[0022] As an important vegetable crop, tomatoes are widely planted globally. To increase the yield and quality of tomatoes, growers continuously try various planting techniques. Among them, grafting technology has attracted much attention due to its remarkable disease resistance and yield increase effect. Tomato grafting technology not only depends on excellent rootstock and scion varieties but also on efficient grafting equipment and scientific grafting methods.

[0023] Tomato grafting technology utilizes the characteristic that the rootstock has high resistance to soil-borne diseases, and grafts the scion with excellent traits onto the rootstock to avoid the occurrence of soil-borne diseases such as bacterial wilt and root rot. Through grafting technology, not only can the disease resistance of tomatoes be improved, but also their stress resistance can be enhanced, and the yield and quality can be increased.

[0024] Tomato grafting technology mainly includes the following key links:

[0025] Grafting preparation: Select suitable rootstock and scion varieties, and carry out seed treatment and germination promotion.

[0026] Grafting method: Common grafting methods include cleft grafting, sleeve grafting, needle grafting, etc. Among them, needle grafting is widely used because of its simple operation, fast grafting speed and high survival rate.

[0027] Post-grafting management: Post-grafting management includes control of temperature, humidity, light and pest and disease control.

[0028] Tomato double-root-cutting and double-head grafting technology is an innovative grafting method. By simultaneously cutting the hypocotyl of the rootstock and re-cutting and rooting, the neat growth trend and yield increase effect of grafted seedlings are achieved.

[0029] The tomato double-root cutting and double-head grafting technology is based on the traditional grafting method. By cutting off the hypocotyl of the rootstock and re-rooting, the grafted seedlings can grow neatly and increase production. This technology has the following advantages:

[0030] Uniform growth: After the rootstock is rooted, the grafted seedlings grow evenly, which is conducive to mechanized operation.

[0031] The grafting site is not prone to water accumulation: The grafting site is not prone to water accumulation, which ensures that the grafting site has sufficient oxygen and promotes healing.

[0032] Save scion seeds: Each scion can be grafted with 2 double-headed seedlings, saving 50% of scion seeds.

[0033] Increase yield: The root system of the grafted seedlings is well developed and they grow vigorously in the field. The yield per mu can be increased by 8% to 10% compared with conventional grafted seedlings.

[0034] Equipment and technical points for double-root cutting and double-head grafting of tomatoes

[0035] Rootstock selection:

[0036] It should have corresponding resistance and affinity, and be required to grow vigorously, easily produce air and roots, and have long internodes.

[0037] The southern region mainly uses rootstock varieties that are resistant to bacterial wilt, such as Zhejiang rootstock and Gui rootstock; the northern region mainly uses rootstock varieties that are resistant to root rot, such as Jinpeng rootstock and Jiulv 787.

[0038] Disinfection of facilities and equipment:

[0039] Disinfect the greenhouse, seedbed and ground before starting seedling cultivation.

[0040] Potassium permanganate + formaldehyde disinfection method is commonly used for greenhouse disinfection. For every 1,000 cubic meters of greenhouse, 0.562 kg of potassium permanganate, 0.562 liters of formaldehyde, and 2.811 kg of boiling water are mixed to produce smoke. The greenhouse is sealed for 24 to 48 hours for disinfection, and it can be used after the smell has dissipated.

[0041] Seedbeds and ground disinfection usually involve spraying chemical pesticides, mainly to kill insect eggs and stubborn pathogens. The dosage is 2 to 3 times the normal dosage for seedlings.

[0042] Matrix selection:

[0043] Using peat as the basic raw material, the matrix product is required to be stable in nature and small in particle size (0-6 mm).

[0044] Other ingredients can be added selectively according to needs. Generally, peat, vermiculite and perlite are mixed. The mixing ratio varies slightly in different regions and different technical systems. Common mixing ratios (volume ratios) are 7:2:1, 4:2:1, 6:3:1, etc.

[0045] The substrate for covering is different from the substrate for sowing, and it is necessary to reduce the proportion of peat or even not use peat at all. After filling the mixed substrate into the plug tray, gently level it to avoid excessive vibration affecting the water permeability and air permeability of the substrate.

[0046] Management before sowing and grafting:

[0047] The sowing time of the rootstock and scion should be determined according to the growth rate to ensure that the seedling age and stem diameter of the rootstock and scion are suitable for grafting. Generally, the scion is sown 2 - 4 days earlier than the rootstock.

[0048] Generally, a 72 - cell standard plug tray is used for sowing the rootstock, and a 72 - cell or 105 - cell plug tray is used for sowing the scion. Sow 1 seed in each hole, and place the seed in the center of the hole. The sowing depth is 0.8 - 1.0 cm. After sowing, cover the substrate and water appropriately.

[0049] After sowing the rootstock and scion, put them into the germination chamber or directly into the seedbed for germination. Keep the germination temperature at 28 - 32°C. After the seeds germinate, the night temperature can be reduced to 20 - 23°C.

[0050] From cotyledon stage to 1 - leaf stage: The management of seedlings mainly focuses on controlling the elongation of the hypocotyl. Strengthen the light, control the substrate humidity, and keep the substrate water content below 70%.

[0051] At 1 - 2 - leaf stage: It is an important period for the roots of the seedlings to form a cluster. Efforts should be made to promote root development, keep the substrate moist and not form dry lumps; at the same time, attention should also be paid to the supply of fertilizer and water to avoid fertilizer deficiency and keep the leaf color dark green.

[0052] At 3 - 4 - leaf stage: Hardening of seedlings should be strengthened, mainly with strong light exercise. Appropriately reduce the temperature in the greenhouse, increase the day - night temperature difference. Control the day temperature at 25 - 28°C and the night temperature at 15 - 18°C. Control the substrate water content at 60% - 65% to promote the strong growth of seedlings.

[0053] Key points of grafting technology:

[0054] The grafting time should be selected on a sunny day, avoiding grafting on rainy or cloudy days to ensure that the temperature in the seedbed is easy to control after grafting.

[0055] Before grafting, the grafted seedlings should be properly hardened to make the seedlings adapt to the environmental conditions after grafting.

[0056] During grafting, ensure that the cut surfaces of the rootstock and scion are flat and smooth to avoid damaging the tissue of the seedlings.

[0057] After grafting, immediately put the grafted seedlings into the seedbed and cover them with a moisture - retaining film to maintain suitable temperature and humidity conditions in the seedbed.

[0058] Management after grafting:

[0059] After grafting, the temperature and humidity conditions in the seedbed should be strictly controlled to avoid grafting failure caused by too high or too low temperature.

[0060] Within 3 days after grafting, the relative humidity in the seedbed should be maintained above 95% to promote the healing of the grafting site.

[0061] About 7 days after grafting, the humidity in the seedbed should be gradually reduced and the ventilation volume increased to avoid excessive growth of the seedlings.

[0062] About 15 days after grafting, the survival status of the grafted seedlings should be checked, and the ungrafted seedlings should be removed in time.

[0063] The tomato double-root-cutting and double-head grafting equipment is an important tool for realizing the tomato double-root-cutting and double-head grafting technology. The following is the relevant introduction of the tomato double-root-cutting and double-head grafting equipment:

[0064] Automated grafting equipment: This equipment adopts an automated control system, which can realize the automatic cutting, automatic alignment and automatic fixation of the rootstock and scion. By adjusting the parameters of the equipment, it can adapt to tomato seedlings with different diameters, improving the efficiency and accuracy of grafting.

[0065] Multifunctional grafting machine: The multifunctional grafting machine is a device that integrates cutting, alignment, fixation and packaging. This equipment can process multiple tomato seedlings at the same time, greatly improving the efficiency of grafting. In addition, this equipment also has multiple functions, such as automatic cleaning, automatic disinfection, etc., ensuring the hygiene and quality of the grafted seedlings.

[0066] Handheld grafting tool: The handheld grafting tool is a device suitable for small-scale tomato grafting. This tool has the advantages of simple operation and convenient carrying, and can meet the needs of farmers for tomato grafting in the fields.

[0067] The sleeve grafting equipment is a device that connects the rootstock and scion using a sleeve. This equipment has the advantages of simple operation, fast grafting speed and high survival rate. The following is the relevant introduction of the sleeve grafting equipment:

[0068] Sleeve selection: The sleeve should be made of materials with soft texture, good elasticity and corrosion resistance. Common sleeve materials include plastics, rubbers, etc. The diameter of the sleeve should be selected according to the diameters of the rootstock and scion to ensure that the sleeve can tightly wrap the rootstock and scion.

[0069] Grafting method: The sleeve grafting method is relatively simple. First, align the cut surfaces of the rootstock and scion, and then put the sleeve on the cut surface so that the sleeve tightly wraps the rootstock and scion. After grafting, the grafted seedlings should be placed in the seedbed and covered with a moisture-keeping film to maintain suitable temperature and humidity conditions in the seedbed.

[0070] Device features: The sleeve grafting device has the advantages of simple operation, fast grafting speed, and high survival rate. In addition, the device can also adapt to tomato seedlings with different diameters, improving the flexibility and accuracy of grafting.

[0071] The mechanical grafting device is a device that uses mechanical principles to connect the rootstock and scion. This device has the advantages of a compact structure, simple operation, and high grafting efficiency. The following is the relevant introduction of the mechanical grafting device:

[0072] Working principle: The mechanical grafting device realizes the cutting, alignment, and fixation of the rootstock and scion through a mechanical structure. This device usually includes parts such as a cutting device, an alignment device, and a fixation device. The cutting device is used to cut the incisions of the rootstock and scion; the alignment device is used to align the incisions of the rootstock and scion; the fixation device is used to fix the rootstock and scion together.

[0073] Device features: The mechanical grafting device has the advantages of a compact structure, simple operation, and high grafting efficiency. In addition, the device can also adapt to tomato seedlings with different diameters, improving the flexibility and accuracy of grafting. However, this device has relatively high requirements for the operator's skills and requires a certain amount of mechanical knowledge and operating skills.
