Problems solved by technology

Although this soilless cultivation method is simple, there are still problems such as defertilization in the late growth period and unstable yield in practical application; and the sources of raw materials used to ferment organic substrates in various places are complicated, the degree of fermentation varies greatly, the quality of substrates is unstable, and the cultivation The effect is not obvious; during the cultivation process, fertilizer needs to be continuously replenished, which is inconvenient to operate and cannot be quantified

Embodiment Construction

[0013] The present invention will be further described below in conjunction with a specific embodiment.

[0014] An organic slow-release fertilizer for soilless cultivation, consisting of 40% pure dry chicken manure, 40% cottonseed cake, 5% potassium humate, 5% bran, 5% phosphate rock powder, and 5% mineral potassium fertilizer , and mixed with a mixed bacterial solution composed of photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, phosphate-solubilizing bacteria and potassium-solubilizing bacteria.

[0015] First air-dry the chicken manure to make the water content 25-30%, then mix and coarsely grind the dried chicken manure, cottonseed cake, potassium humate fertilizer, phosphate rock powder, mineral potassium fertilizer and bran in proportion, mix them thoroughly and put them into fermentation In the pool, insert mixed strains to make the water content of the material about 50%, and ferment at room temperature for 3 days. After the fermentation, the ferm...

Abstract

The organic slow-release fertilizer for soil-less culture is produced with dry chicken manure and compounded cake fertilizer, humic fertilizer, bran, ground phosphate rock and mineral potassium fertilizer, and through mixing, crushing, mixing with water, inoculating bacteria strain, fermentation at normal temperature, stoving at low temperature, pelletizing and coating with release controlling coating agent. Before pelletizing, chemical fertilizer may be added. The present invention utilizes the leftover from agricultural product processing and mixes various fertilizer with different acting period into the medium for soil-less culture. The fertilizer can meet the requirement of producing green food.

Description

Technical field: [0001] The invention relates to an organic slow-release fertilizer, in particular to an organic slow-release fertilizer for soilless cultivation and a processing technology thereof, which is used for producing organic vegetables, green vegetables or cultivated flowers, etc., and belongs to the field of agricultural technology. Background technique: [0002] At present, soilless cultivation technology has been widely used. There are many forms of soilless cultivation. In my country, substrate cultivation is the main method. The commonly used method is to irrigate with organic or inorganic substrate and nutrient solution prepared by inorganic fertilizer. With the improvement of people's living standards and the aggravation of the pollution of vegetable fertilizers and pesticides, the demand for green vegetables and food is increasing rapidly, and vegetables grown in nutrient solution cannot be included in organic or green food, and the nutrient solution cultiva...
