Problems solved by technology

Although this improver improves the water retention effect compared with traditional fertilization, the water retention effect is still unsatisfactory, and it is not suitable for desert areas. In addition, the formulation and preparation process of the improver are relatively complicated and the cost is high. For example, organic The fermented product needs 6 kinds of substances to be fermented according to a certain ratio, and additionally need to add pH buffer and soil disinfectant, etc.

Embodiment 1

[0051] Embodiment 1: Preparation of decomposed straw

[0052] 1. Main raw materials

[0053] 1. The first microbial agent, by weight:

[0054]

[0055]

[0056] Requirements for the prepared compound bacterial agent: acid protease ≥ 2000u / g, neutral protease ≥ 10000u / g, cellulase ≥ 10000u / g, and the corresponding enzyme preparation is added to the insufficient part.

[0057] Bacillus subtilis KX-1 can survive and reproduce at 2-8°C.

[0058] 2. Volcanic rock biological agents

[0059] Volcanic rock biological preparations are made of porous and large surface area structural properties of volcanic rocks, containing a large amount of silicon, potassium, sodium, iron, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt and other dozens of minerals and trace elements, as well as the chelation of heavy metals, using it as a carrier, implanting a variety of beneficial microbial flora that has been verified to be harmless to humans, animals and o...

Embodiment 2

[0120] Example 2: Preparation of biofloc

[0121] Biofloc preparation includes the following steps:

[0122] (1) The decomposed stalks prepared according to the method of Example 1 are pulverized into about 80 meshes with a pulverizer to obtain decomposed stalk powder;

[0123] (2) Add 200 grams of the first microbial bacterial agent per kilogram of decomposed straw powder Add the first microbial bacterial agent to the decomposed straw powder, and then spray nitrifying bacteria and denitrifying bacteria in turn, the addition of nitrifying bacteria and denitrifying bacteria is 100ml Every kilogram of decomposed straw powder can get biofloc.

[0124] For a picture of the resulting biofloc see Figure 5 .

[0125] The organic indicators of the biofloc obtained in this example and the biofloc produced by a foreign company were tested, and the results are shown in Table 4. In addition, the trace elements of the biofloc in this example were tested, and the results are shown in Ta...

Embodiment 3

[0130] Example 3: Soil conditioner

[0131] In the following examples, volcanic ash: produced in Changchun, Jilin; biofloc: prepared by the method and conditions of Example 2 of the present invention (60 mesh); γ-polyglutamic acid: produced by Kunshan Huake, pure biological fermentation; γ-polyglutamic acid Acid water glue: produced by Kunshan Huake Biotechnology, it is absorbed by river water for 60 hours, and the absorption rate is 20 times.

[0132] Example 3-1 This example provides a soil conditioner whose raw materials are composed of volcanic ash, biofloc and γ-PGA hydrogel, the mass ratio of volcanic ash and biofloc is 1:1, and the feeding volume of γ-PGA hydrogel is the same as The mass ratio of volcanic ash is 5L / kg. When in use, mix volcanic ash, biofloc and soil evenly, then add γ-PGA water glue and stir evenly.

[0133] Example 3-2 This example provides a soil conditioner whose raw materials are composed of volcanic ash, biofloc and γ-PGA hydrogel, the mass ratio ...

Abstract

The invention relates to a soil conditioner suitable for desertification control and application thereof in desertification control. The soil conditioner is combination of multiple raw materials, including volcanic ash, gamma-polyglutamic acid hydrogel and biofloc, wherein the biofloc comprises rotten straw powder, a first microbial inoculant, nitrobacteria and denitrifying bacteria; the first microbial inoculant comprises Bacillus subtilis and selective actinomycetes; the first microbial inoculant accounts for 5-25 wt% of the rotten straw powder; and the amount of nitrobacteria and denitrifying bacteria is greater than or equal to 80ml/kg rotten straw powder. The soil conditioner has excellent moisture retention and water storage effects, is capable of enhancing the organic matter content in soil, regulating the pH value of the soil and promoting the release of available nitrogen, phosphorus and potassium, and creates a favorable soil physical and nutritional environment for plant growth. Meanwhile, the conditioner has the advantages of simple formula, simple preparation process and lower cost.

Description

technical field [0001] The invention relates to a soil conditioner, its preparation method and its application in desert control. Background technique [0002] At present, the desert control method is mainly to plant ecological forests to control sand, but due to the limited soil conditions in desert areas, large water consumption and poor planting effect of vegetation, there is an urgent need to develop methods that can improve desert soil and planting methods for desert soil . Improvement of desert soil must solve the problems of fast water seepage and evaporation in the soil, lack of organic matter and fertility in the soil, and change the soil into a bulk structure that does not gather together. [0003] The existing soil improvers used to improve desert soil are mainly direct application of organic fertilizer or peat soil, and the improvement effect is not good. Chinese invention patent application CN104910921A discloses a sandy soil improver, its composition by mass ...
