Using perennial groundcover crops to suppress weeds and thrips in the southeast cotton belt

This is digital research data corresponding to a published manuscript, Using perennial groundcover crops to suppress weeds and thrips in the southeast cotton belt, in Crop Science, Vol. 63 p. 3037 - 3050.
Modern cotton production (Gossypium hirsutum L.) in the United States relies on chemical and physical inputs that increase the environmental and monetary costs of managing the crop. Perennial groundcover crops (PGCC) may reduce inputs by persisting in the interrow spaces of the cotton crop during summer months. A 2-year field study was conducted in Florence, SC, to evaluate growing PGCCs with cotton using a 4 × 4 Latin square consisting of four cover crop treatments: (1) a fallow, unplanted control, (2) annual ryegrass (Lolium multiflorum Lam.) monoculture, (3) a binary red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) mixture, and (4) a trinary mixture of annual ryegrass, red clover, and white clover. Fallow and annual ryegrass treatments were killed with a bur...

本数据集对应一篇已发表的学术论文，题为《美国东南部棉区利用多年生地表覆盖作物抑制杂草与蓟马》，刊载于《作物科学》（Crop Science）第63卷，第3037-3050页。
美国当前的陆地棉（Gossypium hirsutum L.）生产依赖化学与物理投入品，这会提升棉花种植的环境成本与经济成本。多年生地表覆盖作物（PGCC）可通过在夏季留存于棉田行间空间，降低生产投入。本研究于南卡罗来纳州佛罗伦斯市开展了为期2年的田间试验，采用4×4拉丁方设计，评估棉田套种PGCC的效果，共设置4种覆盖作物处理：（1）休闲未种植对照组；（2）一年生黑麦草（Lolium multiflorum Lam.）单作；（3）红三叶（Trifolium pratense L.）与白三叶（Trifolium repens L.）二元混播组合；（4）一年生黑麦草、红三叶与白三叶三元混播组合。休闲与一年生黑麦草处理采用...
