Problems solved by technology

Therefore, applying soil conditioner to improve soil condition is a soil improvement method commonly used in the prior art. Although there are many kinds of soil conditioners in the prior art, the existing soil conditioner still cannot play a good role in water retention and ventilation. , The technical effect of fertilizer preservation, there are technical problems of slow soil improvement speed and poor improvement effect, which is not conducive to improving the planting yield of crops

Embodiment 1

[0031] (1) In terms of mass parts, take the following raw materials: 80 parts of peat, 30 parts of carboxymethyl cellulose, 20 parts of fly ash, 25 parts of poultry manure (pig manure), 5 parts of microbial bacterial agents (mass parts Calculated, 3 parts of Paecilomyces, 5 parts of Bacillus subtilis, 5 parts of Bacillus megaterium, 5 parts of jelly-like Bacillus, and 5 parts of nitrogen-fixing bacteria are mixed, and the total number of effective bacteria is 10 9 cfu / g), 20 parts of nitrogen, phosphorus and potassium fertilizers (available nitrogen fertilizer, quick-acting potassium fertilizer, and quick-acting phosphate fertilizer are mixed according to the ratio of mass ratio 1:0.3:0.3), 3 parts of trace elements (iron nitrate, magnesium nitrate, zinc nitrate, calcium phosphate , manganese nitrate, potassium borate, and ammonium molybdate are mixed according to equal quality).

[0032] (2) Mix peat, fly ash, poultry manure and microbial fermentation agent (10 parts of Bacillu...

Embodiment 2

[0035] With embodiment 1, the difference is that in step (2), peat, fly ash, poultry manure are pretreated before mixing with the microbial fermentation inoculant, and the specific steps are as follows: peat, fly ash, poultry manure are mixed Finally, adjust the water content to 80% (50-80% has a similar technical effect), and after ultrasonic mixing, microwave treatment under 500W for 60min (300-500W treatment for 30-60min has a similar technical effect), and then spray dry Get preprocessed materials.

Embodiment 3

[0037] Same as Example 1, the difference is that the anaerobic fermentation process of step (2) is omitted, and the materials are directly mixed.

Abstract

The invention relates to the technical field of soil improvement, in particular to a water-retaining and fertilizer-retaining soil conditioner and a preparation method thereof. The fertilizer comprises the following raw materials in parts by mass: 80-120 parts of peat, 30-40 parts of carboxymethyl cellulose, 20-30 parts of fly ash, 10-25 parts of livestock manure, 1-5 parts of a microbial agent, 10-20 parts of a nitrogen-phosphorus-potassium fertilizer and 1-3 parts of trace elements. According to the invention, the peat, the fly ash and the livestock manure are matched with the microbial fermentation inoculant and the microbial inoculant as well as a proper amount of nitrogen-phosphorus-potassium quick-acting fertilizer, so the quick-acting fertilizer is provided for crops while water and fertilizer are preserved and a soil condition is improved, and the yield of the crops is increased.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a water- and fertilizer-retaining soil improver and a preparation method thereof. Background technique [0002] Soil improvement refers to the use of soil science, biology, ecology and other multidisciplinary theories and technologies to eliminate or prevent unfavorable factors that affect crop growth and cause soil degradation, improve soil properties, increase soil fertility, and create a good soil environment for crops A collective term for a series of technical measures of conditions. The basic measures include: ①Soil water conservancy improvement, such as establishing farmland drainage and irrigation projects, adjusting groundwater level, improving soil moisture status, eliminating and preventing swamp and salinization; ②Soil engineering improvement, such as using land leveling, building terraces, diverting flood water Engineering measures such as flooding and silt...
