基腐病(俗名“白秧”)是早稻秧苗的一种生理障害。1963年4月中旬貴池县丘陵地区早稻秧苗于二至四片真叶、苗高二至三寸时,猛发此病。发病面积占秧田总面积65%左右。虽趁晴暖之机追施暖性肥提苗,但栽秧期仍迟四至六天,造成減产。作者赴里山、晏塘、大路等公社进行了調查。病征是,綠色叶片卷成針筒状,逐漸枯萎,变成白色,似已死亡。但检查,叶端虽退色,基部却仍带青色,拔心叶往往連根带起,証明尚有生机。以后追肥,仍能恢复生长,伹不及时挽救则成片死亡。据貴池县气象資料,在基腐病猛发前的半个月(4月1日至15日)时間,阴雨天有十一天,占73.3%,
Basal rot disease (commonly known as “white seedling”) is a physiological barrier to early rice seedlings. In mid-April 1963, early rice seedlings in the hilly Guichi County flocked to two or four true leaves, with a height of two to three inches. Incidence of the total area of about 65% of seedlings. Although taking advantage of sunny warm machine topdressing warm fertilizer Timmia, but the planting seedling is still four to six days later, resulting in reduced production. The author went to the mountain, Yan Tang, roads and other communes conducted a survey. Symptoms are, green leaves rolled into a cylinder, gradually withered, turned white, seems to have died. However, check, although the fade leaves, the base is still with a cyan, pull the leaf often with roots, proving that there are still vitality. After dressing, still able to restore growth, not timely rescue is a piece of death. According to Guichi County meteorological data, half a month before the rot on the basis of rot (April 1 to 15) time, rainy days have 11 days, accounting for 73.3%
