Embodiment 1

[0021] Embodiment one: the preparation of special microbial fertilizer (A) for seashore saline soil

[0022] 1. Preparation of basic materials: First, mix 35% sludge, 20% cow dung, 10% chicken manure, 15% edible fungus cultivation waste and 0.05% wood vinegar in a mixing device. Then seal the mixed material with a plastic film and ferment for 10 to 12 days. On the 3rd, 6th, and 9th days, turn the pile once respectively. Finally, the fermented material is dried and pulverized.

[0023] 2. Preparation of Salina squamous mold:

[0024] (1) Activation of slant strains: inoculate the strains stored in the -20°C refrigerator into the improved Martin medium (K 2 HPO 4 1g, MgSO 4 ·7H 2 (0.5g, NaCl2g, peptone 5g, glucose 10g, agar powder 10g, 1 / 30000 Bengal red aqueous solution 100mL, water 900mL, natural pH, 121°C damp heat sterilization for 30min) on the inclined surface of the test tube, culture at 28°C for 4 days.

[0025] (2) Preparation of primary seed liquid: add 3 mL of ...

Embodiment 2

[0031] Embodiment two: the preparation of special microbial fertilizer (B) for coastal saline soil

[0032] 1. Preparation of basic materials: First, mix 40% sludge, 15% cow dung, 10% chicken manure, 15% edible fungus cultivation waste and 0.1% wood vinegar in a mixing device. Then seal the mixed material with a plastic film and ferment for 10 to 12 days. On the 3rd, 6th, and 9th days, turn the pile once respectively. Finally, the fermented material is dried and pulverized.

[0033] 2. Preparation of Salina squamous mold:

[0034] (1) Activation of slant strains: inoculate the strains stored in the -20°C refrigerator into the improved Martin medium (K 2 HPO 4 1g, MgSO 4 ·7H 2 (0.5g, NaCl2g, peptone 5g, glucose 10g, agar powder 10g, 1 / 30000 Bengal red aqueous solution 100mL, water 900mL, natural pH, 121°C damp heat sterilization for 30min) on the inclined surface of the test tube, culture at 28°C for 4 days.

Embodiment 3

[0041] Embodiment 3: Application of special microbial fertilizer for seashore saline soil

[0042] The microbial fertilizer of the invention can significantly improve saline soil conditions, promote crop growth and increase yield. From May to October 2012, a controlled experiment was carried out in Qingkou Salt Field, Lianyungang City. The soil is clay loam, with salt content of 13.1g / kg, organic matter of 4.4g / Kg, pH9.1, available phosphorus of 7.3mg / Kg, available potassium of 547.3mg / Kg, and available nitrogen of 48.6mg / Kg. The test crops were seashore mallow and castor, and three treatments were set up for each crop: the microbial fertilizer prepared in Example 1 (A), the microbial fertilizer prepared in Example 2 (B), and the control (CK). Before sowing, the fertilization treatment was to put 20 g of corresponding microbial fertilizer in each hole, and the control did not apply any fertilizer. Routine management during the test. The test was completed at the end of Octo...

Abstract

The invention relates to the technical field of soil fertilizers, in particular to special microbial fertilizer for seaside solonchak, and a preparation method and an application of the microbial fertilizer. The microbial fertilizer comprises the following components in percentage by weight: 35-45% of sludge, 20-25% of cow dung, 10-15% of fowl manure, 15-25% of edible fungi cultivation wastes, 8-12% of arbuscular mycorrhiza funguses, 10-15% of salt marsh apophysis mold and 0.05-0.15% of pyroligneous liquor. The microbial fertilizer has the effects of prompting formation of seaside heavy solonchak soil aggregation, reducing the pH value and the salt content of the soil, improving the soil fertility, and prompting crops to absorb a great amount of essential elements and microelements, such as nitrogen, phosphorus and potassium, and the purposes of prompting the crops to grow and increasing the yield are achieved.

Description

technical field [0001] The invention belongs to the technical field of soil fertilizers, and in particular relates to a special microbial fertilizer for seashore saline soil and its preparation method and application, that is, a kind of microbial fertilizer that can promote the formation of seashore saline soil soil aggregates, reduce soil pH and salt content, improve soil fertility, and promote crop growth. Microbial fertilizer for absorbing nitrogen, phosphorus, potassium and other macroelements and microelements, as well as its preparation method and application. Background technique [0002] my country's coastal saline soil is nearly 20 million hectares, and the tidal flat saline soil area is about 3 million hectares, which is an important reserve land resource in my country. Under the background of my country's growing population and the sharp decrease of available cultivated land, the land use of tidal flats provides an important direction for alleviating the pressure ...
