Embodiment 1

[0014] Take 60g of hypromellose (HPMC), add 1000ml of hot water at 80°C, stir to fully dissolve to obtain an aqueous solution of water-soluble film-forming material; take 100g of Panax notoginseng polysaccharide, add 1000ml of water, stir to fully dissolve, and then centrifuge at 5000rpm After 15 minutes, remove the precipitate and add water to make up to 1000ml of Panax notoginseng polysaccharide aqueous solution; mix the above two aqueous solutions evenly, add 3.4g of strong rooting and seedling strengthening agent, 0.14g of salicylic acid, 2g of 10% wettable polyoxin, and sclerotia Net 2g, stir well to make it evenly mixed.

[0015] When digging the notoginseng seedlings, dip the protective film of the notoginseng seedlings prepared above while digging, put them into the transport box, and plant them in the field one day later. At the same time, using the traditional method for comparison, the results are as follows:

[0016]

[0017] From the above results, it can be s...

Embodiment 2

[0019] Take 30g of hypromellose (HPMC) and 30g of carboxymethyl chitosan, add 1,000ml of hot water at 60°C, stir to fully dissolve to obtain an aqueous solution of water-soluble film-forming material; take 100g of notoginseng polysaccharide, add 1,000ml of water, Stir to make it fully dissolved, then centrifuge at 5000rpm for 15min, remove the precipitate, add water and adjust the volume to 1000ml to obtain a Panax notoginseng polysaccharide aqueous solution; mix the above two aqueous solutions evenly, add 3.4g of strong rooting and seedling strengthening agent, 0.14g of oxalic acid, 10% wettable polysaccharide Antimycin 2g, sclerotia 2g, stir well to make it evenly mixed.

[0020]

[0021] From the above results, it can be seen that the use of the protective film of the notoginseng seedlings of the present invention can greatly reduce the skin damage caused by the notoginseng seedlings during transplanting and transportation, thereby greatly reducing the risk of germ infect...

Embodiment 3

[0023] Take 1788 50g of polyvinyl alcohol, add 1000ml of hot water at 70°C, stir to fully dissolve to obtain an aqueous solution of water-soluble film-forming material; take 100g of Panax notoginseng polysaccharide, add 1000ml of water, stir to make it fully dissolved, and then centrifuge at 5000rpm for 15min to remove the precipitate Add water to make up to 1000ml panax notoginseng polysaccharide aqueous solution; mix the above two aqueous solutions evenly, add 0.4g of 3-indolebutyric acid (dissolved with a small amount of ethanol first), 1g of benzoic acid, 2g of 10% wettable polyoxin 1. Sclerotin 2g, metalaxyl 2g, fully stirred to make it evenly mixed.

Abstract

The invention relates to a panax notoginseng seedling protection film, and a preparation method and an application thereof. The film provided by the invention is a water-soluble gel prepared by using a water-soluble film-forming material, panax notoginseng polysaccharide, a root growth promoter, a preservative, and a pesticide. With the material, a protection film can be formed on the surface of a panax notoginseng seedling. With the panax notoginseng seedling protection film provided by the invention, water loss of panax notoginseng seedling during a transplanting process can be reduced, and seedling surface skin damage caused by abrasion during transportation or during transplanting can be reduced. Therefore, fungal infection or insect attack caused by damages after transplanting can be reduced, occurrence rate of panax notoginseng root rot, sclerotinia stem rot, sheath blight, anthracnose, and blight can be reduced, and panax notoginseng survival rate can be improved. The panax notoginseng seedling protection film provided by the invention has good physiochemical performances such as film-forming performance, water resistance, air permeability, water permeability, and the like. Therefore, healthy growth of crops can be protected.

Description

technical field [0001] The invention relates to a protective film for notoginseng seedlings, a preparation method and application thereof. Background technique [0002] Panax notoginseng ( Panax notoginseng (Burk.) F.H.Chen), also known as Tianqi, Jinbuhuan, etc., belongs to the genus Panax (Araliaceae). Panax )plant. Panax notoginseng is a famous and precious traditional Chinese medicine with a long history of utilization. In recent years, with the further study of the pharmacological effects of Sanqi, the demand for Sanqi is increasing. However, the continuous cropping obstacles and diseases of Sanqi seriously affect the output of Sanqi, which makes the price of Sanqi increase rapidly. Therefore, to overcome Continuous cropping obstacles, reducing and preventing diseases have become urgent problems to be solved in the current Panax notoginseng industry. Panax notoginseng is a perennial plant, which is usually harvested after one year of seedling transplantation and t...
