摘要： 利用濉溪县1958—2004年小麦产量资料和相应的降水资料，进行同步统计分析，结果表明：小麦气象产量与播种~分蘖和返青~拔节期的降水量显著正相关，与抽穗~成熟期的降水量显著负相关。适宜的降水量为：底墒水60~120mm，生育期内降水220~290mm。濉溪县小麦生产过程中降水总量适中，部分时段略显不足，旱多于涝，要优化品种结构，抢墒早播，浇好播种底墒水、分蘖越冬水和拔节孕穗水，集雨保墒。

Abstract: Utilize the materials of output of the wheat and corresponding precipitation materials of 1958-2004 year of Suixi county, Carry on synchronous statistical analysis, The result shows : Wheat meteorological output sow wheat divide into tiller and turn green remarkable positive correlation of precipitation , wheat of jointing stage, Shoulder with the precipitation of mature period notably relevantly with earing. The suitable precipitation is: Soil moisture water60~120mm, Precipitation in breeding time220~290mm. Precipitation is moderate in total amount in the wheat production process of Suixi county, Slightly show insufficiently in some period, The drought exceeds the waterlogging, Optimize the structure of variety, While the moisture in the soil is sown early, Easy to water to sow the soil moisture water, Divide tiller survive the winter ink and Jointing booting water, Collect the rain and preserve soil moisture.
