Special Issue Information

Dear Colleagues,

Medicinal plants are an integral part of ecosystem service for humankind and represent one of the most important bioresources in our planet, in which nature's ability is fully unlocked to prevent/treat human diseases. In order to avoid over-exploitation of wild medicinal plant resourses and achieve the sustainable utilization of medicinal taxa, much more research and investment are urgently needed in the domestication, cultivation and breeding of medicinal plants. The globalization of traditional medicine and ethnomedicine is accelerating; however, in order to protect the rights and interests of consumers and ensure a safe use of medicinally agricultural products, it is imperative to strengthen identification and quality control research. Particularly, since the outbreak and spread of COVID-19 in December 2019, these have gained more recognition of their unique values in prevention and treatment of epidemic diseases. Today, considerable studies are focused on the quality evaluation of herbal medicines, which, however, cannot meet the growing demand for drug safety if problems such as pesticide residues and heavy metal contamination cannot be effectively tackled. Hence, the eligible medicinal plant cultivation pattern should be actively explored so as to solve the quality problems of herbal medicines from the source and sustainably provide quality products. In improving herbal medicine quality, the theory and methods of good agriculture practice (GAP), ecological cultivation, plant pharmacophylogeny, and plant protection of medicinal plants hold great promise.

This Special Issue aims to reflect the current progress in planting production, plant protection, and identification and quality control of medicinally agricultural products. The situation and characteristics of artificially cultivated medicinal plants will be reported, which can be compared with wild-harvested ones, and identification/authentication and quality control/enhancement of diverse medicinally agricultural products via different methods will be scrutinized and elaborated.

This Special Issue especially welcomes research based on omics and high-throughput technology, as well as the exploration of multidisciplinary technology combination.

We welcome submissions of different types of manuscripts including original research papers, reviews, and methods, focusing on, but not limited to, the following topics:

  1. Advances and challenges in medicinal plant breeding, cultivation and planting production;
  2. Production of bioactive plant secondary metabolites through in vitro and in vivo technologies;
  3. Physical, chemical and biological methods for the identification/authentication of medicinal crops and medicinally agricultural products;
  4. Identification of genes and compounds with agronomical/medicinal relevance in cultivated medicinal plants;
  5. Quality control and improvement of medicinal crops and medicinally agricultural products;
  6. Implementation of good agriculture practice, ecological agriculture and pharmacophylogeny in medicinal plant production;
  7. Advances in disease epidemology, plant pathology, and integrated pest management in sustainable medicinal plants production.

Nitrogen fertilizer is the most frequently used fertilizer in the cultivation of medicinal plants, and has a significant contribution to their yields and quality. Yet, there is biased and excessive N application in medicinal crops. This study aims to quantitatively analyze the recommended N application concentrations for diverse medicinal species and disentangle the intricate relationships between soil fertility, N application rate (NAR), and the quality/yield of medicinal crops. We first characterized 179 medicinal species and 7 classes of phytometabolites therein, including terpenoids, flavonoids, phenylpropanoids, phenolics, alkaloids, etc., reported during the past three decades from the phylogenetic and spatial perspectives. The relationships between soil fertility, NAR, and medicinal crops were then subjected to statistical analyses. The pharmaco-phylogenetic and geographic distributions of NAR suggest that the impact of ecological/environmental factors on the N demand of medicinal plants was much greater than that of genetic endowments. We found that different medicinal species were distinct in N demand, which is related to soil fertility levels in different production areas. The NAR reported by China, 215.6 ± 18.6 kg/ha, was higher than that of other countries (152.2 ± 20.3 kg/ha; p = 0.023). Moderate N application generally increases the yield and phytometabolite content of medicinal crops, but excessive N application has the opposite effect. It is necessary to plan N concentration and formula fertilization on a case-by-case basis and with reference to empirical research. Our results provide baseline information and references for the rational application of N fertilizer in the precision agriculture of medicinal crops. Full article

The intelligent control of precision planting can detect and regulate the operation quality of the planter in real time, which plays an important role in improving the operation quality of the planter and the yield of the corn. In this paper, the control system of a corn precision planter is designed to realize the operating quality monitoring and electric driving of the seed-metering device. The planting quality is calculated by the time interval between the neighboring falling seeds, instead of the plant spacing, to improve the operational efficiency of the system. At the same time, the forward speed of the planter is obtained by radar, which is used to accurately match the speed of the seed-metering device with the forward speed of the planter. The velocity error of the radar is analyzed, and the relevant relationship of the radar output frequency and forward speed is established. Comparative test results of this system and the JPS-12 test bench show that the detection performance of the system is reliable, and the maximum detection error of the quality parameters is less than 2.88%. Field experiments were carried out to verify the operational performance of the control system. Two speed sensors, radar and GPS, were chosen to study the effect of speed measuring on the performance of the control system. We found that speed measuring has a significant effect on planting performance. The qualified parameters of radar were significantly higher than those of GPS, at a forward speed of 6–12 km/h. The qualification feeding index (QFI) of radar was 0.51%, 0.67%, and 2.05% higher than that of GPS at speeds of 6, 8, 10, and 12 km/h. The precision index (PREC) of radar was 17.60%, 5.44%, 16.81%, and 17.30% lower than that of GPS. Therefore, the control system based on the radar speed measurement developed in this paper can significantly improve the operating quality of the planter. Full article
