你想要这样的东西吗？

固定宽度

\documentclass[tikz,border=10pt,multi]{standalone}
\usepackage{forest}
\usetikzlibrary{backgrounds}
\tikzset{
  basic/.style = {line width=1pt,draw=black},
  L0/.style = {align=left,  fill=green!30},
  L1/.style = {align=left, fill=green!20,},
  L2/.style = {align=left, fill=pink!60, },
  L3/.style = {align=left, fill=pink!10},
  t0/.style={text width=2cm,},
  t1/.style={text width=6cm,},
  t2/.style={text width=9em},
  t3/.style={text width=5em},
}
