Problems solved by technology

The yield of ratoon cane is related to the management of rattan cane. Unreasonable management of rattan cane can easily lead to problems such as thin cane stems, few plants, slow tillering, many missing plants, low stem formation rate, low yield per unit area, and short cane plants. Due to unreasonable management, the average per mu yield of sugarcane is far lower than that of newly planted cane, and in serious cases, there may even be no harvest. Therefore, providing a good management method for rattan cane is of great significance for ensuring the harvest of sugarcane and even increasing the income of sugarcane planting pivotal role

Embodiment 1

[0027] (1) After harvesting the sugarcane, clean up the weeds and cane shoots in the sugarcane field, recycle the sugarcane straw, and crush the sugarcane straw to form a grass section with a length of less than 20cm;

[0028] (2) Spray the aqueous solution formed by mixing urea, zinc nitrate and water onto the crushed sugarcane stalks so that the water content of the stalks reaches 60-70%. Then put several wooden pillars horizontally above the straw layer. The length of the wooden pillars exceeds the width of the straw layer by 5~10cm, and the distance between the wooden pillars is 80~100cm. Stacks with 5 layers of straw, piles fermented for 9 days, took out the wooden pillars and continued to ferment for 30 days to obtain organic fertilizer from decomposed sugarcane straw; the amount of urea was 0.5% of the dry weight of the straw, and the amount of zinc nitrate was 1% of the dry weight of the straw. The dosage of the bacterial agent is 0.2% of the dry weight of the straw, a...

Embodiment 2

[0033] (1) After harvesting the sugarcane, clean up the weeds and cane shoots in the sugarcane field, recycle the sugarcane straw, and crush the sugarcane straw to form a grass section with a length of less than 20cm;

[0034](2) Spray the aqueous solution formed by mixing urea, zinc nitrate and water onto the crushed sugarcane stalks so that the water content of the stalks reaches 60-70%, and then spread the stalks into a 30-40cm straw layer in the sugarcane field fermentation field, sprinkle the mixed Then put several wooden pillars horizontally above the straw layer. The length of the wooden pillars exceeds the width of the straw layer by 5~10cm, and the distance between the wooden pillars is 80~100cm. 4-layer straw stacks, the stacks were fermented for 8 days, and the wooden pillars were taken out to continue fermentation for 25 days to obtain the decomposed organic fertilizer of sugarcane straw; the amount of urea was 0.2% of the dry weight of the straw, and the amount of ...

Embodiment 3

[0039] (1) After harvesting the sugarcane, clean up the weeds and cane shoots in the sugarcane field, recycle the sugarcane straw, and crush the sugarcane straw to form a grass section with a length of less than 20cm;

[0040] (2) Spray the aqueous solution formed by mixing urea, zinc nitrate and water onto the crushed sugarcane straw so that the water content of the straw reaches 60-70%, and then spread the straw in a 30-40cm layer of straw in the fermentation field of the sugarcane field, and sprinkle the mixed bacteria Then put several wooden pillars horizontally above the straw layer. The length of the wooden pillars exceeds the width of the straw layer by 5-10cm, and the distance between the wooden pillars is 80-100cm. Straw layer stacks, piles fermented for 9 days, took out wooden pillars and continued to ferment for 28 days to obtain decomposed sugarcane straw organic fertilizer; the amount of urea was 0.4% of the dry weight of the straw, and the amount of zinc nitrate w...

Abstract

The invention relates to the technical field of agricultural planting, and particularly discloses a method for managing ratoon sugarcanes through field fermentation of sugarcane stalks, which mainly comprises the following steps: (1) after cutting sugarcanes, recovering the sugarcane stalks, and crushing the sugarcane stalks; (2) pretreating the straws by using urea and zinc nitrate, and then fermenting the straws in a sugarcane field to obtain a sugarcane straw decomposed organic fertilizer; (3) after stump shoveling treatment, mixing a sugarcane straw decomposed organic fertilizer and a sugarcane medical fertilizer, scattering the mixture around the sugarcane stump, and covering soil; (4) fully covering the ratoon sugarcane stumps by using a mulching film; 5, film uncovering is conducted in time from April to May, irrigation is conducted after seedlings are aligned, seedling fertilizer is applied, small hilling is conducted, and grass sealing is conducted; applying a stem-attacking fertilizer in a jointing growth period, deinsecting, carrying out large-scale ridging and sealing grass; tail strengthening fertilizer is applied in late August. The method for managing the ratoon sugarcanes is beneficial to improving the emergence rate of the ratoon sugarcanes, increasing the yield and sucrose content of the sugarcanes, and realizing on-site effective utilization of straws after harvesting the sugarcanes.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for managing perennial root cane by utilizing sugarcane straw in field fermentation. Background technique [0002] Perennial root cane refers to the sugarcane strain formed by the re-germination and growth of the buds of the cane stalks left in the sugarcane field after the sugarcane was cut and harvested in the previous year under suitable conditions such as temperature, fertility supply, and humidity. Perennial root cane has the advantages of high sugar content, time-saving management, cane seed saving, early maturity, etc., and accounts for the main part of the cane planting area. The yield of ratoon cane is related to the management of rattan cane. Unreasonable management of rattan cane can easily lead to problems such as thin cane stems, few plants, slow tillering, many missing plants, low stem formation rate, low yield per unit area, and s...
