摘要
本文通过湟源县寺寨乡青稞地土壤样品的测定,分析了青稞立地土壤养分状况和配方肥施用效果,研究结果表明:2水平氮、磷和钾(N2P2K2)产量最高,氮、磷、钾的缺素相对产量分别为81.46%、83.79%、84.70%,增产效果依次为氮>磷>钾;施配方肥好于习惯施肥,增产39.5%;青稞配方肥总的研制原则是增氮、增磷、增钾。
The objective of this study was to analyse the soil nutrients and formulated fertilizer effects by measuring the soil samples from the Hordeum vulgare L at Si zhai Village,Huangyuan County.The results showed that the yield in the second level of N,P and K(N2P2K2)was the highest.The relative yields were 81.46% for N deficiency,83.79% for P deficiency,and 84.70% for K deficiency.The yield increase of production followed the order of N>P>K.The yield generated from the formula fertilization condition was ...
