近年来,气候变异,作物生长季节出现了气温偏低趋势。为了搞清低温对秋作物的影响程度,我们根据历年的作物产量与气象资料,对两者的关系作了探讨分析,简述如下: 一、低温与玉米、各子产量的关系。 1.玉米是一种喜温、高产作物。从播种出苗到成熟的全生育过程,都需较高的温度条件。据资料,玉米在全生育过程中对温度的基本要求是,日平均气温稳定通过10℃的活动积温达
In recent years, climate variability, crop growing season appeared the trend of low temperature. In order to understand the impact of low temperature on autumn crops, we conducted a discussion and analysis on the relationship between the two crops based on crop production and meteorological data over the years, summarized as follows: First, the relationship between low temperature and corn, each yield. Corn is a warm, high-yield crop. From sowing seedlings to mature full-breeding process, require higher temperature conditions. According to statistics, the basic requirement of corn in the whole growth process is that the daily average temperature is stable and reaches 10 ° C
