大白菜软腐病为我区大白菜生长中后期及贮藏阶段的最严重的病害,轻则减产,影响食用价值,重则全田全窖腐烂损失。过去采用了拔出田间病株,勤翻清除窖期腐烂病部的方法,虽有一定效果,但往往由于多次拔除,株数减少,总产降低,而多次翻窖清除损失亦大。1960年我们对生长期田间病株进行了复壮防治试验观察,初步取得一定成效,现整理如下,以供生产上参考: 一、试验方法 (一)第一次试验:在8月15日—8月22日白菜软腐病发病初期,先将病叶去掉后,采用了如下方法处理病部伤口和根部四周地表:1.布袋撒施石灰粉;2.手撒新鲜干燥的草木灰;3.背负式喷雾器喷洒1%波尔多液;4.喷洒1:40倍的食盐水;5.对照不处理。
Chinese cabbage soft rot disease is the most serious disease in the middle and late stages of Chinese cabbage growth and storage stage, ranging from reduced production, affecting the edible value, while the whole field full pit decay loss. In the past, the methods of pulling out the diseased plants in the field and removing the decayed rot parts of the pit were frequently used. Although there are certain effects, the number of strains is often reduced due to repeated removal and the total output is reduced. In 1960, we conducted a rejuvenation prevention and control trial of the diseased plants in the field during the growth period, and achieved some initial results. Now we have sorted out the following information for production reference: I. Test Methods (I) The first test: On August 15 -8 On the 22nd of cabbage soft rot disease early onset, the first diseased leaves removed, the following methods are used to deal with diseased wounds and roots around the surface: 1, bag sacking of lime powder; 2 hand-sprinkled fresh dry ash; 3 piggyback Sprayer 1% Bordeaux spray; 4. Spray 1:40 times the salt water; 5. The control does not handle.
