| 摘 要： | 茎蘖数的多少是冬小麦达到最佳产量的关键因素,也是氮肥调控的重要指标.然而为了获得一个代表性的茎蘖数,传统的人工数分蘖的方法费时费力.近年来,随着遥感,特别是主动遥感技术的长足发展,为解决这个问题提供了机遇.文章通过2008年-2009年在河北曲周县中国农业大学试验站的播期、播量和氮水平田间试验,采用主动光谱仪Green...

| Abstract: | Tiller density plays an important role in attaining optimum grain yield and applying topdressing N in winter wheat.However,the traditional approach based on determining tiller density is time-consuming and labor-intensive.As technology advances,remote sensing might provide an opportunity in eliminating this7 problem.In the present paper,an N rate experiment and a variety-seeding and sowing dates experiment were conducted in Quzhou County,Hebei Province in 2008/2009 to develop the models to predict the amoun... |
