摘要

植物的空间分布影响着萝卜的产量,因此要优化萝卜的种植,必须确定理想的株距。本试验旨在评价不同栽培间距下萝卜品种的农艺性能。该实验于2017年6月至7月在巴西马塞诸塞州Codó马兰赫联邦教育、科学和技术研究所实验场进行。试验采用随机区组设计,5个重复,采用2×2因子排列。试验包括2个品种(花花、蓬花和萨克森)和2个株距(5 ~ 8cm),共20块试验田。每个试验田采集6株数据。对萝卜植株的农艺参数:总鲜重(TFW)、根鲜重(RFW)、根平均直径(RMD)、根平均长度(RML)和根产量(RY)进行评价。各因子(品种和株距)对TFW、RFW、RML和RMD均无显著影响。植株间距对萝卜作物产量有显著影响,采用5cm间距时产量较高。

Agronomic performance of Raphanus sativus L. cultivars grown under different spacings
An ideal spacing between plants should be established for the optimization of radish (Raphanus sativus L.) crops since the plant spatial distribution of plants affects the crop yield.  This study was conducted aiming to evaluate the agronomic performance of radish cultivars grown under different spacings. The experiment was conducted at the Experimental Field of the Federal Institute of Education, Science, and Technology of Maranhão, in Codó, MA, Brazil, from June to July 2017. The experiment was conducted in a randomized block design with five replications, using a 2×2 factorial arrangement. The factors consisted of 2 cultivars (Sparkler Ponta Branca and Saxa) and 2 spacings between plants (5 and 8cm), totaling 20 experimental plots. Data were collected in  6  plants from each experimental plot. The agronomic parameters: total fresh weight (TFW), root fresh weight (RFW), root mean diameter (RMD), root means length (RML), and root yield (RY) of the radish plants were evaluated. The factors (cultivars and spacing between plants) had no significant effect on TFW, RFW, RML, and RMD. The spacing between plants has a significant effect on the yield of radish crops of the cultivar Saxa, and higher yields are found when using the spacing of 5cm.
