摘要
2016-17 rabi季期间,在白沙瓦农业大学的新开发农场进行了现场试验。以小麦品种阿塔·哈比卜为研究对象,采用播种和混合罐施除草剂的方法,考察其田间性能。试验采用随机完全区组(RCB)设计,设4个重复,以减少试验结果的误差。为适应试验的实际需要,以不同的播种方式为主要小区,以罐式混合除草剂为次要小区,对不同处理间可能存在的正差异进行了突出处理。子地块大小为1.5 X 3 m,行间距保持30 cm。记录了杂草密度m-2、鲜、干杂草生物量(kg)、株高(cm)、穗长(cm)、叶面积(cm)、分蘖数(m-2)、穗数-1、千粒重(g)、生物产量(kg ha-1)、籽粒产量(kg ha-1)、收获指数(%)等数据。为了避免数据的重复或错误,对这些数据参数进行了非常仔细的正式观察。野外观察记录到的有害杂草有:黄花苜蓿、凤尾花、大戟、小蝴蝶花、黄花苜蓿、长牙紫花苜蓿、卷花紫花苜蓿、冠状花紫花苜蓿、多形草紫花苜蓿、鸡冠花紫花苜蓿、鸡冠花紫花苜蓿、鸡冠花紫花苜蓿和狐尾草。结果表明,不同播种方式对水稻株高、穗数、千粒重和生物产量的影响均有统计学意义,表明所记录的数据参数具有明显的有效性。此外,除穗粒数1外,除草剂施用量对各参数的影响均具有统计学显著性,而播种方式与除草剂施用量的交互作用也不显著。在播种方式上,行播效果较好。一般认为,对阔叶杂草和禾草杂草施用60-72%的罐式混合除草剂,对各种杂草的治理效果显著。因此,与未经处理的处理相比,即时结果提供了54%的产量增加。综上所述,在白沙瓦-巴基斯坦的农业气候条件下,行播配罐混播除草剂更适合麦田杂草治理和增产。
A field experiment was conducted at the new developmental farm, the University of Agriculture Peshawar during rabi season 2016-17. A wheat variety Ata Habib was selected to be investigated to check its performance by adopting methods of sowing and mixed tank herbicides application. The experiment was arranged in split plot with randomized complete block (RCB) design and 4 replications to reduce the error of the results. For practical adaptation of the experiment, the sowing methods were presented as the main plots, while tank mixed herbicides were kept in the sub-plots to get good prominent results for possible positive differences among the treatments. The sub-plot size measured as 1.5 X 3 m while row to row distance was kept 30 cm. Data were recorded on weed density m-2, fresh and dry weed biomass (kg) , plant height (cm), spike length (cm), leaf area (cm) , number of tillers (m-2) , Number of grains spike-1, 1000 grain weight (g), biological yield (kg ha-1), and grain yield (kg ha-1), Harvest index (%). These data parameters were formally observed with great care to avoid any repetition or error of the data. Few noxious weeds were observed and recorded in the field viz. Avena fatua, Anagallis arvensis, Euphorbia helioscopia, Phalaris minor, Poa annua, Medicago denticulata, Convolvulus arvensis, Coronopus didymus, Fumaria polymorpha, Melilotus parviflora, Chenopodium album and Rumex crispus. The obtained results indicated that sowing methods were statistically significant for plant height, grains spike-1, 1000-grain weight and biological yield that showed a clear effectiveness of the recorded data parameters. In addition to this, herbicides applications were also were also statistically significant for all the parameters except grains spike-1, while the interaction of sowing methods and herbicides application were also non-significant. In sowing methods, line sowing provided satisfactory results. As general understandings various weeds were managed significantly through tank mixed herbicide applications with a ratio of 60-72% for broad leaf and grassy weeds respectively. Consequently the instant results provided 54% increased yield compared to the untreated treatments. Hence it is concluded that , line sowing in combination with tank mixed herbicides are more suitable for management of weeds in the wheat field and increased yield in the agro climatic conditions of Peshawar-Pakistan.
