用2％“科瀚98”抗旱保水剂拌种法处理对弯孢菌叶斑病有不同抗病性的供试玉米品种,于出苗期、5～6叶、7～8叶及成熟后期调查玉米长势,并在自然发病情况下,分析经济产量。实验表明,保水剂在一定程度上促进了玉米的生长发育并提高了自然发病田的经济产量。5～6叶期人工接种弯孢菌叶斑病实验表明,保水剂在常规抗旱抗减产的同时,在一定程度上提高了玉米的抗病能力。本文明确了保水剂处理可以作为一种有效的抗玉米弯孢菌叶斑病的栽培措施。
Corn varieties with different resistance to Curvularia leaf spot were treated with 2% “科瀚 98” drought-resistant water-retaining agent seed dressing. At the emergence stage, 5 ~ 6 leaves, 7 ~ 8 leaves and mature stage Growing maize, and in the case of natural disease, analyze economic output. Experiments show that water retention agent to some extent, promote the growth and development of maize and increase the economic yield of natural fields. Artificial inoculation with Curvularia leaf spot in 5 ~ 6 leaf stage experiments showed that the water-holding agent improved the disease-resistant ability of maize to a certain extent at the same time of conventional drought-resistance and yield-reducing. This article made clear that the water-retaining agent can be used as an effective cultivation method against Curvularia lunata leaf spot.
