Problems solved by technology

However, most rice processing enterprises do not have a reasonable and effective process for utilizing rice husks, and many rice husks are discarded as agricultural waste
According to statistics, the current comprehensive utilization rate of rice husk is less than 10%.
However, there are not many ways to use rice husks that can really be produced on a large scale, or the economic benefits are not significant and the value-added is not large, or there are still some problems in terms of craftsmanship, technology, quality, and environmental pollution.
This is not only a great waste of resources, but also causes huge economic losses, and also causes a lot of pollution to the environment.

Abstract

The invention discloses a method for producing a soil conditioner by using rice husks as a raw material. The soil conditioner comprises the following raw materials in parts by weight: 90 to 100 partsof rice husk charcoal powder, 5 to 10 parts of biological bacterium powder, 20 to 30 parts of wormcast, 15 to 30 parts of urea and 5 to 10 parts of manganese dioxide; and the rice husk charcoal powderis uniformly mixed with the biological bacterium powder, the urea and the manganese dioxide, a mixture is fermented for 1 to 2 days, then the mixture is uniformly mxed with the wormcast, and the obtained product is dried and granulated so as to obtain the soil conditioner. The soil conditioner produced by the method can improve sol properties, improve soil fertility, improve water seepage, waterretention and ventilation abilities, improve soil quality and improve crop yield.

Description

technical field [0001] The invention relates to the technical field of soil conditioners, in particular to a method for producing soil conditioners by using rice husks as raw materials. Background technique [0002] Soil is the most basic means of production for human beings and the material basis for human survival. Due to soil-forming factors and human factors, my country's land resources have caused many soil problems, such as erosion, poor texture, poor structure or arability, salinity, acidification, toxic substance pollution, soil compaction, excessive or insufficient soil moisture, low fertility or Nutrient imbalance, etc. Typically, these barrier soils are difficult to use, but in recent years amending them with soil conditioners has shown better results. [0003] Soil conditioner is a product made of agricultural water-retaining agent and natural peat rich in organic matter and humic acid or other organic matter as the main raw materials, supplemented by biological...
