“…The results of the study showed that the improved method of producing seedlings from cuttings could increase the survival rate of pumpkins to 98%. Fu et al [41] also found that the current vegetable cutting method or single-bead cutting method is used to produce seedlings, which requires a lot of time and manual seedling grasping. This method of cutting technology has low efficiency rates.…”

Cyclocarya paliurus is a species with high economic, horticultural, and medicinal value. C. paliurus grows faster than other plants, increasing the demand for propagation through leaf and stem cuttings to produce seedlings. However, this species requires pre-control of environmental factors such as high temperatures (25–30 °C), humidity (80–90%), and specific light (2000 to 3000 lux) intensity levels during the cutting and seedling production process. However, it is difficult to predict suitable environments for the growth of C. paliurus. This study requires the use of big data technology to parameterize the method of intelligent control of the environment used in the process of making stakes and creating seedlings. Our main results were that an improved convolutional neural network and short long-term memory (LSTM) in big data technology were used with a new method, multipath hole convolution (MPCNN), to predict environmental factors in production of seedlings. Also, the research results show that the MPCNN and LSTM methods can accurately predict the necessary temperature, humidity, and light conditions in the production process of C. paliurus seedlings. For the prediction of environmental characteristics related to this species, the light characteristics have a high error distribution, but the method described here was able to accurately control this variation, with an error of less than 2%.

“…However, the high cost of these robots, the strict requirements for the agronomic traits of the scion and rootstock seedlings, and the complexity of their repairs are obstacles to their adoption in China [26]. China began researching grafting machines in the 1990s [27][28][29]. In 2005, China Agricultural University launched the 2JSZ-600 grafting robot, which used a doublearm bidirectional cutting mechanism.…”

The rising age of the population in rural China and the labor intensity of grafting have resulted in a decrease in the number of grafters and a subsequent increase in their wages. Manual grafting can no longer satisfy the increasing demand for watermelon-grafted transplanting; thus, machine grafting will be an effective alternative. In order to accelerate the implementation of machine grafting in China, a comparative analysis between the automatic grafting machine (model 2TJGQ-800) and traditional hand grafting was conducted. The reliability and feasibility of machine grafting were evaluated through a comprehensive evaluation of the production capacity and grafting seedling quality. This study focuses on the grafting application of watermelon plug-tray seedlings. The scion and rootstock seeds were sown on 9 November 2022. Grafting experiments using an automatic grafting machine, skilled workers, and ordinary workers were conducted with the root-pruned one-cotyledon grafting method on 24 November 2022. The results showed that the machine grafting had a high uniformity and grafting speed. The grafting speed of the grafting machine was 774 plant·h−1 and 1.65–2.55-fold higher than the hand grafting. With training, workers can improve their grafting speed, but it will still be slower than machine grafting. In addition, there was no significant difference in the grafting survival rate between the machine grafting and hand grafting. However, using machine grafting, the success rate decreased from 100% to 90.07% and the rootstock regrowth rate increased from 18.44% to 72.69%. Incomplete rootstock cutting, clip supply failure, and grafting drop failure are the three main factors that result in machine grafting failure. In conclusion, the grafting machine has advantages in terms of grafting speed and uniformity. Upon improving the accuracy of the cutting mechanism and grafting success rate, it will be adopted by commercial nurseries.

Grafting is a technique that involves attaching a rootstock to the aerial part of another genotype or species (scion), leading to improved crop performance and sustainable growth. The ability to tolerate abiotic stresses depends on cell membrane stability, a reduction in electrolyte leakage, and the species of scion and rootstock chosen. This external mechanism, grafting, serves as a beneficial tool in influencing crop performance by combining nutrient uptake and translocation to shoots, promoting sustainable plant growth, and enhancing the potential yield of both fruit and vegetable crops. Grafting helps to enhance crop production and improve the capacity of plants to utilize water when undergoing abiotic stress, particularly in genotypes that produce high yields upon rootstocks that are capable of decreasing the impact of drought stress on the shoot. The rootstock plays a pivotal role in establishing a grafted plant by forming a union between the graft and the rootstock. This process is characterized by its integrative, reciprocal nature, enabling plants to tolerate abiotic stress conditions. Grafting has been shown to alleviate the overproduction of lipid peroxidation and reactive oxygen species in the leaves and roots and enhance drought tolerance in plants by maintaining antioxidant enzyme activities and stress‐responsive gene expression. Phytohormones, such as cytokinin, auxin, and gibberellin, play a critical role in maintaining rootstock‐scion interactions. This review unveils the role of grafting in mitigating various environmental stressors, establishment of a robust graft junction, physiology of rootstock‐scion communication, the mechanism underlying rootstock influence, hormonal regulations and the utilization of agri‐bots in perfect healing and further cultivation of vegetable crops through grafting.
