Embodiment 1
[0033] A new type of water-retaining fertilizer of the present embodiment is made from the following raw materials: 30kg of fermented mushroom dregs, 7kg of potassium fulvic acid, 1kg of alginic acid, 2kg of pectin, 5kg of urea, 15kg of potassium nitrate and 3kg of microbial inoculum. The bacterial agent is a mixture of nitrogen-fixing bacteria, yeast and lactic acid bacteria, and the nitrogen-fixing bacteria contained in each gram of fertilizer is 2×10 8 cfu, 5 x 10 for yeast 8 cfu, lactic acid bacteria is 2×10 8 cfu.
[0034] The preparation method of the novel water-retaining fertilizer of the present embodiment comprises the steps:
[0035] (1) take by weighing respectively according to the weight of each raw material for subsequent use;
[0036] (2) After pulverizing urea and potassium nitrate respectively, mix them evenly with fermented mushroom slag and microbial inoculant. The particle size of the ground urea and potassium nitrate is 0.06 mm to obtain a mixture, and...

[0039] A new type of water-retaining fertilizer of the present embodiment is made from the following raw materials: 35kg of fermented mushroom dregs, 5.5kg of potassium fulvic acid, 1.5kg of alginic acid, 1.5kg of pectin, 7.5kg of urea, 12.5kg of potassium nitrate and microbial inoculum 4kg, wherein the microbial agent is a mixture of nitrogen-fixing bacteria, yeast and lactic acid bacteria, and the nitrogen-fixing bacteria contained in each gram of fertilizer is 2.5×10 8 cfu, 4 x 10 for yeast 8 cfu, 3×10 for lactic acid bacteria 8 cfu.
[0040] The preparation method of the novel water-retaining fertilizer of the present embodiment comprises the steps:
[0041] (1) take by weighing respectively according to the weight of each raw material for subsequent use;
[0042] (2) After pulverizing urea and potassium nitrate respectively, mix them evenly with fermented mushroom slag and microbial inoculant. The particle size of urea and potassium nitrate is 0.08mm to obtain a mixtur...
Embodiment 3
[0045] A new type of water-retaining fertilizer in this embodiment is made from the following raw materials: 40kg of fermented mushroom dregs, 4kg of potassium fulvic acid, 2kg of alginic acid, 1kg of pectin, 10kg of urea, 10kg of potassium nitrate, and 35kg of microbial inoculum. The bacterial agent is a mixture of nitrogen-fixing bacteria, yeast and lactic acid bacteria, and the nitrogen-fixing bacteria contained in each gram of fertilizer is 3×10 8 cfu, 3 x 10 for yeast 8 cfu, 4×10 for lactic acid bacteria 8cfu.
[0046] The preparation method of the novel water-retaining fertilizer of the present embodiment comprises the steps:
[0047] (1) take by weighing respectively according to the weight of each raw material for subsequent use;
[0048] (2) After pulverizing urea and potassium nitrate respectively, mix them evenly with fermented mushroom slag and microbial inoculant, the particle diameter of urea and potassium nitrate is 0.10mm to obtain a mixture, and potassium f...
