盩厔县黑河沿岸稻区,常年均有烂秧发生,各年輕重不一。1959年稻秧出苗后,又遭到低溫的侵襲,普遍发生了烂秧,一般秧田烂秧在20—30％左右,严重的达90％,不得不重新育秧。为了了解烂秧的原因,和群众防止烂秧的經验,我們于五月間在三高、富饒和大中三个生产大队,九个自然村进行了調查和訪問,茲将結果整理于后: 一、烂秧与气候变化的关系 59年5月上中旬的气候情况,根据三高队的观察記載,5月5日至11日均为阴雨天气,气温最低至7—8℃,而多风。同时在5月中旬內降溫三次,阴雨天气多刮西风,风力6至7级;晴天傍晚多南风,当时南山普遍降雪,因而夜間温度低,对秧苗十分不利。一般秧苗受
Xuyi County Heihe coastal rice area, perennial rotten seedlings have occurred, varying in weight and weight in different years. After the emergence of rice seedlings in 1959, but also by low-temperature invasion, the general occurrence of rotten seedlings, rotten seedlings in general about 20-30% rotten seedlings, severely up to 90%, had to re-seedling. In order to understand the causes of rotten seedlings and the masses’ experience in preventing rotten seedlings, we conducted surveys and interviews in three high-yielding, fertile and medium-sized production brigades and nine natural villages in May. The relationship between rotten seedlings and climate change In May 59, the climates of the upper middle reaches of May 59 were rainy and rainy from May 5 to May 11, with temperatures as low as 7-8 ℃ and windy. At the same time in mid-May cooling three times, rainy weather more scraping westerly, wind 6 to 7; sunny evening more southerly, when Nanshan generally snowfall, so the night temperature is low, the seedling is very negative. General seedlings by
