Problems solved by technology

In addition, after tobacco is infected with the virus, the chlorophyll in the leaves will be destroyed by the virus, the ability of photosynthesis will be weakened, and the growth of the leaves will also be inhibited. Small leaves, deformed leaves, and short plants will eventually cause leaf quality to deteriorate and yield to decrease.

Embodiment 1

[0021] Tobacco plantation land is selected in areas without obvious freezing damage, non-low-lying land and cold air that are not easy to stagnate. It requires deep soil, good drainage and ventilation, rich organic matter, convenient irrigation, and convenient transportation. Choose disease-free seedlings for planting. After the seedlings are planted, start to spray the photosynthetic high-lipid film agent solution to promote growth and prevent diseases.

[0022] The method of utilizing photosynthetic high-fat film agent to prevent and control tobacco virus disease provided by the present embodiment includes photosynthetic high-fat film agent, and the photosynthetic high-fat film agent is composed of the following components by weight ratio: 180 parts of lauryl alcohol, cetyl alcohol 120 parts, 8 parts of emulsifier, 5 parts of co-emulsifier, 40 parts of thickener, 800 parts of water; During the period of topping and wiping, the tobacco is sprayed.

[0023] The emulsifier is...

Embodiment 2

[0039] The present embodiment provides a kind of method that utilizes photosynthetic high-fat film agent to prevent and control tobacco virus disease, compared with embodiment 1, difference is:

[0040] The emulsifier is high-carbon fatty alcohol polyoxyethylene ether.

[0041] The co-emulsifier is propylene glycol.

[0042] The thickener is methyl cellulose.

Embodiment 3

[0044] The present embodiment provides a kind of method that utilizes photosynthetic high-fat film agent to prevent and control tobacco virus disease, compared with embodiment 1, difference is:

[0045] The emulsifier is sorbitan ester.

[0046] The co-emulsifier is propylene glycol.

[0047] The thickener is xanthan gum.

[0048] Compared with traditional cultivation techniques, the present invention has the following advantages:

[0049] By using the photosynthetic high-fat film agent, the invention can not only enhance the photosynthesis of the plant, promote the strong growth of the plant, improve the resistance ability of the plant itself to the pathogen, but also inhibit the further diffusion of the pathogen, thereby achieving the purpose of disease prevention. Photosynthetic high-lipid film agent has a good control effect on most fungal diseases. Its disease prevention is a physical effect, and the bacteria will not produce drug resistance. It is non-toxic and harmles...

Abstract

A method of preventing and controlling tobacco viral diseases via a photosynthetic high-fat membrane agent is provided. The photosynthetic high-fat membrane agent included herein comprises, by weight,180 parts of 1-dodecanol, 120 parts of 1-hexadecanol, 8 parts of an emulsifying agent, 5 parts of a co-emulsifier, 40 parts of a thickener, and 800 parts of water. After being diluted with water, thephotosynthetic high-fat membrane agent is sprayed to tobacco in its seedling stage, seedling resuscitation stage, root extending stage, prosperous growth stage and topping and sucker-smearing stage.Compared with the prior art of cultivation, the method has the advantages that the method herein helps enhance photosynthetic effect of a plant to promote vigorous growth of the plant and to improve viral resistance in the plant, and the method also helps inhibit further spread of viruses.

Description

technical field [0001] The invention relates to a method belonging to the technical field of agricultural plant protection, in particular to a method for preventing and controlling tobacco virus disease by using a photosynthetic high-fat film agent. Background technique [0002] Tobacco (scientific name: Nicotiana tabacum L.) is a plant of the genus Nicotiana in the Solanaceae family, an annual or limited perennial herb. Originally produced in South America, it is now widely cultivated in various provinces in the north and south of China. It is widely planted in every corner from 55° north latitude to 40° south latitude, but its most suitable planting area is very narrow. In addition, it likes temperature and is more sensitive to temperature response. Different temperature conditions have a greater impact on its quality and yield. The temperature requirements of high-quality tobacco during the growth period are low in the early stage and high in the late stage. Tobacco, a...
