一、霜害情况宿县地区是我省主要小麦产区之一,4月上、中旬經常出現春霜冻害。这时小麦已普遍拔节、孕穗,失去了抗寒能力,因此,常因春霜冻害造成减产損失。今年4月9日清晨,又遭受了自1953年以来最严重的一次春霜冻害,冻害的程度仅次于1953年4月12日的一次。1953年冻害后,小麦减产6成左右,今年这次霜冻,虽然在5月份天气凉爽,无西南干旱风为害,有利于霜冻后小麦的灌浆成熟的情况下,估計受害地区仍要减产3—5成。据宿县农业气象試驗站气象资料的記載,自1953年以来9年中,春霜出现在4月上、中旬的有5次(1953、1954、1957、1960、1961年),其中1960年4月2日的一次最早,1954年4月20日的一次最迟;低溫的强度以1954年4月20日一次最低气溫摄氏2.9度为最高,1953
First, the frost damage situation Su County is one of the major wheat producing areas in our province, April, mid-spring frost damage often occurs. At this time, wheat has been generally jointed, booting, losing its ability to deal with cold. Therefore, it is often caused by loss of spring frost damage. On the early morning of April 9 this year, it suffered the worst frost damage ever since 1953, only second to April 12, 1953. After the frost damage in 1953, about 60% of wheat was cut. Although this year’s frost was cool in May and no southwestern arid wind was detrimental to the ripening of winter wheat after frost, it is estimated that the affected area will still have to cut its output by 3-5% to make. According to the meteorological data of the Suqian Agricultural Meteorological Experiment Station, the spring frost occurred in April over the nine years since 1953 with five (1953, 1954, 1957, 1960 and 1961) in the middle of the year, of which 4 in 1960 One of the earliest on the 2nd of the month, a latest on April 20, 1954; the intensity of the low temperature was the highest at a minimum temperature of 2.9 degrees Celsius on April 20, 1954 and 1953
