天津1976年7月28日唐山、丰南强烈地震波及我场,使果树生产遭受重灾,已投产果树受害率高达53.3％,至77年5月统计,死亡或濒临死亡的投产果树占46.3％。地震对果树栽培的影响尚属新课题,既往缺乏报道,故将我队震后考察情况报告于后。一、受害情况 1.果树树体遭受的损害 (1) 震后情况: ①僵叶死亡:震后1—2日内,叶片不及形成离层脱落,枝干皮部褐变,输导组织解体,树体死亡,致使僵枯叶片悬于树上经久不落。此为最严重的一种。②落叶:震后叶片迅速脱落,3—4天 Tianjin On July 28, 1976, a strong earthquake in Tangshan and Fengnan affected my farmland and caused heavy losses in the production of fruit trees. As a result, 53.3% of the fruit trees have been put into operation. By May of this year, statistics showed that 46.3% of the fruit trees were dying or dying, . The impact of the earthquake on the cultivation of fruit trees is still a new topic, lack of coverage in the past, so I report the situation after the earthquake report. First, the victim situation 1. Fruit tree damage (1) after the earthquake situation: ① dead leaves die: 1 to 2 days after the earthquake, the leaves do not form off the layers, the branches of the skin brown, the disintegration of the guiding tissue, Tree dead, resulting in dead leaves hanging in the tree over time. This is the worst kind. ② leaves: leaves quickly after the earthquake off, 3-4 days
