小麦拔节期农学参数和土壤含水量空间统计（Spatial Statistic Properties of Agronomic Parameters and Soil Moisture Content in Wheat Jointing Stage）
冬小麦 农学参数 土壤
2009/11/3
选取山东省陵县的小麦试验示范基地作为样区，采用GPS定位调查，获取田间21个样点的土壤和小麦植株样品，运用TDR300测定样点土壤含水量，利用SPAD-502叶绿素仪测定采样点拔节期小麦植株叶片的叶绿素含量，获取小麦干物质产量信息。基于地统计学原理，结合空间分析技术，探讨了小麦叶绿素含量、干物质产量等农学参数信息和土壤含水量的空间变异特征。研究结果表明，土壤水分和小麦叶绿素含量的空间变异呈强的空间...
Effect of Nitrogen Topdressing at Jointing Stage or Anthesis on the Kernel Weight of Hokkadido-Bred Wheat Cultivar “Haruyutaka” in Warm Parts of Western Japan
