当我在laravel.delete.blade.php中使用资源控制器时，我不明白如何调用destroy方法

@extends('main')

@section('content')
<form method="POST" action="{{route('posts.destroy', '$post->id') }}"  >
@method('DELETE')
@csrf
    <select name="id">
        <option value="1">vddv</option>
        <option value="2">miss</option>
        <option value="3">miss</option>
        <option value="4">joy</option>
    </select>

      <br><br>
    <button type="submit"> Delete blog</button>
</form>
@endsection

资源控制器：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use App\posts;
use Sessions; 

class PostController extends Controller
{ 
    public function create()
    {
        return view('posts.create');   
    }

    public function store(Request $request)
    {
       $post = new posts;
        $post->title = $request->input('title');
        $post->body = $request->input('body');
        $post->save();
        return redirect('posts/read');
    }

    public function show($data)
    {
       echo "show";
    }

    public function edit($id)
    {
        return view('posts.edit');
    }

    public function update(Request $req, $id)
    {
        echo posts::where('title' , $req->title)
        ->update(['body'=>$req->body]);
        return redirect('/');
    }

    public function destroy($id)
    {
        $post = posts::find($id);
        $post->delete();
        return redirect('/');

    }
}

途径：

Route::resource('posts', 'PostController');

当GET请求被传递时，它正在调用show方法。请指导我如何调用destroy方法。正如文档中提到的，我正在使用表单方法欺骗传递@method（'DELETE'），因为html只识别GET和POST方法。
