“…Chlorophyll content and the photosynthetic rate increased, with significantly higher activity of photosynthetic enzymes, including NADP-malate dehydrogenase (NADP-MDH), phosphoenolpyruvate carboxylase (PEPC), and ribulose-1,5-bisphosphate carboxylase (RuBPC) under FT compared to CK. Sugarcane height, stem diameter, single stem weight, effective stem number, and yield significantly increased under FT compared to that under CK [46,50]. Our results revealed that the sugarcane root index, SSR, tillering rate, and yield of FT in newly planted and ratoon sugarcane were significantly higher than those of the control treatment.…”

“…Zhu et al [46] found the contents of organic matter, total nitrogen, available phosphorus, and available potassium were higher in soil under FT than those under conventional tillage, which indicates the activation of soil nutrients was greater in FT soil. In this study, FT significantly affected AN, AK, and AP throughout the sugarcane growth period, as compared with conventional tillage.…”

“…FT breaks the hardpan under the plow layer and creates a soil layer that is suspended and loosened, which leads to more favorable hydrothermal conditions, increases the availability of nutrients, water, and oxygen, and thus enhances microbial activities, thereby improving plant photosynthetic efficiency and crop yield [43][44][45][46]. FT has the characteristics of deep tillage and rotary grinding, which increase soil porosity and decrease soil bulk density [20,41,47].…”

“…In this study, soil physical qualities, such as soil bulk density and porosity, were improved by FT. There were significant differences in the soil bulk density and porosity between the conventional and FT. A reduction in soil bulk density, an increase in soil porosity and water storage, and an improvement in available N and P after FT treatment indicated that FT could play an active role in the storage of soil nutrients [20,[44][45][46]50].…”

Sugarcane yield in China is low because of the shallow A-horizon soil layer, or as it is commonly called by farmers, the “plow soil layer”, as well as low soil organic matter and fertilizer utilization efficiency. Fenlong-ridging deep tillage (FT), also called vertical rotary tillage, and amendment with biochar have been shown to improve soil quality and crop yield. In this study, field trials were conducted with newly planted and ratoon sugarcane to evaluate the effectiveness of FT, together with amendment with biochar and nitrogen fertilization, to improve sugarcane yield. The treatments were conventional tillage with chemical fertilizer without biochar (CT-CF, which was the control of this experiment), FT with chemical fertilizer without biochar (FT-CF), conventional tillage with chemical fertilizer mixed with biochar (CT-CFB), and FT with chemical fertilizer mixed with biochar (FT-CFB). FT-CFB treatment presented higher soil porosity, as well as higher contents of available N, P, K, total N, and organic matter, and lower soil bulk density. Similarly, results showed that FT-CFB presented higher sugarcane root fresh and dry weights, higher germination percentage, higher tiller number, and higher yield with statistically significant differences among treatments for both newly planted and ratoon sugarcane plants. Significant interactions between biochar and FT were observed for these crop traits. The interactions of FT and amendment with biochar improved the soil’s physical and chemical properties and increased the available nutrients, resulting in improved root growth and sugarcane yield. The statistical results of the present study imply that Fenlong-ridging deep tillage combined with chemical fertilizer mixed with biochar (FT-CFB) application is a new promising farm management practice for improving the soil’s physical and chemical properties and root growth, increasing total yield in China’s sugarcane belt area.

Soil compaction and resource competition are bottlenecks in the improvement of sugarcane productivity in intercropping systems. Fenlong tillage improves crop yields by alleviating soil compaction and ensuring water supply. Wide‐narrow rows are an effective solution for light competition. An efficient intercropping system with Fenlong tillage technology as the core needs to be constructed. A two‐cycle field study was conducted to investigate the effects of planting methods [sole ratoon sugarcane (S) and ratoon sugarcane‐soybean intercropping (I)] combined with tillage [conventional rotary tillage (RT), Fenlong tillage “145” mode (FL145)] on soil physical characteristics, photosynthesis, and growth of ratoon sugarcane, as well as crop yields. For the ratoon sugarcane, compared to RT‐I, FL145‐I decreased bulk density and increased porosity in the 0–40 cm soil layer. Root growth parameters were improved under FL145‐I in the 0–20 cm soil layer. FL145‐I positively affected the stomatal conductance, causing increases in the net photosynthetic and transpiration rates. The increased leaf area index, chlorophyll relative content, and photosynthesis under FL145‐I caused higher dry matter accumulation. The increased single stalk weight under FL145‐I resulted in 17.13%–22.55% higher stalk yield with similar quality. Intercropping under the wide‐narrow row planting pattern had no negative effects on the growth and stalk yield of ratoon sugarcane. For the soybean, compared to RT‐I, the increased 100‐seed weight under FL145‐I resulted in 11.14% higher seed yield with similar quality. Therefore, FL145‐I presents a promising and novel management practice for sustainably increasing ratoon sugarcane productivity in China.

Conservation Tillage in Medicinal Plant Cultivation in China: What, Why, and How

Ecological cultivation is a promising regime for medicinal plant production. For a long time, unreasonable farming methods have threatened soil health and medicinal agriculture and restricted the sustainable development of ecological agriculture for medicinal plants. However, there is a lack of comprehensive discourse and discussion about the pros and cons of different tillage regimes. Here, the research trend and application prospects of no-tillage (NT) are comprehensively reviewed, and the ecological benefits, challenges, and opportunities of the NT system in ecological agriculture of medicinal plants are scrutinized, aiming to call for an about-face in the sustainable conservation and utilization of both phytomedicine resources and agricultural/ecological resources. An exhaustive literature search in PubMed, Bing, Scopus, and CNKI was performed to outline the research trend in conservation tillage and medicinal plants during the recent four decades. The application of NT has a long history and can reduce tillage frequency and intensity and protect soil from erosion and deterioration. NT is often combined with organic mulch to significantly reduce soil disturbance. NT and stover mulching have the advantages of saving manpower and resources and improving soil quality, crop yield, and quality. The ecological and economic benefits of NT in long-term medicinal plant cultivation could be prominent. In developing medicinal plant cultivation, competing with food crops should be avoided as much as possible, and the impact on the production of major grain crops should be minimized. Therefore, the full utilization of soil resources in forests, mountains, and wasteland is advocated, and sustainable soil utilization is the core issue in the process of land reclamation. NT and stover mulching not only inherit the traditional concept of “natural farming”, conform to the basic laws of ecology, as well as the growth characteristics of medicinal plants, but also protect the ecological environment of the production area. It would become the core strategy of ecological agriculture for medicinal plants. Our summary and discussions would help propose countermeasures to popularize NT and organic mulch, promote relevant research and scientific allocation of resources, and adapt to local conditions to achieve precise management and harmonize conservation and production of medicinal plants.
