Fertilizing method for bio-organic fertilizer utilizing waste produced during processing of fuel ethanol

Abstract

The invention provides a fertilizing method for a bio-organic fertilizer which utilizes waste produced during processing of fuel ethanol. The fertilizing method comprises the following steps: acquisition of the bio-organic fertilizer: fermenting cassava lees generated in the alcohol production process and having undergone fermentation, and adding strains into the fermented cassava lees; S2, application of the bio-organic fertilizer: applying the bio-organic fertilizer obtained in S1 as a base fertilizer into soil; and S3, topdressing of water and fertilizer: in the later period of crop growth,and spraying the water and fertilizer as topdressing fertilizer on crop leaves by using a foliar fertilizer application method once every 5-7 days, wherein the spraying is performed three times in total. The method provided by the invention not only can meet the requirements of crops on nutrition, but also does not destroy the soil structure, and can reduce diseases and insect pests. The used bio-organic fertilizer is originated from a pure plant source, is high in organic matter content, thorough in fermentation due to quadruple fermentation, free of pathogenic bacteria and capable of reducing the morbidity of crops, and does not burn seedlings; and the used water and fertilizer is originated from a pure plant source, and is prepared by taking biological humic acid as a raw material through reasonable proportioning, so the requirements of crops on nutrients can be met, and nutrient loss can be prevented.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a fertilization method using bio-organic fertilizer in fuel ethanol processing waste. Background technique [0002] At present, the fertilization method of agricultural planting generally adopts the fertilization method of compound fertilizer and farmyard manure, but due to the excessive application of chemical fertilizers, it is easy to cause problems such as soil structure damage and soil erosion; If it is not handled properly, it will cause heat generation due to fermentation, which will cause seedling burning; moreover, farmyard manure contains a large number of pathogenic bacteria, and applying it to the soil will affect and increase the risk of crop diseases. Under such circumstances, there is an urgent need to explore a fertilization method that can meet the nutritional needs of crops without destroying the soil structure and reducing pests and diseases.
