Description

Technical Field

[0001] The present invention relates to the technical field of microbial fertilizers, and particularly relates to a biological bacterial fertilizer containing waste of Morchella esculenta nutrient bags, a preparation method thereof, and an application thereof. Background Art

[0002] In recent years, with the rapid development of the edible mushroom industry, large amounts of nutrient bag wastes have been generated from the large-scale cultivation of high-value-added edible mushrooms such as Morchella esculenta. Nutrient bags are usually processed from agricultural and forestry by-products such as wheat and rice husks. After inoculating mycelium to complete nutrient supply, the residues still contain incompletely degraded lignocellulose, mycelial residues, extracellular enzymes, and secondary metabolites. At present, these waste nutrient bags are mainly treated by landfill or incineration. However, landfill is likely to cause soil leachate pollution, and incineration will release harmful gases (such as dioxins) and cause waste of resources.

[0003] For microbial bacterial fertilizers, existing microbial bacterial fertilizers mostly adopt single strains or combinations of strains with repeated functions, and there are certain functional short boards in the application process, and may not be able to take into account multiple functional requirements such as organic matter degradation, heavy metal passivation, nutrient activation, and stress resistance induction.

[0004] Based on the above, it is very promising to obtain a bacterial fertilizer that can effectively utilize waste of edible mushroom nutrient bags and simultaneously meet the multiple functional requirements of microbial bacterial fertilizers. Summary of the Invention

[0005] The purpose of the present invention is to provide a biological bacterial fertilizer containing waste of Morchella esculenta nutrient bags, which can effectively promote the growth and development of the root systems of fruit and vegetable plants, improve the yield and quality of fruits and vegetables, and enhance the ability of fruit and vegetable plants to resist the occurrence of diseases and pests.

[0068] Test Example 1

[0069] Select a planting field in Lugao Village, Yaodu Town, Qingbaijiang District to plant tomatoes. Select tomato varieties that are widely planted locally and have good adaptability. The seedlings are sourced from the Chenxiang Agricultural and Trade Seedling Market in Qingbaijiang District. The test is set up with 6 groups, including the Example 1 group, the Comparative Example 1 group, the Comparative Example 2 group, the Comparative Example 3 group, the Comparative Example 4 group, and the control group. Each group has 3 replicates, for a total of 18 planting plots. The area of each planting plot is 2m 2 , and according to the standard of planting 2000 holes per mu, each plot plants 6 holes, and each hole plants 2 plants. After the planting survives, leave 1 strong plant per hole. The tomato planting period is from May 14th to August 20th, 2024.

[0070] The control group is applied with a traditional special compound fertilizer for vegetable planting, with a nitrogen-phosphorus-potassium ternary compound fertilizer content (N:P2O5:K2O = 15:15:15); the other groups are respectively applied with the corresponding prepared bio-fertilizer. At the time of planting, 0.05 kg is applied and mixed evenly with the soil in the hole as the base fertilizer. After planting, immediately water with root-fixing water, and water once every other day until survival. Then, water according to the soil humidity situation; 0.05 kg / hole is top-dressed with water 15 days after planting, and 0.05 kg / hole is top-dressed when the first young fruits appear. That is, the total fertilizer application amount per plot is 0.15 kg.

[0071] (I) Soil physical and chemical properties

[0072] Take soil samples before planting and during the fruiting period respectively, and conduct soil physical and chemical index tests. The physical and chemical indexes include organic matter content, available nitrogen content, available phosphorus content, and available potassium content. The detection method refers to "Soil Agricultural Chemistry Analysis" (Bao Shidan. Soil Agricultural Chemistry Analysis [M]. Beijing: China Agricultural Press.).

[0073] Before planting, the organic matter content of the soil is 21.57 g / kg, the available nitrogen content is 78.11 mg / kg, the available phosphorus content is 33.95 mg / kg, and the available potassium content is 59.02 mg / kg.

[0074] Table 1 Soil physical and chemical index conditions of different treatment groups before planting and during the fruiting period

[0075]

[0076] As can be seen from Table 1, compared with the control group, the physical and chemical indexes of the soil in the result period of the groups of Comparative Examples 1-4 and Example 1 increased significantly, and among them, the improvement in Example 1 group was relatively more significant. That is to say, it shows that the biological bacterial fertilizer described in the present invention can effectively improve the physical and chemical properties of the soil.

[0077] (2) Plant growth indexes

[0078] 30 days after the tomato seedlings were planted, 3 plants were randomly selected at fixed points in each plot to measure the growth indexes such as plant height (main stem height), stem diameter (main stem diameter 2 cm away from the soil), and internode number. The results are shown in Table 2.

[0079] Table 2 Growth indexes of tomato plants in different treatment groups

[0080] Group Plant height / cm Stem diameter / mm Number of internodes / each Example 1 group 94 65 21 Control 1 group 84 47 16 Control 2 group 90 61 19 Control 3 group 88 54 19 Control 4 group 85 49 17 Control group 73 32 13

[0081] As can be seen from Table 2, the growth effects of plant height, stem diameter, and internode number of tomato plants treated with the biological bacterial fertilizer described in the present invention were relatively the most significant.

[0082] (3) Yield

[0083] After the tomatoes were mature, they were harvested and weighed, and the yield per plant and the mass of a single fruit were counted.

[0084] Table 3 Yield of tomatoes in different treatment groups

[0085] Group Yield per plant / kg Single fruit mass / g Example 1 group 1.69 95.35 Control 1 group 1.37 88.14 Control 2 group 1.61 91.07 Control 3 group 1.53 89.56 Control 4 group 1.42 86.33 Control group 1.25 80.20

[0086] As can be seen from Table 3, the tomatoes in the groups of Comparative Examples 1-4 and Example 1 were higher than the control group in terms of yield per plant and average fruit set number. Among them, the tomato yield in Example 1 group was relatively the highest.

[0087] (4) Quality

[0088] After the tomatoes were mature, 3 fruits with similar sizes were selected from each replicate for quality determination, including soluble solid content, organic acid content, and VC content. The soluble solid content was measured by an ATAGO hand-held refractometer, the organic acid content was measured by sodium hydroxide titration method (Li Xiaofang, Zhang Zhiliang, 2016. Experimental Guidance for Plant Physiology, Beijing: Higher Education Press.), and the VC content was measured by molybdenum blue colorimetry (Li Hesheng. 2000. Principles and Techniques of Plant Physiological and Biochemical Experiments. Beijing: Higher Education Press).

[0089] Table 4 Quality indexes of tomatoes in different treatment groups

[0090] Group Soluble solids(%) Organic acid(g / L) VC(mg / kg) Example 1 group 5.84 1.28 112.05 Control 1 group 5.45 1.19 90.34 Control 2 group 5.70 1.26 109.82 Control 3 group 5.59 1.23 102.14 Control 4 group 5.50 1.17 95.52 Control group 5.21 1.11 78.23

[0091] As can be seen from Table 4, compared with the control group, the soluble solids content, organic acid content, and VC content of tomato fruits in Example 1 and Comparative Examples 1-4 were all significantly increased.

[0092] (V) Pest and disease control

[0093] Investigate and count the number of plants with tomato root rot. Taking the browning of the plant roots or the death of the plant as the standard, calculate the incidence rate: Incidence rate = Number of diseased plants / Total number of plants × 100%.

[0094] Table 5 Incidence of tomato root rot in different treatment groups

[0095] Group Incidence rate(%) Example 1 group 1.67 Control 1 group 6.15 Control 2 group 2.34 Control 3 group 3.01 Control 4 group 5.27 Control group 12.05

[0096] As can be seen from Table 5, the incidence rate of tomato root rot in Example 1 group was the lowest, and the plants showed relatively the best performance. That is to say, the biological bacterial fertilizer described in the present invention has a certain effect on preventing and controlling pests and diseases.

[0097] In summary, it can be seen that the biological bacterial fertilizer prepared by the technical solution of the present invention has low cost and rich nutrient elements, can effectively promote the growth and development of the roots of fruit and vegetable plants, improve the yield and quality of fruits and vegetables, and enhance the ability of fruit and vegetable plants to resist the occurrence of pests and diseases; at the same time, it also solves the environmental problem that the nutrient bags are discarded everywhere and difficult to handle after the cultivation of Morchella esculenta, and improves the utilization rate of resources.

[0098] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
