摘要
本研究旨在探究小麦苗期黄花叶病的发生规律,并评估春季药剂防治的效果。从2018年起,在枣庄市进行了田间调查,以系统分析小麦黄花叶病发生情况。2022-2023年,选取3个地块开展苗期药剂防治试验。防治措施包括在小麦起身期每公顷喷施2次20%盐酸吗啉胍可湿性粉剂2250 g+30%毒氟磷可湿性粉剂750 g+0.01%芸苔素内酯可溶液剂225 mL+6%寡糖·链蛋白可湿性粉剂1200 g+98%磷酸二氢钾2250 g+含氨基酸水溶肥料750 g,面积分别为1333.4、666.7、666.7 m^(2),对照均喷施清水,面积分别为1333.4、666.7、666.7 m^(2)。研究结果表明,喷施上述药剂可以减轻小麦黄花叶病病情严重度,2次喷药后平均防效分别为29.6%、42.46%。与对照相比,喷药处理的小麦株高平均增加5.27 cm,单株鲜重平均增加0.44 g,单株次生根条数平均增加3.17条。3个试验地块的产量分别达到了5657.85、6777.12、7868.37 kg/hm2,而对照地块的产量分别为4776.52、5435.58、7223.63 kg/hm^(2)。因此,喷药处理的产量较对照分别提高了881.32、1341.54、644.75 kg/hm^(2),平均增产955.87 kg,平均增产幅度为17.35%。综上所述,小麦苗期通过喷施特定混合药剂,可以有效减低黄花叶病的危害,实现减损和增产的目的。本研究结果为小麦黄花叶病的防治提供了重要的理论依据和技术支持。
In order to effectively control wheat yellow mosaic disease at seedling stage and reduce the effect on wheat yield,the occurrence of wheat yellow mosaic disease was investigated in the field from 2018,and the regularity of occurrence of wheat yellow mosaic disease was analyzed systematically.From 2022 to 2023 year,three plots were selected to conduct pesticide control experiments at seedling stage,two sprays of 20% moroxydine hydrochloride WP 2250 g+30% difluorophos WP 750 g+0.01%brassinolide soluble solution 225 mL+6%oligosaccharide·Chain protein WP 1200 g+98%Monopotassium phosphate 2250 g+750 g water soluble fertilizer containing amino acids were applied to wheat at rising stage,the area was 1333.4,666.7,666.7 m^(2) respectively,and the control was sprayed with water,the area was 1333.4,666.7,666.7 m2respectively.The results showed that spraying fungicide could reduce the severity of wheat yellow mosaic disease,and the average control effect was 29.6%and 42.46%,respectively,and the average plant height and fresh weight increased by 3.24 cm and 0.44 g,respectively,the average number of secondary roots per plant increased by 3.17.The yields of the three plots were 5657.85,6777.12,7868.37 kg/hm^(2),respectively,and those of the control were 4776.52,5435.58,7223.63 kg/hm^(2),respectively.The yields of the three plots were increased by 881.32,1341.54,and 644.75 kg/hm^(2),respectively,the average yield increase was 955.87 kg and 17.35%.Spraying fungicide at the seedling stage of wheat can reduce the damage degree of the disease and achieve the effect of preventing disease,reducing damage and increasing yield of wheat.
