一九七六年初秋,晋南平原各种果树硕果累累,丰收在望.可是,翼城、曲沃、侯马、临汾、洪洞、蒲县、古县等都相继发现梨树、苹果、樱桃、土梨、杏树等果木树重新开花的情况.人们担心这是强烈地震的前兆.春花秋果,这是植物生长的普遍规律.个别树木则在夏、秋、冬三季开花,这是植物适应外界环境的结果.有时,当外界条件发生变化,其生长形式也可能发生相应的变化,或提前或推迟开花.那么,何以造成76年秋果树重花呢?经调查,主要有以下原因.一、有些果树在春季花期遇到旱、涝、病虫、低温等自然灾害,使花叶大量脱落,被迫进入休眠状态,到外界温度、水、肥等条件适宜时,促使已形成的花芽继续分化形成花粉和胚囊等,最后开出新花,甚至结出新果;
Early autumn of 1976, a variety of fruit trees in the Jinnan Plains fruitful, harvest in sight, however, Yicheng, Quwo, Houma, Linfen, Hongdong, Puxian, ancient county, etc. have been found pear, apple, cherry , Soil pear, apricot and other trees re-blooming.It is feared that this is a precursor to a strong earthquake.Quercus mulberry, which is a common law of plant growth.A few trees in the summer, autumn and winter flowering season, which is the plant Adapt to the external environment results.Of course, when the external conditions change, the growth pattern may also change accordingly, or in advance or postpone flowering.So, then, how to make 76 autumn heavy tree flowers? The survey, mainly for the following reasons.A, Some fruit trees encounter natural disasters such as drought, waterlogging, pests and diseases, low temperature and other disasters during the spring flowering season, causing the leaves to fall into dormancy state. When the external temperature, water and fertilizer are suitable, the formed flower buds will continue to differentiate The formation of pollen and embryo sac and so on, finally out of new flowers, and even bear fruit;
