“…In this study, the PN decreased with the increase of phenolic acid concentration at 0X-3.0X treatment. These results were similar to those of a previous study in which at 0X-1.0X phenolic acid concentrations, with an increase in the concentration of phenolic acids, the poplar PN also significantly decreased (Li et al 2018. Some scholars use Hoagland's nutrient solution for cultivation.…”

“…Both stomatal and nonstomatal limitation affected photosynthetic rate under phenolic acids stress (Fu et al 2019). In the present study, with the increase in the concentration of phenolic acids, the PN decreased and the Ci increased, indicating that the main cause of this phenomenon involves stomatal factors (Li et al 2018). Moreover, at 0X-1.5X phenolic acids concentrations and with further increase in the concentration of phenolic acids (when both the PN and Ci decreased, and the Ls increased), the degree of stomatal opening gradually decreased, and the CO2 supply was continuously blocked, which was similar to the results of Fu et al (2019).…”

“…Stomatal factors are also the main factors leading to reduced photosynthesis of poplar trees. However, the phenolic acid concentration in the study of Li et al (2018) was only 1.0X, so whether the results in response to a phenolic acid concentration of 1.5X would be similar to the results of this study needs to be further verified. In the present study, at concentrations from 1.5X-3.0X, the Ci increased with increasing phenolic acid concentration, whereas the P N, Ls, and gs decreased.…”

“…In the mid of April 2018, we established seven treatments, 0X, 0.5X, 1.0X, 1.5X, 2.0X, 2.5X, and 3.0X (see text table), based on the actual concentration of phenolic acids in the soil of a second-generation continuously cropped poplar plantation, which was used as the reference concentration (X) (Li et al 2018). Before the start of the test, the phenolic acids were sprayed onto each pot.…”

Barriers to continuous cropping of poplar plantations are closely related to the accumulation of phenolic acids in the soil. The purpose of this study was to explore the mechanism through which phenolic acid stress affects poplar productivity. The results showed that phenolic acids had a significant inhibitory effect on the photosynthesis of poplar. The inhibition of photosynthesis due to phenolic acids occurred mainly because, during electron transfer at the PSII reaction center, the primary quinone acceptor of PSII (QA) in the oxidized state was reduced, and excess light energy was lost in the form of heat dissipation; thus, poplar productivity decreased. At low phenolic acid concentrations (0X-1.5X), the activity of the PSII reaction center was temporarily inactivated, mainly because of stomatal limiting factors. At high phenolic acid concentrations (1.5X-3.0X), the PSII reaction centers were damaged, and photoinhibition occurred, mainly because of nonstomatal limiting factors.

“…The main reasons for the high nitrogen use efficiency and nitrogen uptake might be that photosynthesis increased nitrogen transport to cotton bolls and decreased litterfall 27,28 . Regardless of the FA application rate, the nitrogen uptake in the CRU treatments was higher than that in the Urea treatments.…”

A split-plot field experiment was conducted in 2018–2019 to study the effects of nitrogen fertilizer types and fulvic acid (FA) rates on soil nitrogen and cotton growth. The nitrogen fertilizers included controlled-release urea (CRU) and urea, which were applied combined with three FA rates (90, 180 and 270 kg ha-1). The main plot was the nitrogen fertilizer type, and the subplot was the FA rate. The results showed that the lint yield of the FA180 treatment was 5.2–8.6% higher than the FA90 and FA270 treatments. Moreover, moderate FA application markedly improved the cotton leaf SPAD value (chlorophyll relative value), photosynthesis and chlorophyll fluorescence parameters compared with low and high FA rates. Replacing urea with CRU significantly increased the soil inorganic nitrogen and nitrogen use efficiency and also improved cotton fiber quality parameters. Meanwhile, the boll weight and seed yield of the CRU treatments were 1.5–8.4% and 3.3–19.1% higher, respectively, than the urea treatments. The interaction between nitrogen type and FA rate had a positive effect on cotton growth. Thus, the application of CRU combined with 180 kg ha-1 FA on cotton can not only improve the fiber quality and delay leaf senescence but also increase the yield and economic benefit.
