Embodiment 1

[0051] Embodiment 1: a kind of using method of hijiki oligosaccharide, this using method comprises the following steps:

[0052] S1. Dilute hijiki oligosaccharides at a concentration of 0.05 g / L after freeze-drying; cultivate 1000 tobacco seeds with seedling trays. Six days after emergence, the tobacco seedlings were transplanted into 72-hole seedling trays. When the tobacco seedlings grew to 4 leaves and 1 heart, the robust and uniform seedlings were selected and transplanted into flower pots with a diameter of 9 cm. Each experiment Group treatment of 15 pots of tobacco seedlings.

[0053] S2, adopt root irrigation method to fertilize the plant seedlings, the dosage of each plant is 40ml, once every 4d, 2 times in total;

[0054] S3. Fertilize the plant seedlings by foliar spraying method, with a dose of 5 ml per plant, once every 4 days, 3 times in total.

[0055] All the rest of the time is watered on time, and the amount of water and the frequency of watering all adopt t...

Embodiment 2

[0087] Embodiment 2: a kind of using method of hijiki oligosaccharide, this using method comprises the following steps:

[0088] S1. Dilute hijiki oligosaccharides at a concentration of 0.08g / L after freeze-drying; cultivate 1000 tobacco seeds with seedling trays. Seven days after emergence, the tobacco seedlings were transplanted into 72-hole seedling trays. When the tobacco seedlings grew to 4 leaves and 1 heart, the robust and uniform seedlings were selected and transplanted into flower pots with a diameter of 9 cm. Each experiment Group treatment of 15 pots of tobacco seedlings.

[0089] S2, adopt root irrigation method to fertilize the plant seedlings, the dosage of each plant is 50ml, once every 5d, 2-4 times in total;

[0090] S3. Fertilize the plant seedlings by foliar spraying method, with a dose of 6 ml per plant, once every 5 days, 4 times in total.

[0091] All the rest of the time is watered on time, and the amount of water and the frequency of watering all adop...

Embodiment 3

[0123] Embodiment 3: a kind of using method of hijiki oligosaccharide, this using method comprises the following steps:

[0124] S1. Dilute hijiki oligosaccharides at a concentration of 0.1 g / L after freeze-drying; cultivate 1000 tobacco seeds with seedling trays. Eight days after emergence, the tobacco seedlings were transplanted into 72-hole seedling trays. When the tobacco seedlings grew to 4 leaves and 1 heart, the robust and uniform seedlings were selected and transplanted into flower pots with a diameter of 9 cm. Each experiment Group treatment of 15 pots of tobacco seedlings.

Abstract

The invention discloses a use method of sargassum fusiforme oligosaccharide. The use method comprises the following steps: S1, freeze-drying the sargassum fusiforme oligosaccharide, and diluting the freeze-dried sargassum fusiforme oligosaccharide with the concentration of 0.05-0.1 g / L; cultivating 1000 tobacco seeds by using a seedling raising plate; 6-8 days after seedling emergence, transplanting tobacco seedlings into 72-hole seedling raising trays, when the tobacco seedlings grow to have four leaves and one core, selecting and transplanting robust seedlings with consistent growth vigor into flowerpots with the diameter of 9 cm, and treating 15 pots of tobacco seedlings in each experimental group. S2, performing fertilization treatment on the plant seedlings by adopting a root irrigation method, controlling the dosage of each plant to be 40-60 ml, and performing fertilization treatment once every 4-6 days for 2-4 times in total; S3, adopting a foliage spraying method to conduct fertilization treatment on the plant seedlings, wherein the dosage of each plant is 5-7 ml, the fertilization treatment is conducted once every 4-6 days, and the total fertilization treatment is 3-5 times. Comprehensive results show that the sargassum fusiforme oligosaccharide has significant promotion effects on early growth, rapid growth, growth promotion and quality improvement of plants.

Description

technical field [0001] The invention relates to a method for using hijiki oligosaccharides. Background technique [0002] Tobacco is a very important economic crop in my country, and tobacco cultivation technology has a great influence on the development of my country's tobacco industry and market economy. High-quality and efficient cultivation of tobacco can significantly improve the quality and yield of tobacco, and increase the economic benefits of tobacco farmers and suppliers. At present, the quality of tobacco is not only related to the economic interests of growers, but also to a certain extent can promote the healthy development of social economy. Therefore, the scientific cultivation of tobacco is extremely important. [0003] In recent years, due to the unique advantages of seaweed polysaccharides in agricultural production, the research on polysaccharides has gradually increased, but there are few reports on the application of oligosaccharides in agriculture. S...
