Embodiment 1

[0034] The alkaloid saline-alkali soil conditioner described in this embodiment is prepared from the following components in parts by weight through the following steps:

[0035] (1) Inoculate the preserved Rhodopseudomonas marsh, Pichia membranum, Lactobacillus casei, and Streptomyces flavinus into a sterile sterile solution containing carbon source, nitrogen source, inorganic salt and water, respectively. In the culture medium, and cultivated under the adaptation conditions for 3-5 days respectively, then the bacterial classification obtained by fermentation is mixed for subsequent use according to the weight ratio of 3:5:4:3;

[0036] (2) The kelp is sterilized and disinfected at high temperature (above 100°C), soaked for 48 hours, pulverized to 80 mesh, ground to 120 mesh, extracted from mannitol and sodium alginate, and then transported to a pulping machine for pulping to obtain the obtained Said seaweed slurry;

[0037] (3) Mix 5 parts of bacterial species obtained in s...

Embodiment 2

[0042] The alkaloid soil conditioner of the present invention is prepared by the following preparation method:

[0043] (1) Inoculate the preserved Rhodopseudomonas marsh, Pichia membranum, Lactobacillus casei, and Streptomyces flavonoids into a sterile sterile solution containing carbon source, nitrogen source, inorganic salt and water, respectively. In the culture medium, cultured for 3-5 days under adaptation conditions, respectively, the culture solutions obtained from each fermentation were mixed according to a weight ratio of 6:3:2:1 to obtain the required bacterial species for subsequent use;

[0044] The Lactobacillus casei culture medium formula is: peptone 10g, meat extract 10g, yeast extract 5g, dipotassium hydrogen phosphate 2g, triammonium citrate 2g, sodium acetate 5g, glucose 20g, Tween-80 1mL, MnS0 4 ·H 2 O 0.25g, MgS0 4 ·7H 2 O 0.58g, agar 20g, sterilized CaCO 3 10g, distilled water 1000mL. Adjust the pH value to 6.2-6.4, put the prepared culture medium i...

Embodiment 3

[0054] The alkaloid saline-alkali soil conditioner described in this embodiment is prepared from the following components in parts by weight through the following steps:

[0055] (1) Mix the preserved Rhodopseudomonas marsh, Pichia membranum, Lactobacillus casei, and Streptomyces flavis and inoculate them into a suitable sterile culture containing carbon source, nitrogen source, inorganic salt and water In the base, cultivate at 25-35°C for 3-5 days to obtain the required strains for use;

[0056] Described culture medium comprises: glucose 30g / L, bran 20g / L, yeast extract 5g / L, MgSO 4 2g / L, distilled water, adjust pH to 5.0.

[0057](2) The kelp is sterilized and disinfected at high temperature (above 100°C), soaked for 48 hours, pulverized to 80 mesh, ground to 120 mesh, extracted from mannitol and sodium alginate, and then transported to a pulping machine for pulping to obtain the obtained Said seaweed slurry;

[0058] (3) Take 5 parts of bacterial species obtained in s...

Abstract

The invention relates to a saline-alkali soil improving agent and its preparation method. The preparation method comprises the following steps: mixing Rhodopseudomonas palustris, Pichia membranefaciens Hansen bacterium, lactobacillus casei, Staestomyces microflavus and seaweed slurry, organically combining a plurality of beneficial microorganisms and seaweed through multi-time fermentation, culturing in a compound mode to obtain a novel microorganism agent-seaweed bio-fungus. adding a proper amount of humic acid, organic matter, active zeolite powder and molasses, and fermenting and drying the fermented product. The biology saline-alkali soil improving agent uses a plurality of microorganisms and employs strong effects of a unique ionic adsorbent, an organic neutralization balancing agent, an ion-exchange agent and a beneficial bacteria conversion starter to achieve the purposes of improving the soil environment, regulating acid-base balance, reducing the salt content, effectively raising the soil fertility and permeability, loosening the soil, eliminating the soil hardening, degrading the harmful substance and promoting the accumulation and conversion of the organic substance.

Description

technical field [0001] The invention belongs to a microbial fertilizer, in particular to a soil conditioner for improving soil salinity and a preparation method thereof. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. Soil salinization is a worldwide problem. The area of ​​saline soil in the world is about 1 billion hectares. my country has 99.13 million hectares, or about 1.47 billion mu. More than 100 cities in the country are located in saline-alkali distribution areas. Nearly 500 million mu of land has been lost or abandoned due to salinization, mainly concentrated in the arid and semi-arid regions of North China, Northwest China and Northeast China. In addition, during the cultivation process, the long-term excessive application of chemical fertilizers leads to the intensification of secondary salinization of the soil, serious compaction, and the continuo...
