ABSTRACT Increasing nitrogen use efficiency in agricultural fields is crucial for sustainable development. In a 2‐year greenhouse study, we compared two methods, subsurface irrigation with ceramic emitters (SICE) and drip (SDI), to evaluate their effects on soil moisture distribution, photosynthetic plant stoichiometry. The results showed that SICE can reduce the nitrate content by approximately 20% while maintaining at 70%–80%, improving melon yield. Under optimal yield treatment (applying 60.67 kg of fertilizer per hectare), SDI, increased 8%, water productivity 13%, absorption 4% 3%. addition, analysing stoichiometric characteristics different application rates growth stages under found main reason increase was coupled effect need plants maintain internal balance.

Abstract Tomato root soil quality and microbial community composition are important for improving fruit quality. However, the effect of biochar amendment on tomato characteristics under greenhouse production has been insufficiently explored. In this study, bacterial communities in subjected to were analyzed using Illumina sequencing. The results showed that application increased available phosphorous soils, ranging from 49.37 52.02 mg kg −1 . Biochar greatly affected quality, such as lutein content (1.55 μg g ). potassium fruits was higher than nitrogen phosphorous, reaching 1.59 addition promoted abundance Bacteroidota, Actinobacteriota, Firmicutes at phylum level fruits. slightly reduced number Proteobacteria This study provides new insights into practical strategies promoting condition.

Optimizing planting density to improve growth, yield and resources use efficiencies of winter oilseed rape under ridge-furrow film mulching

Journal of Integrative Agriculture, Год журнала: 2024, Номер unknown

Ridge-furrow film mulching has been widely used as a water-saving and yield-increasing planting pattern in arid semiarid regions. Planting density is also vital important influencing factor of crop yield, the optimal will change different environments (such ridge-furrow mulching). How combination affect growth, physiology, water radiation use efficiencies winter oilseed rape not clear yet. Therefore, three-year (from 2017 to 2020) field experiment was conducted explore responses leaf chlorophyll content (LCC), net photosynthetic rate (Pn), area index (LAI), aboveground dry matter (ADM), root growth distribution, evapotranspiration (ET), efficiency (WUE) (RUE) patterns (F, with plastic over ridges; N, flat without mulching) densities (LD, 100,000 plants ha–1; MD, 150,000 HD, 200,000 ha–1). The results showed that F treatments obtained significant greater LCC, Pn, LAI ADM, stronger system than throughout whole rapeseed growing seasons. Winter MD had better physiological (LCC Pn) (LAI, taproot lateral root) conditions LD HD at late period after stem-elongation. Grain yield FMD greatest, 34.8–46.0%, 6.7–9.6%, 87.8–108.3%, 38.7–50.3%, 50.2–61.8% significantly FLD, FHD, NLD, NMD, NHD, respectively. Furthermore, consumed equivalent ET FLD 12.2–18.4%, 14.5–20.3%, 14.6–20.4% markedly lower NHD. Finally, WUE RUE were improved by 88.5–94.0% 29.0–41.8% comparison NHD (local conventional for rapeseed). In summary, favorable cultivation management strategy save water, increase improve resources utilization northwest China.

Supplementary irrigation with ceramic emitter promotes Platycladus orientalis growth by enhancing soil bacterial α diversity under extremely high-temperature

Agricultural Water Management, Год журнала: 2024, Номер 301, С. 108958 - 108958

Although afforestation plays a crucial role in reducing global warming, the survival of forests is increasingly threatened by regular occurrence extremely high-temperature (EHT) events. Currently, an innovative technology known as supplementary irrigation with ceramic emitter (SICE) was developed to maintain soil moisture and promote tree growth under EHT. Nevertheless, it still unclear how SICE affects In this study, field experiment conducted monitor status Platycladus orientalis (P.orientalis) analyze physicochemical properties rhizosphere EHT SICE. The α diversity bacterial communities analyzed using high-throughput sequencing 16 S rRNA 18 genes. results indicated that consistently maintained water content (SWC) range from 0.26 cm3 cm−3 0.54 during entire experimental period conditions. Furthermore, marginally increased relative abundance Actinobacteriota, Acidobacteriota, Chloroflexi Methylomirabilota 1.61 %, 0.99 2.33 % 4.31 compared CK, respectively. comparison, significantly decreased Proteobacteria 11.93 including α-Proteobacteria γ-Proteobacteria, Additionally, improved absorption SOC nitrogen nutrients P.orientalis, which were 41.20 41.17 28.35 higher than respectively had significant positive effect on conversion SOM accelerated for P.orientalis EHT, resulting increasing stem diameter, height, crown breadth branch length 104.80 81.67 47.59 94.68 %.
