本文采用赵光农场1971～1985年的日平均气温、降水和日照时数的实测资料、以旬为单位和黑河三号大豆小区产量的实测资料进行积分回归、逐步回归和相关分析,得到如下结论。在赵光地区生态条件下,对大豆生长发育的不利气候因素是:1)从时间剖面看,在5月下旬至6月中旬的日平均气温、降水、日照时数和7月份的热量水平是大豆产量形成的主要制约因素。2)从三个气象要素对比看,热量水平对大豆产量制约作用最为显著。对大豆生长发育有利的气候因素是:七月份降水比较充沛,能够充分满足大豆开花结英对水分的迫切需求,大豆生育期的日照时数(除5月下旬至6月中旬)基本上能满足豆生长发育的需求。它对生产部门制订大豆生产管理措施,寻求提高大豆单产的途径,具有重要的参考价值。
In this paper, the average daily temperature, precipitation and sunshine hours from 1971 to 1985 in Zhao light farm were used to make regression analysis and regression analysis based on the measured data of ten days and the output of Heihe No.3 soybean plots. The conclusions are as follows . The unfavorable climatic factors affecting the growth and development of soybean under the ecological conditions of Zhao light area are as follows: 1) From the time section, the daily average temperature, precipitation, sunshine duration and the heat level in July from the end of May to the middle of June are Soybean yield formation of the main constraints. 2) From the comparison of the three meteorological elements, the heat level has the most significant effect on the soybean yield. The favorable climatic factors for the growth and development of soybean are: abundant precipitation in July, which can fully meet the urgent need of moisture for flowering of soybean, and the sunshine hours in the growth period of soybean (except late May to mid-June) can basically satisfy Demand for growth and development of beans. It is an important reference value for the production department to formulate soybean production management measures to seek ways to improve soybean yield.
