Problems solved by technology

At present, there are more than 200 cassava processing factories in Guangxi, and the waste (cassava skin, starch and alcohol by-products, etc.) discharged by cassava processing enterprises is as high as one million tons every year. However, the waste utilization rate of cassava processing industry is very low. , most of which are directly discharged without treatment, resulting in a great waste of resources and serious pollution of the environment

Embodiment 1

[0031] (1) After mixing cassava skin, starch residue, chicken manure, and tung bran in a volume ratio of 4:3:2:1, add 2.0kg of microbial fermentation agent to every 1000kg of raw materials, and fully stir and mix;

[0032] (2) Use 15.0kg of urea to adjust the C / N mass ratio of 1000kg of fermented product in step (1) to 25:1, and carry out compost fermentation after thorough mixing; stack the mixed fermented product in the turning tank of the fermentation field , ferment according to the pile height of 0.8-1.0 meters and the width of 1.0 meters, and monitor the temperature and water content of the pile; during the fermentation process, the water content is controlled at 55%-65%; after the composting of the mixed fermented material begins, within 30 days, Every 3 to 5 days, use a tractor knife rake to turn the pile once. When the fermentation temperature rises to 60-70°C and maintains it for 48 hours, turn the pile. But when the temperature exceeds 70°C, turn the pile immediately...

Embodiment 2

[0035] (1) After mixing cassava skin, starch residue, chicken manure, and shell powder in a volume ratio of 5:2:2:1, add 2.0kg of microbial fermentation agent to every 1000kg of waste raw materials, and fully stir and mix;

[0036](2) Use 12.0kg of urea to adjust the C / N mass ratio of 1000kg of fermented product in step (1) to 30:1, and carry out compost fermentation after fully mixing; stack the mixed fermented product in the turning tank of the fermentation field , ferment according to the pile height of 0.8-1.0 meters and width of 1.0 meters, and monitor the temperature and water content of the pile; during the fermentation process, the water content is controlled at 55%-65%; after the composting of the mixed fermented material begins, within 30 days, Every 3 to 5 days, use a tractor knife rake to turn the pile once. When the fermentation temperature rises to 60-70°C and keeps for 48 hours, turn the pile. But when the temperature exceeds 70°C, turn the pile immediately. Be ...

Abstract

The invention discloses a method for producing a solanaceous vegetable seedling growing substrate by utilizing a salvaged material of cassava processing. Cassava peels and starch residues are used as main raw materials, chicken manure and seed tung tree bran or chicken manure and shell powder are used as auxiliary materials, and the excellent solanaceous vegetable seedling growing substrate is produced through fermentation. The substrate is light and loose, has the advantages of good permeability, good water holding and fertilizer retaining abilities, and balanced, scientific and reasonable nutrient supply, can meet the balance demand of solanaceous vegetable crop seedlings on nutrients during a whole growth period, and effectively improves the survival rate, the stress resistance and the growing seedling quality of the solanaceous vegetable growing seedlings. The method realizes harmless treatment and resource utilization of the salvaged material of cassava processing, avoids great waste of resources and serious pollution of the environment, provides a new way for comprehensive utilization of the agricultural salvaged material, reduces the substrate production cost, reduces excessive exploitation of peat resources, protects the natural environment, and has wide application value.

Description

technical field [0001] The invention belongs to the technical field of seedling-raising substrates for solanaceous vegetables, in particular to a method for producing seedling-raising substrates for solanaceous vegetables by using cassava processing waste. Background technique [0002] At present, peat, vermiculite, and perlite are the main substrates for raising seedlings of solanaceous vegetables. However, peat resources are scarce, and most of them are concentrated in the Northeast. It is also a resource controlled by the state, and random mining is no longer allowed. Therefore, if renewable and recyclable agricultural organic waste resources are used to replace non-renewable natural resources such as peat and rock wool, it will not only improve the utilization rate of organic waste, but also ensure the sustainable use of limited natural resources. , in line with the current development needs of low-carbon agriculture. [0003] It is a new development direction to use or...
