Description

Technical Field

[0001] This invention belongs to the field of fruit tree cultivation and pest and disease control, specifically a method for the synergistic application of orchard sanitation, soil improvement and attractant application in green control of diseases and pests of bayberry. Background Technology

[0003] Existing pest and disease control technologies for bayberry have the following limitations: 1. Traditional chemical control leads to excessive pesticide residues, increased pesticide resistance in pests such as fruit flies, and the overlap between bayberry ripening and fruit fly peak periods makes safe pesticide application impossible; 2. Single physical trapping only reduces the number of adult insects, ineffective against larvae and pupae; biological control is limited by climate and orchard ecology, resulting in poor stability; the use of insect-proof netting is costly and difficult to promote on a large scale; 3. Long-term fertilizer application leads to soil compaction, soil microecological imbalance, and decreased organic matter content, thus exacerbating disease occurrence; 4. Improper handling of fallen fruit and pruning leaves, and incomplete pest source cleanup, lead to the gradual accumulation of fruit fly populations year by year. Therefore, we propose a synergistic method of orchard sanitation, soil improvement, and attractant application in green pest and disease control for bayberry to address the problems mentioned above.

[0004] The information disclosed above in this background section is only for enhancing the understanding of the background technology of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a synergistic method for orchard sanitation, soil improvement, and attractant application in the green prevention and control of diseases and pests of bayberry, so as to solve the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a synergistic method for green prevention and control of diseases and pests in bayberry, comprising the following steps:

[0007] Step 1: Clean the park during two time slots

[0008] Within 30 days after harvesting, pre-winter basic cleaning is carried out to remove fallen fruit, rotten fruit and diseased branches. The fruit is then transported to a special fermentation tank outside the park, where fermentation agents and straw fragments are added by weight. The tank is then covered with plastic film for anaerobic fermentation for 30 days to produce semi-finished biological organic fertilizer.

[0009] In early March, a deep spring cleaning was carried out, with the entire orchard sprayed with a 5% lime sulfur solution, focusing on the trunks and ground surface. Dense branches were pruned to ensure ventilation and light penetration in the canopy and reduce the risk of white rot.

[0010] Step 2: Soil Microecological Reconstruction

[0011] Prepare customized organic slow-release fertilizer, dig a circular trench along the drip line of the tree canopy, apply 5 kg of slow-release fertilizer per tree, cover with soil and drip irrigate to keep moist, and promote the activation of microbial agents;

[0012] Step 3: Co-processing of induction and deduction

[0013] Prepare food attractants for later use, and prepare repellents to spray on fruit surfaces to repel gall midges;

[0014] Step 4: Intelligent monitoring of the trapping device

[0015] Deploy intelligent trapping devices, hanging 30 IoT traps per hectare, with built-in food attractants and equipped with infrared counters. The devices upload insect population data to the cloud platform in real time. When the daily killing rate exceeds 50 insects / device, an early warning is automatically triggered and the frequency of lemongrass juice spraying is increased.

[0016] Step 5: Synergistic Effect Processing

[0017] For high-value varieties, erect single-plant insect-proof nets with a mesh size of 40 15 days before maturity to block fruit flies from laying eggs; spray a pollution-free flower thinning agent during the flowering period to reduce redundant flowers and fruits and reduce nutrient competition.

[0018] Preferably, in step 1, the fermentation agent includes Bacillus licheniformis and Trichoderma, and the ratio of the fermentation agent to straw fragments is 3:1.

[0019] Preferably, in step 2, the organic slow-release fertilizer formula is: 20-30 parts of bayberry residue, 10-15 parts of rapeseed cake, 1 part of microbial agent, 10-12 parts of maifanite powder, and 5-8 parts of lemongrass extract residue.

[0020] Preferably, in step 2, the depth of the annular groove is 20cm.

[0021] Preferably, in step 3, the food attractant formula is 5% brown sugar, 5% homemade rice vinegar, 1% fruit flavoring, and 0.01% abamectin.

[0022] Preferably, in step 3, the repellent is prepared by diluting lemongrass juice with water at a ratio of 1:5.

[0023] Preferably, in step 5, the flower thinning agent is of the ammonium acetate type.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This invention interrupts the pest reproduction chain through two-stage orchard sanitation, reducing the initial pest population. It enhances soil microbial resistance through soil improvement, increasing soil organic matter and reducing the incidence of onion disease. It achieves precise intervention through synergistic treatment of attractants and repellents. The attractant simulates the fermentation smell of fruit to lure and kill adult insects, while citronella oil interferes with the olfactory location of gall midges, thus blocking oviposition. Through the synergistic application of three stages—orchard sanitation management, soil improvement, and attractant application—this invention innovatively combines waste resource utilization, plant-derived repellents, intelligent monitoring, and ecological regulation, overcoming the shortcomings of unstable efficacy of single technologies and achieving improved quality of bayberries and sustainable maintenance of the orchard's ecological environment. Attached Figure Description

[0026] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this invention. For those skilled in the art, other drawings can be obtained based on these drawings.

[0027] Figure 1 This is a schematic diagram of the prevention and control process of the present invention. Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] A synergistic method for green control of diseases and pests in bayberry, involving orchard sanitation, soil improvement, and attractant application, includes the following steps:

[0031] Step 1: Clean the park during two time slots

[0032] Within 30 days of harvesting, a pre-winter cleanup is carried out to remove fallen fruit, rotten fruit, and diseased branches. The fruit is then transported to a dedicated fermentation tank outside the orchard, where fermentation agents and straw fragments are added by weight. The tank is then covered with plastic film for anaerobic fermentation for 30 days, producing a semi-finished bio-organic fertilizer. The high temperature in the fermentation tank kills fruit fly eggs and pupae.

[0033] The fermentation inoculant includes Bacillus licheniformis and Trichoderma, and the ratio of the fermentation inoculant to straw fragments is 3:1.

[0034] In early March, a thorough spring pruning was carried out, with the entire orchard sprayed with a 5% lime sulfur solution, focusing on the trunks and ground surface. Dense branches were pruned to ensure ventilation and light penetration within the canopy, reducing the risk of white rot. Lime sulfur can disrupt the overwintering environment of pathogenic spores.

[0035] Step 2: Soil Microecological Reconstruction

[0036] Prepare customized organic slow-release fertilizer. Dig a 20cm deep circular trench along the drip line of the tree canopy, apply 5kg of slow-release fertilizer per tree, cover with soil, and then drip irrigate to retain moisture and promote the activation of the microbial agent.

[0037] The organic slow-release fertilizer formula is as follows: 20-30 parts bayberry residue, 10-15 parts rapeseed cake, 1 part microbial inoculant, 10-12 parts maifanite powder, and 5-8 parts lemongrass extract residue. After fermentation, the bayberry residue provides polysaccharides and decomposes to produce humic acid, enhancing water and fertilizer retention. The rapeseed cake decomposes to produce amino acids. The microbial inoculant contains silicate bacteria that solubilize potassium and fix nitrogen. The maifanite powder improves soil aggregate structure, and the lemongrass extract residue repels underground pests.

[0038] Step 3: Co-processing of induction and deduction

[0039] Prepare food attractants for later use, and prepare repellents to spray on fruit surfaces to repel gall midges. The food attractants mimic the smell of fermenting fruit to lure and kill adult midges, while citronella oil interferes with the gall midges' olfactory localization and can prevent them from laying eggs.

[0040] The food attractant formula consists of 5% brown sugar, 5% homemade rice vinegar, 1% fruit flavoring, and 0.01% abamectin.

[0041] The repellent is prepared by diluting lemongrass juice with water at a ratio of 1:5.

[0042] Step 4: Intelligent monitoring of the trapping device

[0043] Deploy intelligent trapping devices, hanging 30 IoT traps per hectare, with built-in food attractants and equipped with infrared counters. The devices upload insect population data to the cloud platform in real time. When the daily killing rate exceeds 50 insects / device, an early warning is automatically triggered and the frequency of lemongrass juice spraying is increased.

[0044] Step 5: Synergistic Effect Processing

[0045] For high-value varieties, single-plant insect-proof nets with a 40-mesh mesh are erected 15 days before maturity to prevent fruit flies from laying eggs. A pollution-free flower-thinning agent is sprayed during flowering to reduce redundant flowers and fruits and lower nutrient competition. The flower-thinning agent is of the ammonium acetate type. Orchard sanitation, soil improvement, and attractant application are implemented in three stages according to seasonal sequence, creating a synergistic effect. Fallen fruit is converted into organic fertilizer, achieving material recycling within the orchard.

[0046] The effectiveness of the present invention is verified through comparative experiments.

[0047] 1. The experimental site was a bayberry planting base in Zhejiang Province; the experimental area was 5 mu per group, and the soil conditions were the same; the experimental period was from March to June 2025.

[0048] 2. Experimental grouping and treatment methods

[0049]

[0050] The key monitoring indicator data are as follows;

[0051] Note: The data are the mean ± standard deviation of three simulated repeated experiments. The insect-infested fruit rate was calculated from 500 fruits randomly sampled during the harvest period.

[0052] As shown above, the insect-infested fruit rate in the invention group was significantly lower than that in the traditional group and all single-factor groups, proving that the synergistic effect of orchard sanitation, soil improvement, and attractants produced a multiplier effect. The cost per mu (unit of land area) for this invention is 210 yuan, which is lower than that of traditional control methods, mainly due to a 90% reduction in pesticide use and the recycling of waste, resulting in a cost advantage.

[0053] This invention significantly reduces the insect population by using two-stage field clearing and biological fermentation to kill pupae; it enhances soil microbial resistance through soil improvement, thereby increasing soil organic matter and reducing the incidence of onion disease; it attracts and kills adult insects and blocks egg laying through the dual interference of intelligent traps and repellents; and it achieves material recycling by converting waste into bio-fertilizer.

[0054] The high-quality fruit rate of this invention group is 91.5%, while that of the traditional group is 62.1%. Based on the market price of 30 yuan / kg for high-quality bayberries and 15 yuan / kg for ordinary bayberries, the increased income per mu (unit of land area) exceeds 5000 yuan. No pesticides were detected, meeting green standards.

[0055] This invention achieves improved pest control, zero use of chemical pesticides, and doubled planting benefits through spatiotemporal technological collaboration and ecological cycle design, providing a standardized solution for green production of bayberries.

[0056] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
