antd form表单中如何嵌套自定义组件

<Form.Item label="周期" labelAlign="right">
    {getFieldDecorator('cycle', {
        rules: [{ required: true, validator: checkCycle }],
        initialValue: cycle,
    })(<CycleInput cycleOptions={cycleOptions} />)}

     }
     if (format[1] === 'undefined') {
         return Promise.reject(new Error('请选择周期!'));
     }
     const num = +format[0];
     if (num > 0 && format[1]) {
         return Promise.resolve();
     }
