Embodiment Construction

[0013] A method for raising seedlings with high germination rate of lettuce seeds, comprising:

[0014] 1) Preparation of lettuce seeds: choose naturally mature and robust lettuce seeds for seedling cultivation;

[0015] 2) Soaking pretreatment of lettuce seeds: Soak lettuce seeds in a 2% sodium bicarbonate solution at 30-35°C for 1 hour, which can break the dormancy of the seeds to a certain extent and improve the permeability of the seed coat nature, then take it out and drain;

[0016] 3) Chemical treatment of lettuce seeds: Soak lettuce seeds for 4-6 hours with chemical agents, which are composed of 2% sodium chloride, 0.1% bark tree sap, 0.5% vitamin B12, and the rest are water. The interaction of components can further break the dormancy of seeds, improve the permeability of the seed coat, enhance cell respiration, and promote cell division;

[0017] 4) Disinfection of lettuce seeds: The above lettuce seeds are soaked in a mixed solution of 0.1% potassium permanganate,...

Abstract

E invention discloses an asparagus lettuce seedling culture method capable of realizing a high germination rate. The method comprises the steps of asparagus lettuce seed preparation, asparagus lettuce seed soaking pretreatment, asparagus lettuce seed pharmaceutical treatment, asparagus lettuce seed sterilization, asparagus lettuce seed germination acceleration and asparagus lettuce seed sowing. Compared with existing asparagus lettuce seedling culture techniques, the method has the advantages that the germination rate of seeds is 94.3-96.4%, seedling survival rate after transplantation is 89.9-94.4%, the cultured seedlings are high in growth vigor and have a strong root system and high disease resistance, the occurrence rate of downy mildew and black spot is reduced remarkably in the culture period, adaptability is high after transplantation, the cold resistance of asparagus lettuce can be improved, the content of iron, the content of zinc and the content of selenium in cultured asparagus lettuce are increased by 11%, 15% and 5% respectively, comprehensive nutritive value is increased remarkably, asparagus lettuce stems are more robust, the content of dietary fiber is increased obviously, taste is good, yield is high, and economic benefits are high.

Description

technical field [0001] The invention relates to the field of planting, in particular to a seedling raising method with high germination rate of lettuce seeds. Background technique [0002] Lettuce is lettuce for stems. Its above-ground stems are crisp and tender, and delicious. Seedling survival rate is low, thereby can increase production cost. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, the invention provides a seedling raising method with high germination rate of lettuce seeds. [0004] The present invention is realized through the following technical solutions: [0005] A method for raising seedlings with high germination rate of lettuce seeds, comprising: [0006] 1) Preparation of lettuce seeds: choose naturally mature and robust lettuce seeds for seedling cultivation; [0007] 2) Soaking pretreatment of lettuce seeds: Soak lettuce seeds in a 2% sodium bicarbonate solution at 30-35°C for 1 hour, which can break the do...
