不同施钾方法对大麻产量的影响

Studies on the Effects of KCl Applying Methods and Logistic Equation Analysis of Hemp Plant height Growth

结果表明 :在施钾与不施钾的情况下 ,大麻株高生长符合Logistic曲线方程 ;大麻施钾能显著提高麻皮产量 ,不同的施钾量和施肥方法增产效果有差异 ,以 30 0kg/hm2 氯化钾追施增产效果最好 ;钾肥追施能提高麻皮厚度 。

In this paper, the experimental data from KCl applied on hemp growth for two years were statistically analyzed. The results showed that the model of plant height growth was a logistic equation The effect of KCl application on yield was significant. There were significant differences in increasing yield in the experiment. The best method was top dressed of 300 kg/hm 2 KCl. Top dressing can increase bark thickness,and base fertilizer + top-dressing can increase fiber and bark tension
