Problems solved by technology

In addition, after soaking a batch of sugarcane seedlings for a certain period of time, the next batch of sugarcane seedlings can be soaked. Continuous soaking for a long time will easily cause damage to the roots. The soaked sugarcane seedlings must be dried before being transferred. To plant sugar cane, time-consuming and labor-intensive
Therefore this traditional sugarcane seedling soaking workload is very big, loaded down with trivial details
In the current situation of labor shortage and high cost, it is difficult to promote it in a large area in actual production, and it is also difficult to meet the requirements of mechanized mass production

Embodiment 1

[0023] The present embodiment provides a kind of disinfection method of sugarcane seedling, comprises the steps:

[0024] S1, directly choose a piece of 40-50m in the field of sugarcane 2 Spread a layer of colored striped cloth on the open space, which is relatively flat, as a disinfection site.

[0025] S2, stacking the sugarcane seedlings to be sterilized in the disinfection site to form a sugarcane seedling pile:

[0026] Specifically, in this step, the process of forming a heap of sugarcane seedlings is as follows: the cut down sugarcane seedlings to be sterilized are bundled at 10-30 kg / bundle to form a heap of sugarcane seedlings, and then a plurality of sugarcane seedlings are heaped Stack in the field for disinfection to form a sugarcane seedling heap of (5-10) m x (3-8) m x (2-3) m in length x width x height. When stacking, try to make the sugarcane seedlings sub-heap have gaps so that the disinfection and sterilization liquid can effectively penetrate into the insi...

Embodiment 2

[0036] The present embodiment provides a kind of disinfection method of sugarcane seedling, comprises the steps:

[0037] S1, choose a piece of 40-50m directly in the sugarcane field 2 For a relatively flat open space, spread a layer of colored striped cloth on the open space as a disinfection site.

[0038] S2, stacking the sugarcane seedlings to be sterilized in the disinfection site to form a sugarcane seedling pile:

[0039] Specifically, in this step, the process of forming a pile of sugarcane seedlings is as follows: bundle the sugarcane seedlings to be sterilized at 15-25 kg / bundle to form a separate pile of sugarcane seedlings, and then stack multiple sugarcane seedlings in a sterile In the field, a sugarcane seedling pile of (6-8) m * (4-7) m * (2-3) m in length * width * height is formed. When stacking, try to make the sugarcane seedlings sub-heap have gaps so that the disinfection and sterilization liquid can effectively penetrate into the inside of the sugarcane ...

Embodiment 3

[0050] The disinfection method of the sugarcane seedling of the present embodiment is identical with the step of embodiment 1, and the difference is: the disinfection solution adopts the sclerotinium and the thiafuramide as the bactericidal preparation of the active ingredient with a weight ratio of 15-25:3-10, Sterilize sugarcane seedlings.

[0051] Mechanized planting of sugarcane seedlings prepared by the sugarcane seedling disinfection method obtained in Example 3 can reduce the incidence of red rot to below 8%.

[0052] The above-mentioned disinfection method for sugarcane seedlings is combined with the difficult problem of seedling disinfection treatment in the current mechanized planting of sugarcane, according to local conditions, directly select an open space on the edge of the sugarcane field, spread colored strips of cloth, and then it can be used as a place for disinfection, and can be directly After the cut sugarcane seedlings to be sterilized are stacked neatly o...

Abstract

The invention relates to a disinfecting method for sugarcane seedlings. The method comprises the following steps: directly selecting vacant land in a sugarcane field to be planted, and laying a substrate on the vacant land as a disinfection place; spraying a disinfection sterilization liquid to a pile of sugarcane seedlings piled on the disinfection place; and covering the pile of sugarcane seedlings sprayed by the disinfection sterilization liquid by a cover film, and performing disinfection treatment on the sugarcane seedlings. Compared with a traditional seed-soaking disinfecting method ofsugarcane seedlings, the disinfecting method for the sugarcane seedlings provided by the invention does not need to pre-treat newly-harvested sugarcane seedlings to be disinfected, does not need to set up a special disinfection place, enables the disinfection sterilization liquid to be fully infiltrated into the sugarcane seedlings to achieve the effects of sterilization and insect removal, enables the sugarcane seedlings to absorb enough moisture before being sown to increase a germination rate, can significantly save a large number of labor costs on the whole, and is suitable for large-areapromotion and mechanized large-scale production.

Description

technical field [0001] The invention relates to the field of sugarcane planting, in particular to a method for disinfecting sugarcane seedlings. Background technique [0002] Pineapple disease, smut, red rot, etc. are important soil-borne and seed-borne diseases of sugarcane seedlings. The incidence rate in the field is generally 10%-30%, and it can reach more than 50% in severe cases. After sugarcane is invaded by such pathogens, it will not only affect the germination of seedlings and the growth of cane seedlings, but also affect the normal development and sugar accumulation of sugarcane plants in the middle and late stages of sugarcane, resulting in reduced sugarcane yield and loss of sucrose content. Pineapple disease and smut can be prevented by soaking and disinfecting sugarcane seeds. Therefore, soaking and disinfection of sugarcane seedlings is an important technology for sugarcane seedling treatment, which is not only beneficial to the prevention and treatment of s...
