Analysis of the Impact of Abnormal Weather Conditions on Grain Crop Production in Pingluo County in 2021
摘要
Abstract
Abnormal weather conditions have a significant impact on crop growth and development.This study compared and analyzed meteorological data of abnormal weather conditions during the growth period of grain crops in Pingluo County in 2021,providing a reference for agricultural meteorological services in the county.By using temperature,precipitation,and sunshine data from February to September 2021 and comparing them with historical values(1991 to 2020),this paper elaborated on the adverse effects of weather conditions such as abnormally high temperature during the spring sowing period,the first soaking rain in March,sustained extreme high temperatures in July,and abnormally low summer precipitation on wheat,corn,rice and soybean production.The results showed that the high temperature during the wheat sowing period in 2021 significantly reduced the wheat sowing area compared to the plan.The continuous high temperature and meteorological drought during the flowering period of maize promoted the widespread occurrence of diseases and pests,resulting in reduced yields.The first soaking rain affected rice sowing,with windy weather after sowing causing seedling drift.The high temperature during the flowering period of early maturing varieties caused poor fertilization,increased empty blight rate,and affected yield.High temperature at soybean flowering stage affected pollination,drought and low rainfall affected pod setting,and low temperature affected filling at grain filling stage,resulting in yields significantly lower than that in 2020.关键词
