Water consumption, soil nitrate-nitrogen residue and fruit yield of drip-irrigated greenhouse tomato under various irrigation levels and fertilization practices

The excessive irrigation and chemical fertilizer application in the greenhouse can lead to resources waste, environmental pollution instable or even reduced fruit yields. A four-season experiment was conducted with three levels (W1, 100%ETc; W2, 75%ETc; W3, 50%ETc, where ETc crop evapotranspiration) five fertilization practices (CC, chicken manure fertilizer; SO, only soluble organic SC, SOSC, CK, a control no fertilizer) explore their integrated effects on growth, water consumption, soil nitrate-nitrogen residue yield of drip-fertigated tomato. results showed that root shoot ratio autumn (3.21 ×10−2) greater than spring (2.05 ×10−2). Fruit dry matter had most significantly positive relationship both seasons; however, leaf matter, stem SPAD autumn. average over four growing seasons 70.68, 67.16 62.66 t ha−1 under W1, W2 respectively. SOSC increased plant height, tomato (0–60 cm), while SO obtained ratio. Both SC consumption at seedling stage, blooming setting stage CC; harvest SC.

GlobalAMFungi: a global database of arbuscular mycorrhizal fungal occurrences from high‐throughput sequencing metabarcoding studies

New Phytologist, Год журнала: 2023, Номер 240(5), С. 2151 - 2163

Опубликована: Окт. 2, 2023

Arbuscular mycorrhizal (AM) fungi are crucial mutualistic symbionts of the majority plant species, with essential roles in nutrient uptake and stress mitigation. The importance AM ecosystems contrasts our limited understanding patterns fungal biogeography environmental factors that drive those patterns. This article presents a release newly developed global dataset (GlobalAMFungi database, https://globalamfungi.com) aims to reduce this knowledge gap. It contains almost 50 million observations Glomeromycotinian amplicon DNA sequences across 8500 samples geographical locations additional metadata obtained from 100 original studies. GlobalAMFungi database is built on sequencing data originating taxon barcoding regions in: i) small subunit rRNA (SSU) gene; ii) internal transcribed spacer 2 (ITS2) region; iii) large (LSU) gene. an open source access initiative compiles most comprehensive atlas distribution. designed as permanent effort will be continuously updated by its creators through collaboration scientific community. study also documented applicability better understand ecology taxa.

Grassland degradation amplifies the negative effect of nitrogen enrichment on soil microbial community stability

Global Change Biology, Год журнала: 2024, Номер 30(3)

Abstract Although nitrogen (N) enrichment is known to threaten the temporal stability of aboveground net primary productivity, it remains unclear how alters that belowground microbial abundance and whether its impact can be regulated by grassland degradation. Using data from N experiments at temperate grasslands with no, moderate, severe, extreme degradation degrees, we quantified soil (hereafter ‘microbial community stability’) using ratio mean quantitative PCR standard deviation over 4 years. Both bacterial fungal sharply decreased when input exceeded 30 g m −2 year −1 in non‐degraded grasslands, whereas a reduction this threshold occurred degraded grasslands. Microbial species diversity, asynchrony, associations jointly altered stability. Interestingly, linkages between plant were strengthened suggesting plants microbes might depend on each other keep stable communities harsh environments. Our findings highlighted importance regulating responses provided experimental evidence for understanding relationships

Introduction of Panax notoginseng into pine forests significantly enhances the diversity, stochastic processes, and network complexity of nitrogen-fixing bacteria in the soil

Introduction Nitrogen-fixing bacteria (NFB) have a pivotal impact on the nitrogen cycle within agroforestry systems. The organic management of Panax notoginseng (sanqi)- Pinus armandii (SPA) system resulted in deficiency because lack application chemical fertilizers. Therefore, assessing variability NFB due to cultivation sanqi SPA becomes crucial. Methods seasonal dynamics abundance, diversity, and community structure soil monocropping pine (MP) systems were assessed using real-time quantitative polymerase chain reaction high-throughput sequencing technology. Results discussion Sanqi triggered decrease abundance but increased α diversity. Additionally, significant differences noted between MP Moreover, Bradyrhizobium Azospirillum after was cultivated.
