Comparative example 1
1. The organic fertilizer prepared by mixing and fermenting the Maotai-flavor liquor vinasse and pit mud in the embodiment 2 is defined as CK; an organic fertilizer prepared from the following raw materials is defined as T: 80 parts of fresh vinasse, 10 parts of waste pit mud and 5 parts of waste straws (wherein the initial moisture content of the fresh vinasse is 55 percent, and the pH value is 4.0). The two materials adopt the same raw materials and scale, compost is carried out by adopting a fermentation tank mode of continuous feeding, bottom ventilation fermentation is carried out when the temperature is raised to be more than 65 ℃, and the contents of total nutrients, total nitrogen, total phosphorus and total potassium of the compost are compared after the compost is finished.
The result is shown in fig. 1, which illustrates that under the condition of keeping other conditions unchanged, the organic fertilizer with fertilizer efficiency (total nutrient is more than or equal to 5%) can be obtained without adding minerals, and after the minerals (total phosphorus) are added, the increase of other nutrients in the production process of the organic fertilizer can be further promoted.
Comparative example 2
1. The organic fertilizer prepared in the embodiment 3 of the invention is defined as CK2 treated, and the organic fertilizer prepared from the following raw materials is defined as T2: 71 parts of fresh vinasse, 15 parts of waste pit mud, 10 parts of waste straw and 4 parts of minerals (wherein the initial moisture of the fresh vinasse is 55 percent, and the pH value is 3.5). The two materials are composted by adopting the same raw materials and scale in a fermentation tank mode of continuous feeding, and bottom ventilation fermentation is carried out when the temperature is raised to above 65 ℃.
2. Test results for treatment CK2 versus treatment T2:
2.1 fermentation period
As can be seen from figure 2, the 4 th day of treating CK2 compost can reach 55 ℃ and last for 9 days above 55 ℃, can reach the compost harmless standard, and 17 days after one-time fermentation; the temperature of the treatment T2 is slowly increased, reaches above 55 ℃ in the 6 th day and continues for 9 days, and then the temperature starts to decrease until the end of primary fermentation and continues for 20 days; the results show that the change of the raw material components of the invention can meet the temperature requirement of primary fermentation of the organic fertilizer, but the fermentation period is relatively prolonged.
2.2 organic matter
As can be seen from fig. 3, after the primary fermentation is finished, after the processed CK2 and T2 are subjected to secondary fermentation and decomposition, organic matters of the processed CK2 and T2 are detected, the content of the CK2 organic matters is obviously higher than that of T2, and although the content of the organic matters of the batch of T2 meets the NY525-2012 standard (the content of the organic matters is not less than 45%), the organic matters of the finally produced organic fertilizer may not reach the standard in consideration of factors such as errors existing between batches.
The above results show that the raw material components of the present invention must be in a certain range, and beyond the protection range of the present invention, there is a risk that the production cycle is prolonged and the organic matter content does not reach the standard.
All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
