Description

Technical Field

[0001] The invention relates to the technical field of oil-tea camellia cultivation, and in particular to a method for water vapor circulation and mildew prevention of oil-tea camellia skin-lift grafted rootstock and scion. Background Art

[0002] The field of tea oil cultivation technology is mainly used for the production of tea oil. The cultivation process needs to consider many factors such as the growth conditions of trees, grafting techniques, and pest and disease control, which helps to improve the survival rate of tea oil trees, enhance production efficiency, and ensure the yield and quality of tea oil.

[0003] The moisture circulation and mildew prevention method of the oil-tea grafted rootstock and scion is aimed at improving the grafting survival rate by optimizing the moisture circulation and preventing mildew at the grafting site. The purpose is to ensure the healthy growth of the grafting site and prevent mildew problems caused by excessive humidity or poor ventilation, thereby promoting the smooth fusion and stable growth of the grafted plants, improving the grafting survival rate, reducing the effect of fungal infection, and increasing the success rate of oil-tea cultivation.

[0004] Traditional grafting methods have deficiencies in water vapor regulation and shading. The grafted site becomes moldy due to improper humidity control, affecting the grafting survival rate. The unobstructed water vapor channel cannot be fully considered, resulting in water retention at the grafted site, causing healing barriers between the rootstock and the scion, and causing rot at the grafted site. The light intensity at the grafted site cannot be accurately controlled, causing the grafted site to be affected by excessive light and poor ventilation, reducing the grafting survival rate. The moisturizing material cannot be gradually removed according to the healing situation, resulting in an unbalanced water vapor circulation, affecting the long-term stability after grafting, reducing the success rate of grafting, and increasing the risk of plant fungal infection. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a method for moisture circulation and mildew prevention of oil-tea-tea-lift grafted rootstock and scion.

Based on the growth status of the main trunk of the tea oil tree, give priority to plants with an annual oil yield lower than the standard and inferior plants accounting for more than 50% of the whole forest. Cut off part of the trunk, use the skin grafting method to graft the improved tea oil tree spike buds, tie and fix the spike buds to form a grafted body.

[0008] Step 2: Based on the grafted combination, a length of 80 cm to 100 cm is reserved on the trunk after trunk cutting, and a grafting knife is used to carve a notch below the phloem of the rootstock to ensure the smoothness of the water vapor channel, and the notch treatment is completed in combination with the characteristics of the rootstock to generate a water vapor channel structure;

[0009] Step 3: Based on the water vapor channel structure, fix straws on both sides of the rootstock to ensure that the position of the straws has the best effect on the passage of water vapor, put on a moisturizing bag for sealing, and add kraft paper to the outer layer of the moisturizing bag to block the sun's direct rays, so as to generate a water vapor control shading system;

[0024] Based on the straw fixing structure, a moisturizing bag is put on, and a tight sealing method is adopted to make the bag opening completely cover the grafting part and the straw. The sealing effect of the moisturizing bag is reinforced by bundling, and whether there is looseness or leakage is checked to generate a moisturizing bag sealing structure.

[0025] Based on the sealing structure of the moisturizing bag, a kraft paper shading layer is used to cover the moisturizing bag along the light direction of the grafted part, and the angle of the shading layer is precisely adjusted to completely block direct light. The shading effect is verified and airtightness is ensured to generate a water vapor controlled shading system.

The design of the water vapor regulating shading system enables the grafting part to avoid direct sunlight while keeping it moist, thereby enhancing the grafting survival rate. The water vapor channel structure after grafting optimizes the water vapor circulation of the rootstock through the reasonable arrangement of the straw, avoids the situation of local over-humidification, and contributes to the stable growth of the grafted combination. By gradually removing the straw and the moisturizing bag, the rootstock and the scion can heal naturally, thereby ensuring the long-term growth stability of the scion, improving the success rate of grafting, reducing the risk of fungal infection, ensuring the smooth fusion of the scion and the rootstock, and improving the production efficiency and quality of oil tea.

[0051] The specific steps for generating a grafted conjugate are:

[0052] Based on the selection criteria for oil tea forests, screening was conducted with forests aged 15 to 30 years. By observing the growth status of the plants, confirming the annual yield below the standard and measuring the proportion of inferior plants, part of the main trunk was cut to generate the initial main trunk;

[0053] Based on the initial trunk, the length of the trunk after cutting is measured to determine the cross-sectional area of ​​80cm to 100cm. The oil-tea tree spikelets are grafted to the selected position using the skin grafting technique and tied to form a grafted trunk combination.

[0054] Based on the grafted trunk combination, the tightness of the binding and the fit of the spike buds are checked to ensure the close combination of the spike buds and the trunk, the overall stability is reviewed and the grafting operation is confirmed to generate the grafted combination;

[0055] Based on the selection criteria of oil tea forest, a specific oil tea forest screening algorithm is used to screen plants with a forest age of 15 to 30 years. The annual oil yield is measured through the annual yield measurement module of oil tea trees. The plants with annual yields below the standard are determined by calculating the difference between the annual yield of each oil tea tree and the standard annual yield. The inferior plant ratio calculation function is applied to the plant detection data, and the inferior plant ratio is generated by accumulating the number of inferior plants and the total number of plants. The trunk detection algorithm is used to intercept part of the trunk and confirm the trunk attributes to generate the initial trunk.

[0056] Based on the initial trunk, the trunk length measurement function is used to measure the length of the trunk after cutting. The length area of ​​the trunk is determined by inputting the coordinates of the measurement points of the trunk, and the coordinates are compared with the preset parameters of 80cm to 100cm. The skin-lifting operation function is used to pass the grafting operation parameters of the skin-lifting to the interface, and the spike bud grafting submodule is called. The coordinate data of the improved spike bud is input into the spike bud access point to generate a combination of the spike bud and the cross-section position. The binding pressure value and binding tightness are set by the binding parameters to generate a grafted trunk combination.

[0057] Based on the grafted trunk combination, the binding detection module is used to detect the tightness of the binding, and the fit of the spike bud is detected by setting the contact area parameters between the spike bud and the trunk. The stability of the grafting point is checked using the combination stability analysis function, and the review module is called to confirm the completion of the grafting operation to generate a grafted combination.

[0061] Based on the preliminary structure of the water vapor channel, the smoothness of the water vapor channel is manually checked, and the angle and depth of the notch are gradually adjusted to ensure effective water vapor circulation. After review, it is confirmed to be complete and the water vapor channel structure is generated;

[0062] Based on the grafted body, the trunk length measurement algorithm is used to measure the trunk length, the input length range is 80cm to 100cm, the notch position is calibrated by the marking algorithm, the incision depth control function is called to set the incision depth of the rootstock phloem, the notch angle control value is input as 45 degrees to 60 degrees, and the grafting knife cutting module is used to calculate the coordinate difference between the notch and the trunk to generate the notch position mark;

[0063] Based on the marking of the notch part, the notch depth and width adjustment algorithm is used to adjust the width and depth of the notch. The ventilation coefficient of the channel is set by inputting the water vapor circulation parameter value. The segmented carving module is called to perform cutting operations according to the preset width range. The input notch length range is 5mm to 10mm. The step-by-step control function is used to carve segment by segment. The notch shape calculation formula is used to adjust the notch shape in real time to generate the preliminary structure of the water vapor channel.

[0064] Based on the preliminary structure of the water vapor channel, a manual inspection algorithm was used to check the smoothness of the water vapor channel. The water vapor flow parameter value was input from 0.5 to 1.5 m / s. The angle and depth of the notch were gradually adjusted through the real-time adjustment module. The notch angle detection function was used to review the water vapor flow path in the channel to generate the water vapor channel structure.

The straw fixing module is used to set the binding material parameter to a tension of 3N to 5N. The binding material is used to firmly fix the straw on the rootstock surface through the tension control function. The degree of fixation is verified to generate a straw fixing structure.

[0070] Based on the fixed structure of the straw, the moisturizing bag set algorithm is used to cover the grafting part and the straw with the moisturizing bag. The sealing detection module is used to detect the tightness of the seal and adjust the tightness of the bundling material in real time. The coverage range is controlled by setting the ratio of the moisturizing bag length to the exposed distance of the straw. The sealing inspection module is called to check whether the moisturizing bag is loose or leaking, and the moisturizing bag sealing structure is generated.

[0071] Based on the sealing structure of the moisturizing bag, a shading layer covering algorithm is used to accurately cover the light angle of the kraft paper shading layer. The light angle data is input through the light sensor module, and the shading layer angle is set to 45 degrees to 90 degrees. The shading layer angle adjustment module is used to adjust the contact area between the shading layer and the moisturizing bag. The shading covering function is used to set the coverage ratio of the shading layer and the moisturizing bag to 80% to 100%.

The growth area parameters of the grafting site are input, and the thickness of the callus tissue is measured by using a thickness measurement function. The thickness measurement range is set to 0.5 mm to 2 mm. The distribution uniformity of the callus tissue is checked by the distribution detection module to generate the callus tissue observation results.

[0077] Based on the callus observation results, the color of the callus was detected using a color analysis algorithm. The color difference parameter range of the healing area was input from 0 to 255. The healing area was gradually analyzed through the tissue analysis module. The color difference comparison function was called to compare the color difference of the growth state with that of the tissue before and after grafting. The color difference value was recorded and the color change parameter value was input into the observation result database to generate the callus color analysis.

[0078] Based on the color analysis of callus tissue, the survival rate of the grafted part is judged by the survival rate judgment algorithm. The input survival rate judgment standard is in the range of 85% to 100%. The recovery of callus tissue is analyzed through the recovery analysis module in combination with the water vapor regulation record data. The data recording module is used to record the relevant healing data, and the healing results are summarized through the induction function to generate the callus tissue status.

[0079] The specific steps to generate the exposed healing state are:
