茶根腐病类是热带、亚热带产茶国森林垦复茶园和山地茶区的主要病害之一,病菌侵染茶株后,可导致茶树生长衰弱,或全株死亡,并逐株蔓延,造成成片茶树死亡,对茶叶生产危害很大。应用省茶叶研究所研制成功的广谱杀菌剂—50％TY杀菌剂进行防治,效果显著。现将试验整理报道如下。材料和方法 (一)试验地选用茶根腐病类发生严重并有明显病源中心的投产茶园,1958年直播、安化群体品种,种植密度4.5×(?)8尺,
Tea root rot is one of the major diseases in tea plantation and mountain tea plantations in tropical and subtropical tea-producing countries. Infection of tea plants can result in the weak growth of tea plants or the death of whole plants and strain by strains. A piece of tea died, a great harm to tea production. Application Province Tea Institute developed a broad-spectrum fungicide -50% TY fungicide for prevention and treatment, the effect is significant. The test is now reported as follows. Materials and Methods (I) Tea plantations were selected for trial on the occurrence of tea root rot with obvious disease centers. In 1958, the planting varieties of Anhua, planting density 4.5 × (?) 8 feet,
