我室于1978—1980年,以分期播种为手段,采取生长解析测定法,对山东省2个大豆中熟品种丰收黄与文丰5号进行试验,自6月5日至6月30日每5天播一期。为了探讨气象条件对大豆产量的影响程度,本文汇总三年来的试验数据,进行数理统计分析并依此建立了以气象条件预告大豆产量的方程。由于三年试验中品种一致,地力较均匀,每年试验小区均有四次重复,观测、考种方法统一,故所得资料较为准确。
My room from 1978 to 1980, by means of sowing by stages, using growth analysis assay, Shandong Province, two soybean varieties Harvest Harvest yellow and Wenfeng 5, from June 5 to June 30 every 5 days a broadcast. In order to explore the impact of weather conditions on soybean yield, this paper summarizes the experimental data over the past three years, carries out mathematical statistical analysis and establishes the equation of forecasting soybean yield based on meteorological conditions. As the three years of testing the same species, more uniform soil, the test plot each year has four replications, observation, test a unified method, so the information obtained is more accurate.
