Embodiment 1

[0020] A management method for perennial sugarcane comprises the following steps:

[0021] Step (1), set the position of the bottom knife of the shovel ridge breaking machine at 5-6cm higher than the top of the ridge, and then remove the sugarcane higher than the bottom knife, leave the cane pile 7-8cm high, and leave the cane pile at the base node There are 2-3 live buds;

[0022] Step (2), fertilize after shoveling, apply calcium 748kg / ha, urea 297kg / ha and potassium sulfate 298kg / ha, and apply dimehypo 90kg / ha at the same time;

[0023] Step (3), spray atrazine aqueous solution after fertilization, and finally cover with plastic film, the thickness of the plastic film is 0.008mm, and the width is 30mm;

[0024] The preparation method of the atrazine aqueous solution that adopts per hectare is 40% atrazine 3.75L mixes water 900kg, mixes evenly, obtains final product.

Embodiment 2

[0026] A management method for perennial sugarcane comprises the following steps:

[0027] Step (1), set the position of the bottom knife of the shovel ridge breaker 7-8cm higher than the top of the ridge, and then remove the sugarcane that is higher than the bottom knife, leaving the cane pile 9-10cm high, and the remaining cane pile base node There are 2-3 live buds;

[0028] Step (2), fertilize after shoveling, apply calcium 752kg / ha, urea 301kg / ha and potassium sulfate 302kg / ha, and apply dimehypo 75kg / ha at the same time;

[0029] Step (3), spray atrazine aqueous solution after fertilization, and finally cover with plastic film, the thickness of the plastic film is 0.008mm, and the width is 40mm;

[0030] The preparation method of the atrazine aqueous solution that adopts per hectare is 4.5L of 40% atrazine mixed with water 900kg, mix evenly, obtain final product.

Embodiment 3

[0032] A management method for perennial sugarcane comprises the following steps:

[0033] Step (1), set the position of the bottom knife of the shovel ridge breaking machine at 6-7cm higher than the top of the ridge, then remove the sugarcane higher than the bottom knife, leave the cane pile 8-9cm high, and leave the cane pile at the base node There are 2-3 live buds;

[0034] Step (2), fertilize after shoveling, apply calcium 750kg / ha, urea 300kg / ha and potassium sulfate 300kg / ha, and apply dimehypo 80kg / ha at the same time;

[0035] Step (3), spray atrazine aqueous solution after fertilization, and finally cover with plastic film, the thickness of the plastic film is 0.008mm, and the width is 35mm;

[0036] The preparation method of the atrazine aqueous solution that adopts per hectare is 40% atrazine 4L mixes water 900kg, mixes evenly, obtains final product.

Abstract

The invention relates to a management method of ratoon sugarcanes and belongs to the technical field of crop management. According to the management method, stubble shoveling, fertilizer application, solution spraying and film lamination steps are finished in sequence through utilizing a stubble shoveling and ridge breaking machine; the management method specifically comprises the following steps: setting the position of a bottom cutter of the stubble shoveling and ridge breaking machine to be 5cm-8cm higher than a ridge top; then shoveling off sugarcanes higher than the bottom cutter and remaining sugarcane piles to be 7cm-10cm, so as to increase the air permeability of soil and reduce diseases and insects; applying fertilizers after shoveling stubbles, and applying 748kg / ha-752kg / ha of single superphosphate, 297kg / ha-301kg / ha of urea and 298kg / ha-302kg / ha of potassium sulfate; meanwhile, applying 75kg / ha-90kg / ha of bisultap; after applying the fertilizers, spraying an atrazine water solution; and finally, covering a mulching film. According to the management method provided by the invention, the air permeability of the soil is easy to improve and the oxygen content of the soil is improved; the emergence rate and the tillering rate are improved; and meanwhile, the occurrence of plant diseases and insect pests can also be reduced and the yield of the sugarcanes is finally improved.

Description

technical field [0001] The invention belongs to the technical field of crop management, and in particular relates to a management method for perennial sugarcane. Background technique [0002] Sugarcane is a perennial plant. After the sugarcane is harvested in the previous season, it uses the lateral buds left in the soil and on the stalks to grow into a new plant, which is artificially cultivated to become a new season of sugarcane, called ratoon sugarcane. Rattle cane management is an important cultural system in sugarcane production. Perennial sugarcane has the obvious advantages of saving planting, saving labor, early maturity, facilitating labor arrangement and reducing production costs. However, at present, most of them are manual shoveling or mechanical shoveling, but the shoveling is not in place, and the effect cannot be achieved. Therefore, how to overcome the deficiencies in the prior art is an urgent problem to be solved in the field of crop management technolog...
