| 摘 要： | 2002年秋对黑龙江省友谊农场精准农业试验区进行土壤采样，测定土壤肥力指标，并据此确定2003年春播大豆的变量施肥处方。在大豆鼓粒初期(R5)，利用GPS随机确定不同施肥组合的位置，并进行大豆生长情况调查，结果表明，大豆在本技术下可实现生育指标的均衡一致。

| Abstract: | In the fall of the year 2002, the soil samples were done in the precision agriculture test region of Youyi Farm in Heilongjiang with the index of soil fertility being analyzed. And it was therefore decided on how to prescribe for the variable fertilization of spring seeding soybeans in 2003. At R5 stage of soybeans, we had positioned the sites of different fertilization combination at random by GPS and investigated the growth for soybeans. The results showed that there were no significant differences between plant height andleafareaofsoybeans. |
