Problems solved by technology

[0002] Sugarcane smut caused by Ustilago smut is one of the most economically harmful major sugarcane diseases in my country at present, seriously affecting the yield and quality of sugarcane. Studies have shown that when smut is severe, sugarcane yield can be reduced by as much as 30%. At the same time, it will also affect the growth of ratoon cane in the following year, especially the incidence of smut in rattan cane increases year by year, the yield of rattan cane decreases, and the life of rattan is getting shorter and shorter, which seriously threatens the healthy development of sugarcane production and the sugar industry.
The main varieties planted in my country's sugarcane areas all have the problem of high incidence of smut, and there is currently a lack of effective control measures

Embodiment

[0049] The planting method of embodiment comprises the following measures:

[0050] 1) Sowing for soil preparation: Ditch and ridge the field, first sprinkle quicklime in the planting ditch, cover with plastic film, and sow after 7 days; choose healthy and pest-free sugarcane to cut off as cane seeds, wash the cane seeds and place them in the Soak in warm water at 50°C for 25 minutes, add fungicide to the warm water, take it out and drain, open a flat-bottomed sowing ditch in the planting ditch, and cover with soil after shallow sowing;

[0051]2) Fertilization management: apply basal fertilizer in the planting ditch before sowing, and the basal fertilizer includes nitrogen, phosphorus, potassium, silicon, calcium and magnesium fertilizers; in the tillering stage of sugarcane, carry out the first topdressing, and the topdressing is spraying diluted potassium dihydrogen phosphate on the leaves; During the jointing stage of sugarcane, the second topdressing is carried out, and t...

Embodiment 1

[0077] Embodiment 1 Newly planted sugarcane smut incidence rate 1.9% in the first year, adding the sugarcane strain number pulled out because of smut is 8.5% in total, output is 6.7t / mu, sugarcane (the 1st year perennial root) smut in the second year Disease incidence rate 2.1%, add the sugarcane strain number that pulls out because of smut and add up to 3.9%, output is 6.0t / mu, the 3rd year sugarcane (the 2nd year perennial root) smut sickness rate 0.5%, add the sugarcane strain number that is pulled out because of smut A total of 1.8% of the sugarcane strains were pulled out, the yield was 5.5t / mu, and the three-year average yield was 6.07t / mu;

Embodiment 2

[0078] Embodiment 2 In the first year, the newly planted sugarcane smut incidence rate is 2.1%, and the sugarcane strain number pulled out because of smut is 9.1% in total, and the output is 6.6t / mu. In the second year, sugarcane (perennial root) smut Disease incidence rate 2.5%, add the sugarcane strain number that pulls out because of smut and add up to 4.1%, output is 5.5t / mu, the 3rd year sugarcane (the 2nd year perennial root) smut sickness rate is 0.7%, adds because of smut The total number of sugarcane plants pulled out by disease is 2.0%, the yield is 5.1t / mu, and the three-year average yield is 5.73t / mu;

Abstract

The invention belongs to the field of crop planting, and discloses a planting method for preventing and controlling the sugarcane smut, which comprises the following steps: 1) scattering quicklime in planting furrows, covering with a mulching film, and then sowing; sterilizing sugarcane seed stem sections, performing shallow sowing in the planting furrows, and performing soil covering; 2) applying a base fertilizer in the planting furrows before sowing, wherein the base fertilizer comprises a nitrogen-phosphorus-potassium fertilizer and a silicon-calcium-magnesium fertilizer; carrying out primary topdressing in the tillering stage of the sugarcane; carrying out secondary topdressing in the elongation stage of sugarcane, and applying a nitrogen-potassium fertilizer; 3) after the newly planted sugarcane is planted for 2 months and the seedlings grow to the same height as the stubble cane, starting regular inspection, pulling out smut plants during inspection, taking the smut plants out of the field and burning the smut plants in a centralized manner, and leaving no biennial root of the sick plants in the sick field. By means of the method, smut prevention and control are conducted in the whole planting process, the morbidity of smut can be effectively reduced, and the yield of sugarcane is remarkably increased.
