今年小麦取得了较好的收成,比1979~1980年增产2成以上。从小麦生育期间的农业气象条件来看,是利大于弊的。冬前积温接近常年,但11月气温明显偏高,麦苗锻练较好。春季升温快,温度高,生育期提前,灌浆期长,千粒重达到历史最高水平。不利气象条件是:持续干旱,底墒不足。冬初和冬末受两次较强冷空气影响,发生中度冻害。干旱地区死苗较重。灌浆期部分麦田受旱,影响千粒重。一、播种——越冬(9月下旬~3月上旬): 冬前及越冬期气象条件有利,苗齐苗壮。但受干旱及降温影响,发生较重冻害。1980年小麦播种期间,虽然干旱,底墒不足。但在小麦播种期间9月14日及10日9~12日分别有10毫米以上的降雨,对小麦播种出苗尚为有利。又加之管理抓的紧,据统计入冬前浇2水的麦田有200
This year wheat has achieved a better harvest, an increase of more than 20% over 1979-1980. From the agrometeorological conditions during the growth of wheat, it outweigh the disadvantages. Accumulated temperature before winter approaching perennial, but the temperature was significantly higher in November, wheat seedling exercise better. Rapid warming in spring, high temperature, early growth period, filling a long period, one thousand grain weight reached the highest level in history. Adverse weather conditions are: continued drought, inadequate moisture at the end. Affected by two strong cold air in winter and early winter, moderate frost damage occurred. Dead seedlings in arid areas heavier. During the filling stage, some wheat fields are affected by drought, affecting 1000-grain weight. First, sowing - overwintering (late September to early March): favorable weather conditions before winter and overwintering, Miaozhuang Miao Zhuang. However, due to the effects of drought and cooling, heavier frost damage occurred. During the wheat planting in 1980, although the drought, lack of end moisture. However, during the sowing of wheat on September 14 and September 10 to 9, respectively, there are more than 10 mm of rainfall, seedling emergence of wheat is still beneficial. Coupled with the management of the tight grasp, according to statistics before the winter irrigation 2 water 200 wheat fields
