Problems solved by technology

[0003] Water-retaining agent is a high-molecular polymer with super-high water-absorbing and water-retaining capacity made of strong water-absorbing resin. Salt water, when there is a lack of water, it can slowly release water for the soil to absorb water, improve soil condition, and is a good soil humidity control agent; it can absorb and maintain fertilizer, improve the utilization rate of fertilizer and prevent fertilizer loss; at the same time, it can use The soil forms an aggregate structure, improving the soil to provide a good environment for plant growth, etc., but most of the current water-retaining agents have a single function, only have the function of water retention and drought resistance, and cannot improve the soil

Embodiment 1

[0022] Put 50Kg of hot water (60℃) in a biological breeding tank, then add 3Kg of Span 20, stir and disperse evenly, add 15Kg of potassium aluminum sulfate dodecahydrate, 20Kg of urea, 45Kg of potassium dihydrogen phosphate, and stir well to make The lysate is dissolved and dispersed uniformly, and then 2Kg of natto bacteria are added, stirred evenly, and placed for 8 hours for fermentation and reproduction, and then natto bacteria liquid is obtained.

[0023] Put 1000Kg of soil water-retaining agent into the mixer, start the mixer to slowly spray the above-mentioned natto bacteria liquid, after spraying, continue to stir evenly and balance, and dehydrate to moisture content ≤ 8%, namely the soil biological enzyme water-retaining agent.

Embodiment 2

[0025] Put 50Kg of hot water (70℃) in a biological breeding tank, add 10Kg of ammonium aluminum sulfate dodecahydrate, 20Kg of urea, 40Kg of potassium dihydrogen phosphate, stir thoroughly to dissolve and disperse the solubles, then add 2Kg of sodium Bean bacteria strains, fully stirred and placed for 12 hours, and then natto bacteria liquid.

[0026] Put 1000Kg of soil water-retaining agent into the mixer, start the mixer to slowly spray the above-mentioned natto bacteria liquid, after spraying, continue to stir evenly and balance, and dehydrate to moisture content ≤ 8%, namely the soil biological enzyme water-retaining agent.

Embodiment 3

[0028] Put 80Kg of hot water (60℃) in a biological breeding tank, then add 3Kg of Span 20, stir and disperse evenly, add 10Kg potassium aluminum sulfate dodecahydrate, 10Kg aluminum ammonium sulfate dodecahydrate, 20Kg urea, 40Kg phosphoric acid Potassium dihydrogen, stir thoroughly to dissolve and disperse the solubles evenly, then add 2Kg of natto bacteria, and let it stand for 24 hours after fully stirring, and it will become natto bacteria liquid.

[0029] Put 1000Kg of soil water-retaining agent in the mixer, start the mixer to slowly spray the above-mentioned natto bacteria liquid, after spraying, continue to stir evenly and balance, and dehydrate to moisture content ≤ 8%, namely the soil biological enzyme water-retaining agent.

Abstract

The invention discloses a method for preparing a soil bio-enzyme water-retaining agent. The method comprises the following steps of: (1) adding bacillus natto strains into a biological culture solution, and fermenting and propagating to obtain bacillus natto bacterial liquid; and (2) mixing a soil water-retaining agent and the bacillus natto bacterial liquid to obtain the soil immobilized enzyme water-retaining agent. The soil bio-enzyme water-retaining agent has ultra high performance of water absorption, water retention, fertilizer absorption and fertilizer retention and excellent biological performance, can promote the growth of probiotic florae, inhibit virus damage, improve the quality of soil and promote the growth of plants, and is an excellent soil conditioner and plant growth promoter.

Description

technical field [0001] The invention relates to a preparation method of a soil biological enzyme water retaining agent. Background technique [0002] In recent years, due to the lack of water resources, irrational use and irrational cultivation, my country's land desertification has become increasingly serious, and the long-term irrational use of chemical fertilizers has caused soil compaction, soil fertility decline, and ecological damage. In order to change this situation, various types of soil water retaining agents and biological enzymes have appeared successively to improve soil cultivation conditions, drought resistance and water saving. [0003] Water-retaining agent is a high-molecular polymer with super-high water-absorbing and water-retaining capacity made of strong water-absorbing resin. Salt water, when there is a lack of water, it can slowly release water for the soil to absorb water, improve soil condition, and is a good soil humidity control agent; it can abs...
