摘要

在田间条件下，研究向日葵水提物与亲和除草剂联合施用对小麦品种TD-1杂草管理和生产的化感作用。试验分3个重复进行，平均地块面积保持在3 × 5m (15 m2)。结果表明，与对照处理相比，施用向日葵水提物(1:10)@ 20 L ha-1 (25 DAS 1次)+亲和度50 WP @ 0.75 kg ha-1 (25 DAS 1次)处理的杂草密度、鲜重、干重和杂草防治效果分别显著降低(P<0.05) 90.33%、89.31%、89.61%和90.33%。施用向日葵水提取物(1:10)@ 20 L ha-1 (25 DAS 1次喷施)+亲和性50 WP @ 0.75 kg ha-1 (25 DAS 1次喷施)，与对照相比，分蘖数(32.34%)、株高(14.59%)、穗长(27.89%)、穗1粒(16.80%)、粒重(47%)、种子指数(19.60%)和籽粒产量(51%)显著增加。综上所述，向日葵水提液与除草剂配合使用可成功防治小麦窄叶病和宽叶病。

Allelopathic effects of sunflower water extract integrated with affinity herbicide on weed control and wheat yield

The aim of present study was to investigate the allelopathic impact of sunflower water extract integrated with affinity herbicide on weed management and production of wheat variety TD-1 under field condition. The trial was carried out in a three replicated and the average plot size was kept at 3x5m (15 m2). The obtained data showed that the all the treatments considerably (P<0.05) minimized weed density, weed fresh weight, weed dry weight and weed control up to 90.33, 89.31, 89.61, 90.33% with application of sunflower water extract (1:10) @ 20 L ha-1 (One spray at 25 DAS) + Affinity 50 WP @ 0.75 kg ha-1 (One spray at 25 DAS) than control treatment. The application of sunflower water extract (1:10) @ 20 L ha-1 (One spray at 25 DAS) + Affinity 50 WP @ 0.75 kg ha-1 (One spray at 25 DAS) significantly increased number of tillers (32.34%), plant height (14.59%), spike length (27.89%), grains spike-1 (16.80%), grain weight plant-1 (47%), seed index (19.60%) and grain yield (51%) of wheat as compared with control. Overall results indicated that the sunflower water extract integrated with herbicide can be successfully used to control the narrow and broad leaves in wheat crop.

期刊介绍： The fundamental task set by the editors of the journal is to bring together and present a diversity of research connected with ecology. Apart from the traditional ecological research areas, the scope of the journal will embrace more peripheral ecological issues connected with other disciplines of biology. Recognizing the increasing importance of the humanities in ecological research, the editors will strive to give such issues due representation in the journal. We hope to encourage the researchers contributing to the journal to adopt an unconventional approach to solving ecological problems, to go beyond classical, well-established conceptions, and to include methodological and anthropological issues. Such an approach is validated by the intensive development of the sciences bordering on both biology and the humanities that has been observed over recent years.
