| 摘 要： | 本文分析了辽宁省2021年春播期气象条件及其对农业的可能影响,结果表明:1)辽宁省2021年春播期回暖不稳定,5月气温整体偏低,全省平均降水量接近常年,时空分布不均;全省土壤墒情总体好于历年。2)辽宁省水稻育秧移栽基本正常,旱田作物播种持续时间偏长,5月底全省春播基本结束,春播总体开展顺利。3)建议树立作物全生育期"抢积温、促早熟"观念,提前做好玉米防倒伏工作,做好防汛抗涝准备工作。

| Abstract: | This study analyzed the meteorological conditions in the spring sowing period of 2021 in Liaoning Province and their possible impact on agriculture. The results are as follows. First, temperature rose unsteadily during the spring sowing period of 2021 in Liaoning Province, and the temperature in May overall remained relatively low, and average precipitation in the province was close to the normal level, and precipitation was unevenly distributed in time and space;the soil moisture content in the whole province was overall higher in 2021 than in previous years. Second, the transplanting of rice seedlings in Liaoning Province was overall conducted normally, and the sowing time of dry-field crops lasted relatively long. The spring planting was overall carried out smoothly in the whole province and basically finished by the end of May. Thirdly, it is recommended to utilize temperature accumulation timely and promote early maturity during the whole growth period of crops, take measures in advance to prevent lodging of corn, and make preparations for flood prevention and waterlogging prevention. |
