Problems solved by technology

[0003] The common cultivation substrates in my country's existing facility agriculture are mainly made of peat, vermiculite, perlite, etc., among which peat is one of the best soilless cultivation substrates recognized so far, but peat is a non-renewable resource. The price is also increasing day by day, long-term mining use will cause resource depletion
There are many organic cultivation substrates using non-renewable resources as raw materials in the prior art, but some of them cannot be popularized in large quantities due to geographical distribution, transportation costs and production limitations.

Abstract

The invention provides an organic culture medium applicable to bare place facilities of coastal mud flats. The organic culture medium comprises the following raw materials: plant wastes, organic fertilizers and rice husk carbon. The organic culture medium is prepared by flattening and crushing plant wastes by using a crushing machine, adding the organic fertilizers to adjust the ratio of carbon tonitrogen, adjusting the water content, adding microorganism composted composite bacterial agents and chitosan, uniformly stirring by using a pile turning machine, forming a conical pile, turning andmixing by using the pile turning machine every other 2-4 days, composting for 10-18 days till the mixture is brown or black brown, free of smell and soft and elastic when being held by hand and the ratio of carbon to nitrogen is reduced, and the water content is reduced, so as to obtain a composted mixture after composting is completed, and by mixing the composted mixture and the completely carbonized rich husk carbon according to a ratio. The medium is rich in raw material source, agricultural wastes are sufficiently utilized, the production cost is reduced, the purposes of environment protection and regeneration are achieved, local production of cultivation mediums in coastal mud flats is achieved, and the transportation cost is reduced.

Description

technical field [0001] The invention relates to the field of agricultural facility cultivation, in particular to an organic cultivation substrate suitable for coastal non-arable land facilities. Background technique [0002] The non-cultivated land area of ​​coastal tidal flats in Jiangsu Province is 5,100 km2, accounting for 24% of the national tidal flats. The development and utilization of saline-alkali non-cultivated land facilities in coastal tidal flats can solve the conflict between economic crops and food crops, so it can improve the efficiency of land resources in non-cultivated areas of our province. Utilizing and improving crop yield and quality in non-cultivated areas of coastal tidal flats can not only realize the coordinated development of efficient ecological agriculture but also promote the establishment of local ecological agricultural systems. [0003] The common cultivation substrates in my country's existing facility agriculture are mainly mixed with peat...
