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...

Abstract

The invention relates to a novel water-retaining fertilizer and a preparation method thereof. The novel water-retaining fertilizer is prepared from fermented mushroom residues, potassium fulvate, alginic acid, pectin, urea, potassium nitrate and a microbial agent. The water-retaining fertilizer takes the fermented mushroom residues, the potassium fulvate, the urea and the potassium nitrate as mainraw materials, are fermented through the microbial agent, and are compatible with the alginic acid and pectin to be decomposed into a small molecular fertilizer containing organic matters, and the small molecular fertilizer can be combined with soil colloid, so the soil structure is improved, and the water retention capacity of the soil is increased; the alginic acid can further adjust the pH value of the soil. The fertilizers formed through the synergistic effect of the raw materials have good water retention property, and can bind the soil into the stable aggregate structure so as to loosenthe soil and effectively improve the soil; and the preparation method of the water-retaining fertilizer is simple, the loss rate is low, the prepared particles are uniform, the strength is better, the production cost is low, and large-scale production can be realized.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a novel water-retaining fertilizer and a preparation method thereof. Background technique [0002] Drought is the first disaster that endangers agricultural and animal husbandry production. Meteorological conditions affect the distribution, growth and development, yield and quality of crops, while water conditions are the main conditions that determine the type of agricultural development. Drought has become the most serious meteorological disaster affecting agricultural production in my country due to its high frequency of occurrence, long duration, wide range of influence, and large delay. [0003] With the rapid development of the economy and society, the shortage of water resources has become a "bottleneck" restricting the development of agriculture. The problems of food security and ecological environment security have become increasingly prominent, and the s...
