Analysis of Relationship between Precipitation and Growth and Development of Summer Soybean in Suixi County

Abstract

Abstract: Based on the observed meteorological and soybean yield data from 1970 to 2004 in Suixi County,the statistical analysis of relationship between precipitation and yield of summer soybean was made.The result showed that the correlation between precipitation during seedling,filling stage and precipitation days during podding and the whole growth period and soybean yield were significantly positive.Soybean yields were mainly constrained by spatial and temporal abnormity characteristics of summer precipitation in soybean growing areas.The suitable precipitation range during the growing period of summer soybean was determined.

Key words: Summer soybean, Summer soybean, Precipitation, Yield
