油菜是我国第一大国产植物油来源, 大田生产中需要施加适量的微肥以提高产量和品质。 筛选出一种可提高油菜产量的微肥配方需要经过复杂的大田统计和产量测定, 因此构建出能快速筛选微肥的模型十分重要。 以高油酸油菜“帆鸣1号”为试验材料, 使用地物波谱仪测定了不同微肥条件下全生育期的光谱反射率, 并用乙醇提取法准确测定叶绿素含量。 将光谱反射率、 叶绿素含量和最终产量性状两两间进行相关性分析。 产量测定表明, 施加微肥可以提高油菜产量和蕾薹期时叶绿素的含量, 使单株产量最高提高2%。 光谱参数与叶绿素相关性分析表明, 蕾薹期时叶绿素含量与光谱参数550和720 nm相关性较高, 表明蕾...

Rape is the largest domestic plant oil source in China. It is necessary to apply appropriate micro fertilizer in field production to improve yield and quality. It is very important to build a model which can quickly screen the micronutrient fertilizer to improve the yield of rape. In this research, the spectral reflectance of high oleic acid rape "FanMing No.1" in the whole growth period under different micro fertilizer conditions was measured by ground object spectrometer. And chlorophyll content was accurately determined by ethanol extraction...
