Embodiment 1

[0021] The production process of converting cassava waste into organic fertilizer includes the following steps:

[0022] (1) Build a large slope on a 2-5 degree cement floor storage yard, build a shallow cement ditch around the floor, and set up a waste water recovery pool at a corner of the site to seep down from the stacked cassava waste The waste water in the pool flows into the recycling pond, and the waste water in the pond can be used to adjust the humidity of cassava waste stems, branches and leaves during fermentation.

[0023] (2) The discarded stalks and branches of cassava are pre-crushed with a straw crusher into a cross-sectional area of ​​0.3cm 2 the following shreds;

[0024] (3) Spread the broken cassava waste materials on the fermentation field to build a heap, put a layer of 500kg waste materials, the height of the material on the first layer is 10cm, and evenly sprinkle a layer of 10kg urea, 5kg superphosphate and 0.25kg on the material Put a layer of 500k...

Embodiment 2

[0027] (1) Build a large slope on a 2-5 degree cement floor storage yard, build a shallow cement ditch around the floor, and set up a waste water recovery pool at a corner of the site to seep down from the stacked cassava waste The waste water in the pool flows into the recycling pond, and the waste water in the pond can be used to adjust the humidity of cassava waste stems, branches and leaves during fermentation.

[0028] (2) The discarded stalks and branches of cassava are pre-crushed with a straw crusher into a cross-sectional area of ​​0.3cm 2 the following shreds;

[0029] (3) Spread the broken cassava waste materials on the fermentation field to build a heap, put a layer of 500kg waste materials, the height of the material on the first layer is 12cm, and evenly sprinkle a layer of 10kg urea, 15kg superphosphate and 0.15kg on the material Candida utilis, on top of it, put a layer of 500kg of waste materials, and then sprinkle a layer of 10kg of urea, 15kg of superphosph...

Embodiment 3

[0032] (1) Build a large slope on a 2-5 degree cement floor storage yard, build a shallow cement ditch around the floor, and set up a waste water recovery pool at a corner of the site to seep down from the stacked cassava waste The waste water in the pool flows into the recycling pond, and the waste water in the pond can be used to adjust the humidity of cassava waste stems, branches and leaves during fermentation.

[0033] (2) The discarded stalks and branches of cassava are pre-crushed with a straw crusher into a cross-sectional area of ​​0.3cm 2 the following shreds;

[0034](3) Put the crushed cassava waste materials on the fermentation field to mix and build a heap, put a layer of 500kg waste materials, the material height of one layer is 10cm, and evenly sprinkle a layer of 10kg urea and 10kg superphosphate to neutralize 0.35 kg Candida tropicalis, on it, put a layer of 500kg waste materials, and then sprinkle a layer of 10kg urea, 10kg superphosphate and 0.35kg Candida...

Abstract

The invention discloses a production process for converting cassava wastes into organic fertilizers, comprising the following steps: (1) precrushing waste stems, branches and leaves of cassava; (2) adding inorganic nitrogenous and phosphorus fertilizers and yeast into the waste materials for pile-fermentation, and then mechanically turning over piles and drying till the water content of the wastematerials is between 10 percent to 20 percent; and (3) conveying the dried fermented waste materials into a mixer, mixing the dried fermented waste materials with nitrogen, phosphorus and potassium fertilizers, and then pulverizing, pelletizing by extrusion, drying in a drum and packaging to obtain finished products. Because waste stems, branches and leaves after cassava reaping are processed into organic fertilizers, the waste materials are fully utilized and changed into valuables, and the problem of the environmental pollution of the waste materials is also solved.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer production, and particularly refers to a production process for converting discarded stems, branches and leaves of cassava after harvesting into high-quality organic fertilizers. Background technique [0002] In recent years, my country's cassava industry has developed rapidly and has become an important part of the crop industry in tropical regions. In 2005, the national cassava planting area was 6.57 million mu, the total output of fresh potato was more than 7 million tons, and the total output value was nearly 3 billion yuan. [0003] 90% of the country's cassava production is concentrated in Guangdong and Guangxi, and the industrial layout has initially formed. At present, in the key areas of cassava development, such as Wuming, Chongzuo, Pingguo, Binyang and other counties in Guangxi, cassava production has already The planting of improved varieties, the standardization of high-yi...
