黑龙江省近三十年气候变化对大豆发育和产量的影响
Impacts of Climate Change on Development and Yield of Soybean over Past 30Years in Heilongjiang Province
摘要
Abstract
According to the 1980-2008 ground parallel observation data and daily meteorological data from 10 agro-meteorological stations in Heiiongjiang province, by using the mathematical statistics method, temporal and spatial characteristics of climate changes and its impacts on soybean development and yield were analyzed. The results showed that the climate in the study area trended to become warming-drying, accumulated temperature over 10℃ and average temperature in growth season increased, frost-free period extended,precipitation decreased from bloom to maturity of soybean;sunshine increased from podding to maturity. Light and heat resources increased significantly in the southern region. Soybean response to climate change varied with regions and developmental stages. Planting,emergence and the third leaves period had no significant change,except abnormally advanced in the west;blooming period advanced,hence,the interval from third leaves to blooming shortened,especially in north and middle area;podding,pod-filling and maturity period went ahead slightly,and warming was one of the main factors that advanced the growth of soybean. At a certain threshold, soybean yield increased with the rise of average temperature in the growth season. Consequently, there would be both advantages and disadvantages of climate warming-drying to the soybean production, hence, great importance should be attached for variety selection,introduction and planting pattern of soybean.关键词
