Example Embodiment

[0048] Example 1

[0049] An ecological amendment for coastal saline soil, which is characterized in that it comprises the following components, all of which are parts by weight:

[0050] 30 parts of exogenous beneficial microbial agents, 20 parts of soil beneficial microbial agents, and 10 parts of humic acid.

[0051] The above-mentioned coastal saline soil ecological amendment is prepared as follows:

[0052] (1) Preparation of exogenous beneficial microbial agents:

[0053] Strain activation

[0054] Take Trichoderma sp. T-304-1071 with the preservation number of CGMCC No. 5394, inoculate it in a PDA medium and culture at 26°C for 5 days to obtain activated Trichoderma sp. T-304-1071;

[0055] PDA medium: 200g potato, 20g glucose, 15g agar powder, 1000ml water.

[0056] Seed culture

[0057] Dilute the activated Trichoderma sp. T-304-1071 spores with sterile water and insert them into a 250ml Erlenmeyer flask containing 50ml PD medium, culture at 26℃, 180r / m, and shaking for 3 days to o...

[0092] Example 2

[0093] An ecological amendment for coastal saline soil, which is characterized in that it comprises the following components, all of which are parts by weight:

[0094] 30 parts of exogenous beneficial microbial inoculum, 20 parts of soil beneficial microbial inoculum, 10 parts of humic acid, and 40 parts of crushed cotton straw. The length of the cotton stalk is 3-5 cm.

[0095] The preparation method of the coastal saline soil ecological amendment is as described in Example 1, the difference is that:

[0096] Exogenous beneficial microbial agent is Trichoderma spore content 7.3×10 8 cfu / g exogenous beneficial microorganisms;

[0097] Beneficial microbial agent for soil habitat is Aspergillus spore content 1.6×10 8 cfu / g beneficial microorganisms;

[0098] After mixing the exogenous beneficial microbial inoculum, the soil beneficial microbial inoculum, humic acid and crushed cotton straw in parts by weight, the coastal saline soil ecological improver is obtained.

Abstract

The invention relates to ecologic conditioner for salt-affected soil by the sea, and a preparation method and application of the ecologic conditioner. The ecologic conditioner comprises the following components by part by weight: 25 to 30 parts of exogenous beneficial microbial agent, 20 to 25 parts of soil beneficial microbial agent, and 5 to 10 parts of humic acid. The invention further provides the application of the ecologic conditioner in conditioning the salt-affected soil ecology by the sea. The ecologic conditioner can promote the formation of soil water-stable aggregates and improve soil texture, thereby promoting the building and the maintaining of soil beneficial microbiological communities; meanwhile, the ecologic conditioner can promote the uptake of nitrogen, phosphorus, potassium and microelements of crops, improve the utilization ratio of fertilizers, and buffer the manurial effect.

Description

technical field [0001] The invention relates to an ecological improver for coastal saline soil, a preparation method and application thereof, and belongs to the technical field of soil ecological improver. Background technique [0002] The Yellow River Delta is a new land formed by the Yellow River land-building movement in the past century. The groundwater is shallow and highly mineralized, and the underground salt is easy to rise to the surface, resulting in soil salinization and widespread saline-alkaline wasteland. The area of ​​salinized land in this area reaches 442,900 hm 2 , accounting for more than half of the total area of ​​the whole region, among which, 236,300 hm of heavily salinized soil and saline-alkali bare ground 2 , accounting for about 28.4% of the land area in the area, the saline soil is mainly coastal saline soil, the salinity is mainly chloride, the salinity of the soil surface varies from 0.4% to 3%, the soil structure is poor, and the fertility is ...
