赤霉病是我省三麦的主要病害。镇江地区农科所和丹阳、溧阳、金坛等县农试站吸取群众传统的消毒灭菌经验,用明矾、肥皂粉等进行试验,收到了较好的防治效果。 在三麦盛花期用1.5斤、3斤明矾溶于200斤水中,一次喷雾,防效分别达到74.5％和78.1％,有一定增产效果,对麦子发芽也无影响。 为了观察明矾对赤霉病的防治作用,他们用0.5—1％浓度的葡萄糖液及0.1、0.2、0.5、1％浓度的明矾、葡萄糖(浓度同上)混合液进行赤霉病菌孢子室内培养试验。经过四天观察,
Fusarium head blight is the main disease in our province three wheat. Agricultural Science Institute of Zhenjiang and Danyang, Liyang, Jintan and other county agricultural experiment station draw lessons from the traditional disinfection and sterilization experience, with alum, soap and other tests, received good control effect. In the three wheat full flowering with 1.5 pounds, 3 kg of alum dissolved in 200 pounds of water, a spray, control effect reached 74.5% and 78.1%, respectively, a certain yield increase effect on wheat germination also had no effect. In order to observe the effect of alum on the control of Fusarium head blight, they tested the spore culture of Fusarium graminearum with 0.5-1% glucose solution and 0.1, 0.2, 0.5 and 1% concentrations of alum and glucose (above). After four days of observation,
