A system for producing multiple water-soluble organic carbon fertilizers using vegetable waste

Abstract

The present invention relates to a system using vegetable waste for production of a multi-component water soluble organic carbon fertilizer, the system includes a slag liquid separation system and a fermentation preparation system; the slag liquid separation system is provided with a liquid outlet, and the liquid outlet is connected with a liquid inlet of the fermentation preparation system. The slag liquid separation system comprises a juice collection bucket with the liquid outlet, a filter sieve and a pressing screw; the filter sieve is installed at the upper opening end of the juice collection bucket, and the screw pitch of the pressing screw located above the filter sieve is gradually reduced from a feeding port to a slag discharge port of the slag liquid separation system. The fermentation preparation system comprises a liner, a temperature control jacket for sleeving the liner, a stirrer, a mixer, and a sterile air filter in connection with the liner. The system can cleanly use the vegetable waste, can convert the vegetable waste into the fertilizer, has the characteristics of being high in degree of cleaning, thorough in killing of pathogenic bacteria, environmentally-friendly, and pollution-free, and belongs to the technical field of agricultural waste recycling and environmentally-friendly devices.

Description

technical field [0001] The invention relates to the technical field of resource utilization of agricultural waste and environmental protection devices, in particular to a system for producing multiple water-soluble organic carbon fertilizers by using vegetable waste. Background technique [0002] After years of rapid development, China's vegetable industry has made remarkable achievements in many aspects such as variety selection, increased and stable production, and quality and safety. It has developed into the world's largest vegetable market, which greatly meets and enriches the material needs of urban and rural residents for vegetables. . Moreover, with the completion of the national planning and layout of the vegetable industry, the national vegetable planting area and output are also rising. Its planting area increased from 262 million mu in 2007 to 313 million mu in 2013, and its output increased from 547 million tons in 2007 to 706 million tons in 2013. It has surpa...

Problems solved by technology

For a long time, under the condition that the amount of nitrogen, phosphorus and potassium fertilizers has been greatly increased, the supplement of carbon nutrition has not been considered. The carbon nutrition obtained by crops relying on the natural state can only meet 1 / 5 of their needs, and the crops are far from carbon starvation. Serious It restricts the improvement of crop yield potential, and carbon starvation can be eliminated by adjusting fertilization and carbon supplementation and optimizing plant nutrition balance
