1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundHigh-density spindle and V-trellis pear orchards face critical bottlenecks including complex canopies, poor sprayer adaptability, insufficient droplet penetration, uneven deposition, and low pesticide utilization. To overcome these issues, this study established a systematic framework including structure adaptation, parameter optimization, mechanism analysis, performance validation, and multi-objective evaluation. A dedicated air-assisted sprayer was developed using modular design, computational fluid dynamics (CFD) simulation, intelligent target detection, and high-speed flow-field visualization. The spray characteristics, air-droplet coupling, and operational parameters were optimized and verified in laboratory and field tests.

resultsThe plant-derived adjuvant decreased surface tension to 54.23 mN m

conclusionThis study resolves the poor adaptability of conventional sprayers, reveals the air-droplet coupling transport mechanism, and provides a technical scheme for precision green plant protection in dense pear orchards, supporting the customized upgrading of agricultural spraying equipment. © 2026 Society of Chemical Industry.
