Abstract

The invention discloses a preparation method of organic fertilizer powder special for soilless culture through two-time fermentation. The preparation method comprises the steps that fresh marsh mud and wastewater produced by a sugar mill are evenly mixed, and standing is performed to obtain a first material; food waste, straw residues, livestock excrement, fruit residues, azoila imbricata, traditional Chinese medicine residues, powdered rock phosphate and a compound enzyme preparation are added into the first material and are mixed evenly, a PH value is regulated, and then anaerobic fermentation is performed to obtain a second material; the second material is subjected to filter pressing to obtain a third material; the third material, wormcast, urea, dipotassium phosphate, calcium chloride, humic acid and a compound bacterial preparation are mixed evenly, and then standing, concentration, drying and smashing are performed to obtain the organic fertilizer powder produced through two-time fermentation and special for soilless culture. The organic fertilizer powder is fully decomposed through two-time fermentation, contains rich organic matter and multiple nutrient elements and can meet the technical demand for soilless culture.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer powder preparation, in particular to a method for preparing organic fertilizer powder special for double-fermentation soilless cultivation. Background technique [0002] Soilless cultivation refers to the agricultural technology that does not use natural soil but uses substrates for cultivation. Soilless cultivation is suitable for large-scale production and is not limited by land conditions. It can make crops grow rapidly and meet the needs of high-quality agricultural products and economic crops such as vegetables and fruits. , flowers and other planting needs. In the prior art, nutrient solution is often used to supplement the loss of matrix nutrients in the process of soilless cultivation. This method has high cost, incomplete nutrient content and cannot effectively supplement the loss of organic matter in the matrix, thus restricting the further development of soilless cultivation ...
