大白菜“于烧心”为普遍发生的严重病害之一。我市发病面积2000亩左右,占大白菜种植面积的22.3％,病株率一般为15～25％,重病地块达50～60％,严重降低了大白菜的品质和产量。为了摸索出有效的防治办法,1983年,我们在南开大学生物系教师的帮助指导下,在白菜生长期用撒施含钙颗粒剂补充钙的方法,对“干烧心”病进行防治试验,收到了较好的防治效果。一、试验地基本情况试验地安排在郊区发病最重的平原乡臧营二队。品种为青麻叶核桃纹。试验设处理与对照,三次重复,每小区0.093亩,共0.62亩(包括保护行)。8月10日播种,14日齐
Chinese cabbage “in heartburn” is one of the most common diseases. The disease area of about 2000 acres in our city, accounting for 22.3% of the planting area of Chinese cabbage, the diseased plant rate is generally 15 to 25%, 50 to 60% of severely ill land, seriously reducing the quality and yield of Chinese cabbage. In order to find out an effective control measures, in 1983, with the help of the faculty of biology of Nankai University, we conducted the prevention and cure test of “heartburn” disease with the method of calcium supplementation with calcium granules in cabbage growth stage To a better control effect. First, the basic situation of the experimental site Experimental arrangements in the suburbs of the most serious plains Township Zangying second team. Variety of blueberry leaves walnut pattern. Test set up treatment and control, three replications, each plot of 0.093 mu, a total of 0.62 mu (including the protection line). August 10 sowing, 14, Qi
