Problems solved by technology

Since this kind of organic fertilizer is insoluble in water, most of it can only be applied to the soil in the form of base fertilizer, and it cannot be used in subsequent topdressing or drip fertilization.
In addition, there are also water-soluble organic fertilizers on the market, but these water-soluble organic fertilizers are prepared from amino acids or biomass extracts as raw materials, the cost is high, and the utilization rate of biomass is low

preparation example Construction

[0028] A preparation method of carbon-based full-nutrient liquid water-soluble fertilizer comprises the following steps:

[0029] Step S001, crushing the organic material, the diameter of the crushed organic material is less than 2 cm;

[0030] Step S002, putting the pulverized organic material into the reaction kettle and adding potassium hydroxide for alkaline hydrolysis, and adjusting the pH of the mixed solution after alkaline hydrolysis to 6.5-7.5 to obtain an alkaline solution;

[0031] Step S003, adding α-amylase, cellulase, and papain to the alkaline hydrolysis solution for enzymolysis to obtain an enzymolysis solution;

[0032] Step S004, adding the enzymatic hydrolysis solution to Bacillus amyloliquefaciens and Bacillus subtilis for bacterial hydrolysis, and adjusting the pH of the mixed solution after bacterial hydrolysis to 6.5-7.5 to obtain a bacterial hydrolysis solution;

[0033] Step S005, adding ammonium polyphosphate, urea phosphate, potassium pyrophosphate,...

Embodiment 1

[0052] Taking "Cabernet Sauvignon" as the research object in the main wine grape producing area at the eastern foot of Helan Mountain in Ningxia, a field experiment on the efficiency of carbon-based full-nutrient liquid water-soluble fertilizer was carried out at Lilan Winery in Yinchuan, Ningxia. Planting in the north-south direction, the row length of the test plot is 50m, the row spacing is 3m, and the spacing between two plants is 0.6m. The shaping method adopts inclined racking.

[0053] The field experiment adopts a random block design, and sets three treatments: no fertilization, conventional fertilization, and carbon-based full-nutrient liquid water-soluble fertilizer. Through the analysis of the yield and quality indicators of wine grapes, it is hoped to determine the effect of carbon-based full-nutrient liquid water-soluble fertilizer on wine grape production.

Embodiment 2

[0065] The field experiment was carried out in the greenhouse of Ningxia University Experimental Farm with tomato "Fenda" as the indicator crop. The randomized block design was adopted in the field experiment, and three treatments were set up: no fertilization, conventional fertilization, and carbon-based full-nutrient liquid water-soluble fertilizer.

[0066] Treatment 1: No fertilization

[0067] Treatment 2: conventional fertilization, the optimum fertilization amount is: urea 750kg·hm -2 , ammonium dihydrogen phosphate 600kg·hm -2 , potassium sulfate 900kg·hm -2 .

[0068] Treatment 3: This plan, carbon-based full-nutrient liquid water-soluble fertilizer, the optimal application rate, 750kg·hm -2 .

Abstract

The invention provides a carbon-based full-nutrient liquid water-soluble fertilizer suitable for drip irrigation fertilization, which comprises the following components in percentage by mass: 25% of water-soluble biomass, 3% of nitrogen element, 2% of phosphorus pentoxide, 15% of potassium oxide and 0.05% of trace elements, and the trace elements comprise iron, manganese, copper, zinc and boron. The invention also provides a preparation method of the carbon-based full-nutrient liquid water-soluble fertilizer. The water-fertilizer integrated organic nutrient topdressing in the later period canbe realized, drippers cannot be blocked in the drip irrigation process, and the implementation of water-saving irrigation is facilitated. The carbon-based full-nutrient liquid water-soluble fertilizerdisclosed by the invention is rich in organic matters, can play a role in activating soil, and can improve the utilization rate of nutrient elements in alkaline soil. The carbon-based full-nutrient liquid water-soluble fertilizer also contains rich beneficial bacteria and enzyme preparations, and can promote the formation of soil aggregates, increase the content of soil powder particles, loosen the soil texture and promote the water and fertilizer exchange of crop root regions and the efficient absorption of root systems.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a carbon-based full-nutrient liquid water-soluble fertilizer and a preparation method thereof. Background technique [0002] In recent years, drip irrigation water-soluble fertilizer has gradually been recognized as a new type of fertilizer. The production of water-soluble fertilizer can materialize fertilization technology, improve fertilizer efficiency, reduce the frequency of fertilization, and save the cost of fertilization. Water-soluble fertilizers can produce balanced fertilizers, high-nitrogen fertilizers, high-potassium fertilizers, and high-phosphorus fertilizers according to different ratios of nitrogen, phosphorus, and potassium according to the fertilizer requirements of different crops, and at the same time add various medium and micronutrients that play a key role in the growth of different crops. In addition, the production of water-soluble fertilizer ...
