Embodiment 1

[0021] (1) Select strains, the ratio of effective viable counts of Candida lipolytica, Bacillus licheniformis, Bacillus cactus, photosynthetic bacteria, and Bacillus megaterium is 1:2.5:2:1:0.5;

[0022] (2) Inoculate Candida lipolytica, Bacillus licheniformis, Bacillus cacti, Photosynthetic bacteria, and Bacillus megaterium cultured on the slant into the seed medium, respectively, and cultivate at 27-38° C. to obtain Candida lipolytica, respectively. , Bacillus licheniformis, Bacillus cactus, photosynthetic bacteria, Bacillus megaterium seed liquid;

[0023] (3) liquid fermentation culture: the various sub-liquids obtained in step (1) are respectively transferred into the fermentation medium at a volume ratio of 5%, 27~38 ℃, under the condition of dissolved oxygen ≥ 20%, fermentation is carried out, and fermentation is carried out. Culture for 96 to 168 hours to obtain Candida lipolytica fermentation broth, Bacillus licheniformis fermentation broth, Bacillus cactus fermentati...

Embodiment 2

[0026] 1. Strawberry varieties tested: Jiujiu strawberry.

[0027] 2. Test site: Yiquan Town, Donggang City, Dandong City, Liaoning Province.

[0028] 3. Test method: Select the strawberry planting base that has been continuously cropped for many years, and divide it into two test areas, wherein the test area 1 uses the microbial inoculum of Example 1 to carry out soil improvement, watering or drip irrigation once a week, and the dosage per mu per time is 5kg, used continuously throughout the growth cycle, the test area 2 was the control group, and the ordinary strawberry planting method was used for planting, and other planting parameters and pest control were the same.

Abstract

The invention belongs to the technical field of agricultural planting and soil microorganisms, and particularly relates to a special soil improvement microbial agent for strawberries as well as a preparation method and application of the special soil improvement microbial agent. Active ingredients of the microbial agent are candida lipolytica, bacillus licheniformis, bacillus cereus, photosynthetic bacteria and bacillus megatherium, the ratio of the effective viable count of the candida lipolytica, the bacillus licheniformis, the bacillus cereus, the photosynthetic bacteria and the bacillus megatherium is 1: 2.5: 2: 1: 0.5, and the viable count of the microbial agent is (3-10) * 10 <9> / mL. The special soil improvement microbial agent for strawberries provided by the invention is balanced in nutrition, and is beneficial to maintaining fertility and improving the physical and chemical properties of soil. After the microbial agent is used, the picking period is shortened, and the overall yield is increased by 30% or above. Strawberry hardness is improved, and transportation is facilitated. The strawberries have higher sugar content and better mouth feel.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting and soil microorganisms, and in particular relates to a strawberry-specific soil-improving microbial inoculum and a preparation method and application thereof. Background technique [0002] Strawberry has become the most popular health fruit with its vitamin content 10 times higher than other fruits and the anti-cancer effect of unique ellagic acid. Due to the high cost of moving strawberry planting facilities, long annual production and use period, and continuous cropping of facilities is very common, long-term planting in the same field, harmful microorganisms and bacteria gradually accumulate, which is very easy to cause the breeding and spread of diseases and insect pests, and more and more harm to plants. The more serious it is, it will lead to a reduction in production or even no harvest. The continuous cropping obstacle of strawberry is mainly caused by the factors of soil ob...
