商丘市气候变化对小麦生长发育及产量的影响
Influence of Climate Change on the Growth and Yield of Wheat in Shangqiu City
摘要
Abstract
Using the meteorological data in Shangqiu City from 1964 to 2010 and the district trial records of Shangqiu Academy of Agriculture and Forestry during 1985-2010,the suitable sowing period,the winter beginning in meteorology,the winter beginning of production,returning green stage,jointing stage,heading stage and mature stage were determined.Based on the statistics of wheat yield from 1985 to 2010,the correlation between wheat climatic yield and sunshine,temperature,rainfall and wheat yield was analyzed by multivariate regression analysis.The research showed that with the increase of temperature and decrease of sunshine hours,the sowing period,wintering period and mature stage of wheat in this area were delayed,and the returning green stage,jointing stage and heading stage of wheat showed a premature trend,resulting in the shortening of the whole growth period and wintering period of wheat,the filling stage was prolonged,and the yield was gradually aggravated by the climate.The actual yield of wheat was extremely significantly and positively correlated with the accumulated temperature during the growth period and negatively correlated with the sunshine hours and precipitation,among them,the correlation with sunshine hours was significant.Under high temperature and drought stress,the grain filling rate was inhibited,the maximum filling rate appeared ahead of time,and the duration of grain filling shortened,which led to the decrease of grain dry matter accumulation and grain weight.The accumulated temperature was the dominant factor affecting wheat yield.关键词
