Problems solved by technology

[0005] (1) There are phenomena such as low content of effective bacteria and excessive bacteria. Inappropriate amount of chemical fertilizers or other additives are added to biological fertilizers, so that the nitrogen, phosphorus, and potassium content of chemical fertilizers in fertilizers are too high, resulting in the death of effective bacteria and loss of biological fertilizer. effect;
[0006] (2) For the cultivation of sweet potatoes in saline-alkali land, the survival rate of sweet potatoes is low, the yield per mu is low, and the starch content of sweet potatoes is low;
[0007] (3) It is used for sweet potato planti

Abstract

The invention provides a biological organic fertilizer special for sweet potatoes .The organic fertilizer is prepared from potassium fulvate, peat, citric acid, blackstrap, Chinese medicine residues, organic calcium, cedrol, silicone rubber powder, guizotia abyssinica plants, vermiculite, oat extract, pseudomonas syringae and halophilic methane bacteria .The invention further provides a preparation method of the fertilizer .According to the prepared fertilizer, the number of effective living bacteria is 650-670 million cfu/g, the total nitrogen content is 4.5-4.6 wt%, the total phosphorus content is 2.5-2.8 wt%, the total potassium content is 2.0-2.3 wt%, the organic matter content (dry basis) is 46.7-48.3 wt%, the water content is 21.1-21.6 wt%, and the pH is 5.56-5.62 .The fertilizer is specially used for planting sweet potatoes in saline and alkaline land, the survival rate of sweet potatoes is as high as 98.9-99.7%, and the yield per mu is 3,250-3,390 kilograms.

Description

Technical field [0001] The invention relates to a special biological organic fertilizer for sweet potatoes and a preparation method thereof, and belongs to the technical field of organic fertilizers. Background technique [0002] Bio-organic fertilizer refers to a type of microbial fertilizer and organic compound that is composed of specific functional microorganisms and organic materials that are mainly sourced from animal and plant residues (such as livestock and poultry manure, crop stalks, etc.) through harmless treatment and decomposing. Fertilizer effect. Bio-organic fertilizer has complete nutrient elements; bio-organic fertilizer can promote the utilization of chemical fertilizers and improve fertilizer utilization; bio-organic fertilizer is completely decomposed, does not burn roots, and does not rot; bio-organic fertilizer decomposes at high temperature and kills most pathogens and insects Eggs, reduce the occurrence of pests and diseases; bio-organic fertilizer contai...
