Description

Technical Field

[0001] This invention relates to the field of agricultural waste resource utilization technology, specifically to a method for the resource recycling of greenhouse melon seedlings. Background Technology

[0002] Currently, the main methods for disposing of greenhouse melon vines include indiscriminate discarding, burning, and direct return to the field. Indiscriminate discarding not only occupies land resources but also breeds mosquitoes and spreads pathogens; burning produces large amounts of harmful gases, polluting the atmosphere; while direct return to the field achieves nutrient cycling to some extent, it presents the following serious problems:

[0003] High risk of soil-borne disease transmission: Melon vines carry a large number of pathogens such as wilt, anthracnose, and powdery mildew, as well as insect eggs such as root-knot nematodes. Directly returning them to the field will cause pathogens to accumulate in large quantities in the soil, making soil-borne diseases in greenhouses worse year by year. In severe cases, it can lead to crop yield reduction of more than 30% or even crop failure.

[0004] Slow decomposition and low nutrient utilization: The vines of melons have a high content of lignin and cellulose (lignin content is about 15%-20%, and cellulose content is about 25%-30%). Under natural conditions, it takes 6-12 months to fully decompose. They cannot provide effective nutrients to crops during the current season, and they will compete with crops for nitrogen during the decomposition process, leading to nitrogen deficiency in the seedling stage of crops.

[0005] Environmental pollution is a prominent issue: the water content of melon vines is as high as 75%-85%, and direct composting can easily produce foul odors and leachate, polluting the soil and groundwater. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a method for the resource-based recycling of greenhouse melon vines. This method, through a technical system of "high-temperature steam flash explosion, microwave sterilization pretreatment, segmented temperature-controlled directional composting, functional microbial agent compounding, and in-situ field improvement," solves the problems of soil-borne disease transmission, slow composting, and low nutrient utilization associated with traditional melon vine returning to the field, thus achieving efficient, safe, and resource-based recycling of greenhouse melon vines.

[0007] The present invention discloses a method for the resource recycling of greenhouse melon vines, the method being as follows:

[0008] S1. Pretreatment of melon vines: After removing impurities, the melon vines are cut into sections and subjected to high-temperature steam flash explosion treatment; the melon vines after flash explosion treatment are immediately subjected to microwave sterilization treatment to obtain pretreated melon vine material;

[0009] S2. Ingredients and mixing: Mix the pretreated melon seedlings, livestock and poultry manure, biochar and conditioner in a mass ratio of 100:(20-30):(5-10):(3-5), adjust the moisture content of the materials to 55%-65% and the carbon-nitrogen ratio to 25-30:1;

[0010] S3. Segmented Temperature-Controlled Directional Composting: The materials mixed in S2 are fed into a closed aerobic fermenter, inoculated with a compound composting agent, and subjected to segmented temperature-controlled composting.

[0011] First stage: Control the temperature at 35-40℃, the ventilation rate at 0.2-0.3 m³ / (h•kg material), and ferment for 2-3 days;

[0012] Second stage: Control the temperature at 58-62℃, the ventilation rate at 0.4-0.5m³ / (h•kg material), and ferment for 5-7 days;

[0013] The third stage: control the temperature at 40-45℃, the ventilation rate at 0.1-0.2m³ / (h•kg material), and ferment for 3-5 days; turn the pile over once every day during the fermentation process to obtain well-rotted melon vine fertilizer;

[0014] S4. Compound preparation of functional microbial agents: Inoculate the decomposed melon seedling fertilizer with compound functional microbial agents at a rate of 0.5%-1% of the mass of the decomposed melon seedling fertilizer. After mixing evenly, let it stand at 25-30℃ for 2-3 days to obtain functional melon seedling organic fertilizer.

[0015] S5. Greenhouse in-situ soil improvement: Evenly spread functional melon seedling organic fertilizer on the surface of the greenhouse soil at a rate of 1500-2500 kg / mu, then use a rotary tiller to plow it into the soil layer, water it thoroughly, and seal the greenhouse for 7-10 days before planting the next crop.

[0016] Furthermore, the process parameters for the high-temperature steam flash explosion treatment in step S1 are: steam pressure 1.5-2.0 MPa, pressure holding time 60-90 seconds, and pressure release time ≤0.5 seconds.

[0017] Furthermore, the process parameters for microwave sterilization in step S1 are: microwave power 800-1200W, frequency 2450MHz, processing time 3-5 minutes, and material thickness 5-8cm.

[0018] Furthermore, the livestock and poultry manure mentioned in step S2 is one or more of chicken manure, pig manure, or cow manure, and has undergone solid-liquid separation treatment with a water content of ≤60%.

[0019] Furthermore, the biochar mentioned in step S2 is prepared by pyrolysis of corn stalks or rice husks at 500-600℃, with a particle size of 0.5-1mm.

[0020] Furthermore, the conditioning agent mentioned in step S2 is one or both of sawdust or mushroom residue.

[0021] Furthermore, the compound composting agent mentioned in step S3 is composed of Bacillus subtilis, Aspergillus niger, and Trichoderma viride mixed in a mass ratio of 3:2:1, with an effective viable count ≥5×10⁻⁶. 9 CFU / g, with an inoculum size of 0.3%-0.5% of the mass of the mixture.

[0022] Further, the composite functional microbial agent described in step S4 is composed of Bacillus amyloliquefaciens, Paecilomyces lilacinus, and Bacillus mucilaginosus mixed in a mass ratio of 2:2:1, with an effective viable count ≥1×10⁻⁶. 10 CFU / g.

[0024] Functional melon seedling organic fertilizer prepared according to the method described in this invention.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Thorough sterilization and low risk of soil-borne disease transmission: This invention employs a combination of high-temperature steam flash explosion and microwave sterilization. The high temperature, high pressure, and mechanical shearing force generated by the high-temperature steam flash explosion can destroy the cell wall structure of the melon vines, exposing pathogens and insect eggs inside. The subsequent microwave treatment utilizes the thermal and non-thermal effects of microwaves to rapidly kill the exposed pathogens and insect eggs. Experimental results show that the pretreatment method of this invention can achieve a pathogen kill rate of over 99.5% on melon vines and a root-knot nematode egg kill rate of over 99%, completely solving the problem of soil-borne disease transmission associated with traditional melon vine return to the field.

[0027] 2. Rapid decomposition and high nutrient utilization: High-temperature steam flash explosion treatment can destroy the lignocellulose structure of melon vines, reducing the crystallinity of cellulose and hemicellulose and increasing the specific surface area, which is conducive to the attachment and decomposition of microorganisms. Simultaneously, this invention employs segmented temperature-controlled directional decomposition technology, combined with a special compound decomposition agent, which can significantly improve decomposition efficiency. The entire decomposition cycle only takes 10-15 days, shortening it by more than 2 / 3 compared to traditional composting. Furthermore, closed-loop aerobic fermentation can effectively reduce nutrient loss, controlling the nitrogen loss rate to below 5%. The organic matter content of the decomposed melon vine fertilizer is ≥45%, and the total nutrient (N+P2O5+K2O) content is ≥5%, with nutrient utilization rate increased by more than 30% compared to traditional composting.

[0028] 3. Comprehensive Functions and Significant Soil Improvement: This invention incorporates a compound functional microbial agent into well-rotted melon vine fertilizer. Among these, *Bacillus amyloliquefaciens* inhibits the growth of soil pathogens, *Paecilomyces lilacinus* controls root-knot nematodes, and *Bacillus mucilaginosus* activates phosphorus and potassium in the soil. Simultaneously, the added biochar improves soil aggregate structure and enhances water and fertilizer retention capacity. Experimental results show that after using this functional melon vine organic fertilizer, the organic matter content of greenhouse soil increased by 20%-30%, bulk density decreased by 10%-15%, the number of soil microorganisms increased by more than 50%, and the incidence of soil-borne diseases decreased by more than 80%.

[0029] 4. Environmentally friendly and economically beneficial: This invention realizes the full utilization of greenhouse melon seedlings, avoiding environmental pollution problems caused by indiscriminate disposal and burning; at the same time, the method and process of this invention are simple, easy to scale up, and have low production costs, resulting in significant economic benefits.

[0065] Experiment Example 1: Sterilization Efficacy Test

[0066] Watermelon seedlings before treatment by the method in Example 1 (denoted as Q1), watermelon seedlings after treatment by the method in Example 1 (denoted as H1), and watermelon seedlings after crushing in Comparative Example 1 (denoted as D1) were taken respectively. The number of Fusarium wilt, anthracnose and root-knot nematode eggs were detected and the kill rate was calculated. The results are shown in Table 1.

[0067] Table 1. Sterilization effect of different treatment methods

[0068]

[0069] As can be seen from Table 1, the high-temperature steam flash explosion-microwave sterilization method of the present invention has an excellent killing effect on pathogens and root-knot nematode eggs on watermelon seedlings, with a killing rate of over 99%; while the traditional pulverization treatment has a very low killing rate and cannot effectively control the spread of soil-borne diseases.

[0070] Experiment Example 2: Decomposition Effect Detection

[0071] The composting indexes of the watermelon seedling fertilizer after composting in Example 1 and the composted manure after composting in Comparative Example 2 were tested respectively, and the results are shown in Table 2.

[0072] Table 2. Fermentation effects of different fermentation methods

[0073]

[0074] As can be seen from Table 2, the segmented temperature-controlled directional composting method of the present invention can significantly shorten the composting cycle, improve the composting quality, and reduce nutrient loss. The composting cycle of Example 1 is only 15 days, which is half that of Comparative Example 2; the organic matter content and total nutrient content are both higher than the national standard, and the nitrogen loss rate is only 4.2%, far lower than the 25.6% of Comparative Example 2.

[0075] Experiment Example 3: Soil Improvement Effects and Crop Yield Detection

[0076] Field trials were conducted in watermelon greenhouses that had been continuously cropped for 5 years. Treatments were performed using the methods described in Example 1, Comparative Example 1, and Comparative Example 2, with a control group (CK) receiving no organic fertilizer. Each treatment was replicated in triplicate, with each replicate plot measuring 20 m². 2 The next watermelon crop was planted with the variety "Jingxin No. 1", and conventional field management was implemented. Soil physicochemical properties, soil-borne disease incidence, and watermelon yield were measured at harvest, and the results are shown in Tables 3 and 4.

[0077] Table 3 Effects of different treatment methods on soil physicochemical properties

[0078]

[0079] Table 4. Effects of different treatment methods on the incidence of soil-borne diseases

[0080]

[0081] As shown in Tables 3 and 4, the functional melon seedling organic fertilizer of the present invention can significantly improve the physical and chemical properties of greenhouse soil, increase soil fertility, reduce the incidence of soil-borne diseases, and increase crop yield. Compared with the control (CK), the soil organic matter content of Example 1 increased by 34.4%, the bulk density decreased by 11.7%, and the contents of available nitrogen, available phosphorus, and available potassium increased by 44.7%, 50.6%, and 37.6%, respectively; the incidence of Fusarium wilt and root-knot nematode diseases decreased by 88.1% and 86.4%, respectively; and the watermelon yield increased by 24.91%. Compared with Comparative Example 2, the soil improvement and yield increase effects of Example 1 are also more significant.
