step (3) evenly with the germination matrix, put them into a breathable gauze bag, and place the gauze bag flat in a constant temperature culture room at 35°C f...

Abstract

The invention discloses a high-efficiency germination and seedling breeding method for lettuce seeds. The method comprises the steps of (1), preprocessing of seeds; (2) soaking of the seeds and disinfecting: the seeds are firstly placed in disinfectant and soaked for 10-20 min for disinfection, and the seeds are placed in a seed-soaking agent to be soaked for 2-4 hours; (3) germinating by changingtemperature; (4) sowing and seedling breeding: the seeds are sowed in a seedling breeding medium applied with fertilizers and cultivated until the seeds germinate. By means of the method, the germination time can be shortened to improve the germination rate and germination index of the lettuce seeds, the quality of seedling trees is further improved, and the method has significant value on the production and using of lettuces.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for efficiently accelerating germination and raising seedlings of lettuce seeds. Background technique [0002] Lettuce, also known as lettuce, is a one-two-year-old herb that can form a variety of fleshy tender stems. . Lettuce can be divided into two types for stems and leaves. Stem lettuce is fresh and tender, and can be eaten raw, cold, fried, dried or pickled; leaf lettuce mainly eats leaves or leaf bulbs. Lettuce is widely cultivated all over the world and has become the main vegetable that people like. The content of carbohydrates in lettuce is low, while the content of inorganic salts and vitamins is relatively rich, especially niacin; for patients with high blood pressure and heart disease, it has the effect of diuresis and lowering blood pressure. Lettuce also has the functions of increasing appetite, stimulating the secretion of digestive juic...
