[0034] Table 4 Comparison of input and output between ratoon cane fertilization of molasses alcoholic fermentation broth and conventional fertilization

[0035]

[0036] It can be seen from Table 3 and Table 4 that the newly planted sugarcane was applied with 75t / hm 2 Compared with the conventional fertilization treatment, the alcoholic fermentation liquid increased the income by 5006.25 yuan, and the treatment with 105 tons of alcoholic fermentation liquid per hectare of cane root cane had the best benefit. Applying 105 tons of alco...

Embodiment 2

[0038] The field management of each treatment in this test is basically the same, the Baume degree of the molasses alcohol fermentation liquid is 6-8, and the dosage is 75t / hm 2 ; The economic benefits only carry out the cost comparison of applying molasses alcohol fermentation liquid and conventional fertilizer application; the results of newly planted cane and perennial root cane are listed in Table 5 and Table 6 respectively.

[0044] It can be seen from Table 5 and Table 6 that the newly planted sugarcane was applied at 75t / hm 2Compared with the conventional fertilization treatment, the molasses alcohol fermentation liquid n...

Embodiment 3

[0046] The field management of each treatment in this experiment is basically the same, the Baume degree of the molasses alcohol fermentation liquid is 6-8, and the dosage is 45t / hm 2 , the economic benefit is only compared with the cost of applying molasses alcohol fermentation liquid and conventional chemical fertilizers. The results of newly planted cane and perennial root cane are listed in Table 7 and Table 8, respectively.

Abstract

The invention discloses a method for using sugar-syrup alcohol fermentation liquid as a sugarcane liquid fertilizer. To apply the sugarcane liquid fertilizer to newly planted cane plants, the method comprises the following steps: diluting the fermentation liquid till the Baume degree reaches 6 to 8 and spraying the sugarcane liquid fertilizer in furrows for planting cane at a rate of 90 to 110 tons per hectare after the cane seeds are planted; covering a film on the next day after spraying operation and spraying pre-emergence herbicide; and removing the film after the stem pushing of cane seedlings and carrying out cultivating and hilling without applying any chemical fertilizer. To apply the sugarcane liquid fertilizer to stubble cane, the method comprises a step of diluting the fermentation liquid till the Baume degree reaches 8 to 10 and other steps which are the same as those used for newly planted cane plants. Using sugar-syrup alcohol fermentation liquid as a sugarcane fertilizer, the method solves the problem of pollution caused by sugar-syrup alcohol fermentation liquid of a sugar refinery and the problem of sugar liquid manure, recycles waste materials, increases soil fertility and improves production and yield of sugar. When applied at a rate of 45 to 105 t / hm<2>, a stock solution of the fermentation liquid can increase yield of sugar by 10 to 30 percent compared with the prior chemical fertilizer applied.

Description

technical field [0001] The invention relates to a method for using molasses alcohol fermentation liquid as sugarcane liquid fertilizer. Background technique [0002] Guangxi is the largest sugar industry base in my country, and the sucrose industry is also an important economic pillar in Guangxi. Cane sugar production accounts for about 70% of the country's total. Fermentation of molasses, a by-product of sugar production, to produce alcohol, lysine, and yeast is an important way for comprehensive utilization of sugarcane. However, due to the technical solutions for comprehensive utilization have not been well resolved, most of the molasses fermentation liquid has long been regarded as The discharge of waste liquid not only fails to make good use of this resource, but also causes serious environmental pollution. [0003] The ingredients in the molasses fermentation liquid are mainly the nutrients absorbed by the sugarcane from the soil and the organic substances synthesized...
