通过清水浸泡麦穗使吸浆虫自然弹出,然后检查小麦吸浆虫。当天自然弹出吸浆虫占总虫数49.5%,7 d弹出占总数85%;水中淘穗法使吸浆虫与籽粒、颖壳自然分离,经浸水自然弹出,一遍淘穗,累计可检出98.2%吸浆虫;10块田对比检验,浸水淘穗法比传统剥穗法检查多获得虫量30.6%,t测验达显著水平;与实际虫量t测验差异不显著。在提高准确性、代表性同时,提高工效80%~90%。 Soak the wheat ears by soaking the water so that the Midge Pops naturally pops up and then checks the Midge. In the same day, 49.5% of the total number of inhaled Helicoverpa armigera and 85% of the total were popped up on the 7th day. In the water scouring method, somaclone was separated from the grain and glume shell naturally, 10 field comparison test, flooding scion method than traditional scopching method to obtain more than 30.6% of the number of insects, t test reached a significant level; and the actual worm t test was not significantly different. While improving the accuracy and representativeness, it will improve efficiency by 80% -90%.
