于 1998、1999年 ,采用钾肥 5水平 3重复单因素设计方案试验 ,获得处理比对照产量平均增产率分别为 5 7.13%、12 .2 1%、11.80 %、5 .6 9% ;粗蛋白、抗坏血酸 (VC)、Ca、P含量均高于对照 ,叶绿素、Fe、K达到显著水平。在当地土壤生态条件下 ,以施 90kg/公顷加拿大钾肥效益最佳
In 1998 and 1999, the average yield of 5-level and 3-factor single factor design of potash fertilizer was 5 7.13%, 12.21%, 11.80% and 5.96% respectively. The crude protein, Ascorbic acid (VC), Ca, P contents were higher than the control, and chlorophyll, Fe and K reached significant levels. In the local soil ecological conditions, to apply 90kg / hectare potassium fertilizer in Canada is the best
