为探索适合张家口地区葡萄喷施生物农药阿泰灵的合适时期,实现葡萄病害合理化防控,提高葡萄果实品质,2020-2022年采用分别在1年生'蜜光'葡萄和2016年定植'峰光'葡萄的不同生长时期喷施0.1％浓度阿泰灵,测定葡萄霜霉病发生情况、1年生'蜜光'葡萄生长情况、多年生'峰光'葡萄果实品质情况.结果表明,在1年生'蜜光'葡萄4～6叶期喷施2次0.1％阿泰灵,霜霉病发病率降低14.2个百分点,病情指数降低7.53,增加'蜜光'葡萄距地面20 cm处周长0.86 cm,增加'蜜光'葡萄成熟枝条长度65.17 cm;在多年生'峰光'葡萄花前喷施2次0.1％阿泰灵,霜霉病发病率降低15.73个百分点,病情指数降低9.64,果皮颜色为蓝黑色,增加'峰光'葡萄单粒重2.60 g,增加'峰光'葡萄可溶性固形物含量1.47个百分点,降低'峰光'葡萄可滴定酸含量0.12个百分点,增加'峰光'葡萄固酸比15.09.生物药剂可增强葡萄抗性,降低葡萄病害发生率,对葡萄生长和果实品质的改善有一定的作用.
Effect of Spraying Time of Atailing on Prevention and Control of Grape Diseases and Grape Quality
An experiment was conducted to explore a suitable period for spraying the biological pesticide Atailing on grapes in the area of Zhangjiakou,which would realize the prevention and control of grape diseases rationally and enhance the quality of grapes.In the experiment,0.1％concentration of Atailing was sprayed at different growth stages of 1-year old'Miguang'grape and 2016 planted'Fengguang'grape respectively from 2020 to 2022 in order to observe the occurrence of grape downy mildew,the growth condition of the 1-year old'Miguang'grape,and the fruit quality of'Fengguang'grape.The results showed that the incidence rate of downy mildew was reduced by 14.2 percentage points,the disease index was reduced by 7.53,the perimeter of the grape trunk 20 cm above the ground was increased by 0.86 cm,and the length of the mature branch of the grape was increased by 65.17 cm when 0.1％concentration Atailing was sprayed twice at the stages of 4-6 leaves on the 1-year old'Miguang'grape.While,the experiment results also showed that the incidence rate of downy mildew was reduced by 15.73 percentage points,the disease index was reduced by 9.64,the peel color of the grapes became blue black,the weight of a single'Fengguang'grape was increased by 2.60 g,and the soluble solids content of the grape was increased by 1.47 percentage points,and the titratable acid content of'Fengguang'grape was reduced by 0.12 percentage points,and the solid-acid ratio of'Fengguang'grape was increased by 15.09 when 0.1％concentration Atailing was sprayed twice before the flowering time of'Fengguang'grape.In conclusion,the biological agent of Atailing could enhance the grape resistance to diseases and reduce the incidence rate of grape diseases;also,it had certain effects on improving the growth condition and fruit quality of grapes.
