Problems solved by technology

[0004] Traditional perennial sugarcane management includes: after the sugarcane is harvested, timely dispose of the green leaves and dead leaves and stems left on the sugarcane field; The growth has a greater impact, and the sugarcane fields that are harvested in winter or early spring and stay in the perennial roots often cause dead bushes or less cane seedlings due to drought.
Moreover, due to improper management of rattan cane, it is easy to cause yellowing disease, thereby reducing the yield and quality of sugarcane

Embodiment 1

[0023] The test base of this example is located in Jiangzhou District, Chongzuo City, Guangxi. The sugarcane variety is Guitang No. 42, which is a 2-year-old perennial root cane.

[0024] A method for managing perennial root cane in sugarcane yellowing disease-prone areas, comprising the steps of:

[0025] (1) After the newly planted sugarcane of last year is adopted, the sugarcane leaves are crushed and returned to the field for processing;

[0026] (2) In mid-February, after breaking the ridge before the emergence of the perennial cane, spread the soil conditioner with the amount of 1000kg / mu; 460 parts of charcoal and 1.0 part of repairing agent. The mass ratio of Bacillus megaterium, Bacillus amyloliquefaciens, Bacillus licheniformis and Trichoderma viride in the repairing bacteria agent is 6:3:5:1, and the number of effective viable bacteria is more than or equal to 500 million / g.

[0027] (3) Spray sugarcane foliar fertilizer (diluted 1500 times with water) every other...

Embodiment 2

[0046] The test base of this example is located in Jiangzhou District, Chongzuo City, Guangxi. The sugarcane variety is Guitang No. 42, which is a 3-year-old perennial root cane.

[0047] A method for managing perennial root cane in sugarcane yellowing disease-prone areas, comprising the steps of:

[0048] (1) After adopting the newly planted sugarcane of the previous year at the end of January, the sugarcane leaves are crushed and returned to the field for processing;

[0049] (2) In the first ten days of February, after breaking the ridge before the emergence of the perennial cane, spread the soil conditioner with the consumption of 850kg / mu; 400 parts of charcoal and 1.5 parts of repairing bacteria agent. The mass ratio of Bacillus megaterium, Bacillus amyloliquefaciens, Bacillus licheniformis and Trichoderma viride in the restoration agent is 7:4:6:3, and the number of effective viable bacteria is more than or equal to 500 million / g.

Embodiment 3

[0054] The test base of this example is located in Fusui County, Chongzuo City, Guangxi. The sugarcane variety is Guitang No. 44, which is a 2-year-old perennial root cane.

[0055] A method for managing perennial root cane in sugarcane yellowing disease-prone areas, comprising the steps of:

[0056] (1) After the newly planted sugarcane of last year is adopted, the sugarcane leaves are crushed and returned to the field for processing;

[0057] (2) In mid-February, after breaking the ridge before the emergence of the perennial cane, sprinkle the soil conditioner with the amount of 900kg / mu; the soil conditioner consists of 10 parts of ferrous sulfate, 30 parts of hydrated lime, 400 parts of sugar factory coal ash, biological 500 parts of charcoal and 0.8 parts of repair bacteria agent. The mass ratio of Bacillus megaterium, Bacillus amyloliquefaciens, Bacillus licheniformis and Trichoderma viride in the restoration agent is 10:4:3:2, and the number of effective viable bacteri...

Abstract

The invention relates to the technical field of sugarcane planting, in particular to a perennial root sugarcane management method for a sugarcane yellowing susceptible area. According to the method, the soil conditioner is spread before seedling emergence of the ratoon sugarcane, sufficient nutrients are provided for the ratoon sugarcane, rooting and germination are promoted, chlorophyll is promoted, the pH value of soil is adjusted, residual pesticide in the soil is degraded, some heavy metal is transferred, solidified and passivated, and harmful soil residues are reduced; the effect of preventing and treating diseases and pests is achieved, flora balance is adjusted, and the condition of soil hardening is prevented and treated; the foliar fertilizer is sprayed after sugarcane seedling emergence, nutrients can be provided for ratoon sugarcane, growth of chlorophyll is promoted, root development can be promoted, the soil holding capacity and nutrient absorption capacity of sugarcane roots can be improved, the effects of yellowing resistance, seedling strengthening, drought resistance and high stress resistance are achieved, and an effective way is provided for high quality and high yield of ratoon sugarcane.

Description

technical field [0001] The invention relates to the technical field of sugarcane planting, in particular to a method for managing perennial root cane in areas prone to sugarcane yellowing. Background technique [0002] Sugarcane is a temperate and tropical crop and an important sugar economic crop in southern my country. It is widely planted in Guangxi, Guangdong and Fujian. During the planting process of sugarcane, pests and diseases will seriously hinder the growth of sugarcane. Among them, sugarcane yellowing disease is a worldwide sugarcane disease that seriously endangers the growth of sugarcane. Resulting in reduced sugarcane yield and poor quality of sugarcane. Therefore, how to prevent and control sugarcane yellowing has important research significance for improving sugarcane yield and quality. [0003] Sugarcane is a continuous cropping perennial crop. After the last stubble cane is harvested, the side buds left on the cane stalks in the soil germinate and grow un...
